The following is to show that the apostles had to be literal witnesses of Christ’s resurrection. The fact that they could all die off didn’t matter because Christ was expected to come the second time before that happened.
How were they chosen? Here is no mention of laying on of hands, just casting lots; also an apostle was a physical witness of Jesus Christ:
Acts 1:
21 Wherefore of these men which have companied with us all the time that the Lord Jesus went in and out among us,
22 Beginning from the baptism of John, unto that same day that he was taken up from us, must one be ordained to be a witness with us of his resurrection.
23 And they appointed two, Joseph called Barsabas, who was surnamed Justus, and Matthias.
24 And they prayed, and said, Thou, Lord, which knowest the hearts of all men, shew whether of these two thou hast chosen,
25 That he may take part of this ministry and apostleship, from which Judas by transgression fell, that he might go to his own place.
26 And they gave forth their lots; and the lot fell upon Matthias; and he was numbered with the eleven apostles.
Here Paul tells his story of how he became an apostle (no mention of ordination by laying on of hands):
Gal.1:
16 To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood:
17 Neither went I up to Jerusalem to them which were apostles before me; but I went into Arabia, and returned again unto Damascus.
18 Then after three years I went up to Jerusalem to see Peter, and abode with him fifteen days.
19 But other of the apostles saw I none, save .James the Lord’s brother.
20 Now the things which I write unto you, behold, before God, I lie not.
21 Afterwards I came into the regions of Syria and Cilicia;
22 And was unknown by face unto the churches of Judaea which were in Christ:
23 But they had heard only, That he which persecuted us in times past now preacheth the faith which once he destroyed.
Gal. 2:
1 Then fourteen years after I went up again to Jerusalem with Barnabas, and took Titus with me also.
2 And I went up by revelation, and communicated unto them that gospel which I preach among the Gentiles, but privately to them which were of reputation, lest by any means I should run, or had run, in vain.
3 But neither Titus, who was with me, being a Greek, was compelled to be circumcised:
4 And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage:
5 To whom we gave place by subjection, no, not for an hour; that the truth of the gospel might continue with you.
6 But of these who seemed to be somewhat, (whatsoever they were, it maketh no matter to me: God accepteth no man’s person:) for they who seemed to be somewhat in conference added nothing to me:
7 But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter;
8 (For he that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles:)
9 And when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we should go unto the heathen, and they unto the circumcision.
Christ appeared to Paul so he could be a witness/apostle:
Acts 26:
15 And I said, Who art thou, Lord? And he said, I am Jesus whom thou persecutest.
16 But rise, and stand upon thy feet: for I have appeared unto thee for this purpose, to make thee a minister and a witness both of these things which thou hast seen, and of those things in the which I will appear unto thee;
Cor. 9:
1 Am I not an apostle? am I not free? have I not seen Jesus Christ our Lord? are not ye my work in the Lord?
2 If I be not an apostle unto others, yet doubtless I am to you: for the seal of mine apostleship are ye in the Lord.
Christ ordained Paul (refer to Acts 26):
Tim 2:
7 Whereunto I am ordained a preacher, and an apostle, (I speak the truth in Christ, and lie not;) a teacher of the Gentiles in faith and verity.
1 Cor. 15:
1 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
2 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
4 And that he was buried, and that he arose again the third day according to the scriptures:
5 And that he was seen of Cephas, then of the twelve:
6 After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep.
7 After that, he was seen of James; then of all the apostles.
8 And last of all he was seen of me also, as of one born out of due time.
9 For I am the least of the apostles, that am not meet to be called an apostle, because I persecuted the church of God.
14 And if Christ be not risen, then is our preaching vain, and your faith is also vain.
15 Yea, and we are found false witnesses of God; because we have testified of God that he raised up Christ: whom he raised not up, if so be that the dead rise not.
The apostles were to gather the lost tribes:
James 1:
1 James, a servant of God and of the Lord Jesus Christ, to the twelve tribes which are scattered abroad, greeting.
Paul explains that the sacrifices of those under the first testament were not enough to redeem them from their sins, but Christ’s sacrifice covered for those under the first testament who were “called” (elect/chosen). This explains why he thought Christ came in the “end of the world” and the “last days”, so that his sacrifice would cover all those who came before him as well as the ones living in the present until his second coming. Only those who received the gospel before they died (the foreordained/predestined elect) would be saved, because preaching to the spirits in prison was done by Christ who was not there any more, but in heaven, and the elect were sure to receive it (Romans 11: 1-7). This also explains why only the spirits of those who died in the flood are mentioned as being taught (1 Peter 3: 19-20), because God’s chosen lineage (through Shem) worshiped the true God after the flood (Genesis 9: 26-27):
Hebrews 1:
1 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets,
2 Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;
Hebrews 9:
15 And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
26 For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself.
27 And as it is appointed unto men once to die, but after this the judgment:
28 So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.
Hebrews 10:
1 For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
2 For then would they not have ceased to be offered? because that the worshippers once purged should have had no more conscience of sins.
3 But in those sacrifices there is a remembrance again made of sins every year.
4 For it is not possible that the blood of bulls and of goats should take away sins.
5 Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me:
6 In burnt offerings and sacrifices for sin thou hast had no pleasure.
7 Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God.
8 Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law;
9 Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second.
10 By the which will we are sanctified through the offering of the body of Jesus Christ once for all.
11 And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins:
12 But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God;
36 For ye have need of patience, that, after ye have done the will of God, ye might receive the promise.
37 For yet a little while, and he that shall come will come, and will not tarry.
Romans 11:
1 I say then, Hath God cast away his people? God forbid. For I also am an Israelite, of the seed of Abraham, of the tribe of Benjamin.
2 God hath not cast away his people which he foreknew. Wot ye not what the scripture saith of Elias? how he maketh intercession to God against Israel, saying,
3 Lord, they have killed thy prophets, and digged down thine altars; and I am left alone, and they seek my life.
4 But what saith the answer of God unto him? I have reserved to myself seven thousand men, who have not bowed the knee to the image of Baal.
5 Even so then at this present time also there is a remnant according to the election of grace.
6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work.
7 What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded
1 Peter 3:
19 By which also he went and preached unto the spirits in prison;
20 Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water.
Genesis 9:
26 And he said, Blessed be the Lord God of Shem; and Canaan shall be his servant.
27 God shall enlarge Japheth, and he shall dwell in the tents of Shem; and Canaan shall be his servant.
(One interpretation is that God shall dwell in the tents of Shem.)
The reason Paul said it was doing well to not marry and get distracted from the Lord’s work was because Christ was going to come soon.
1 Cor. 7:
29 But this I say, brethren, the time is short: it remaineth, that both they that have wives be as though they had none;
30 And they that weep, as though they wept not; and they that rejoice, as though they rejoiced not; and they that buy, as though they possessed not;
31 And they that use this world, as not abusing it: for the fashion of this world passeth away.
32 But I would have you without carefulness. He that is unmarried careth for the things that belong to the Lord, how he may please the Lord:
33 But he that is married careth for the things that are of the world, how he may please his wife.
35 And this I speak for your own profit; not that I may cast a snare upon you, but for that which is comely, and that ye may attend upon the Lord without distraction.
36 But if any man think that he behaveth himself uncomely toward his virgin, if she pass the flower of her age, and need so require, let him do what he will, he sinneth not: let them marry.
37 Nevertheless, he that standeth stedfast in his heart, having no necessity, but hath power over his own will, and hath so decreed in his heart that he will keep his virgin, doeth well.
The anti-Christ was living in their time.
2 Thess. 2:
2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.
3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
5 Remember ye not, that, when I was yet with you, I told you these things?
6 And now ye know what withholdeth that he might be revealed in his time.
7 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way.
8 And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming:
Rather than the meaning of “calling and election made sure” being a visitation from Christ before dying, it could have originally meant having their inheritance redeemed at the second coming of Christ:
2 Peter 1:
10 Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fall:
11 For so an entrance shall be ministered unto you abundantly into the everlasting kingdom of our Lord and Saviour Jesus Christ.
More references to show they expected Christ to come in their lifetimes:
Matt. 16:
27 For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works.
28 Verily I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom.
Mark 13:
29 So ye in like manner, when ye shall see these things come to pass, know that it is nigh, even at the doors.
30 Verily I say unto you, that this generation shall not pass, till all these things be done.
31 Heaven and earth shall pass away: but my words shall not pass away.
32 ¶ But of that day and that hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father.
33 Take ye heed, watch and pray: for ye know not when the time is.
34 For the Son of man is as a man taking a far journey, who left his house, and gave authority to his servants, and to every man his work, and commanded the porter to watch.
35 Watch ye therefore: for ye know not when the master of the house cometh, at even, or at midnight, or at the cockcrowing, or in the morning:
36 Lest coming suddenly he find you sleeping.
37 And what I say unto you I say unto all, Watch.
Luke 12:
37 Blessed are those servants, whom the lord when he cometh shall find watching: verily I say unto you, that he shall gird himself, and make them to sit down to meat, and will come forth and serve them.
38 And if he shall come in the second watch, or come in the third watch, and find them so, blessed are those servants.
39 And this know, that if the goodman of the house had known what hour the thief would come, he would have watched, and not have suffered his house to be broken through.
40 Be ye therefore ready also: for the Son of man cometh at an hour when ye think not.
Luke 21:
27 And then shall they see the Son of man coming in a cloud with power and great glory.
28 And when these things begin to come to pass, then look up, and lift up your heads; for your redemption draweth nigh.
31 So likewise ye, when ye see these things come to pass, know ye that the kingdom of God is nigh at hand.
32 Verily I say unto you, This generation ashall not pass away, till all be fulfilled.
36 Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.
Romans 16:
20 And the God of peace shall bruise Satan under your feet shortly.
Romans 13:
11 And that, knowing the time, that now it is high time to awake out of sleep: for now is our salvation nearer than when we believed.
12 The night is far spent, the day is at hand: let us therefore cast off the works of darkness, and let us put on the armour of light.
1 Cor. 1:
4 I thank my God always on your behalf, for the grace of God which is given you by Jesus Christ;
5 That in every thing ye are enriched by him, in all utterance, and in all knowledge;
6 Even as the testimony of Christ was confirmed in you:
7 So that ye come behind in no gift; waiting for the coming of our Lord Jesus Christ:
8 Who shall also confirm you unto the end, that ye may be blameless in the day of our Lord Jesus Christ.
1 Cor. 4:
9 For I think that God hath set forth us the apostles last, as it were appointed to death: for we are made a spectacle unto the world, and to angels, and to men.
1 Cor. 10:
11 Now all these things happened unto them for ensamples: and they are written for our admonition, upon whom the ends of the world are come.
12 Wherefore let him that thinketh he standeth take heed lest he fall.
1 Cor 15:
51 Behold, I shew you a mystery; We shall not all asleep, but we shall all be changed,
52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
Phil. 1:
3 I thank my God upon every remembrance of you,
4 Always in every prayer of mine for you all making request with joy,
5 For your fellowship in the gospel from the first day until now;
6 Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ:
9 And this I pray, that your love may abound yet more and more in knowledge and in all judgment;
10 That ye may approve things that are excellent; that ye may be sincere and without offence till the day of Christ;
1 Thes. 1:
9 For they themselves shew of us what manner of entering in we had unto you, and how ye turned to God from idols to serve the living and true God;
10 And to wait for his Son from heaven, whom he raised from the dead, even Jesus, which delivered us from the wrath to come.
1 Thes. 2:
19 For what is our hope, or joy, or crown of rejoicing? Are not even ye in the presence of our Lord Jesus Christ at his coming?
1 Thes. 3:
12 And the Lord make you to increase and abound in love one toward another, and toward all men, even as we do toward you:
13 To the end he may stablish your hearts unblameable in holiness before God, even our Father, at the coming of our Lord Jesus Christ with all his saints.
1 Thes. 4:
13 But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope.
14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.
15 For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep.
16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
18 Wherefore comfort one another with these words.
1 Thes. 5:
1 But of the times and the seasons, brethren, ye have no need that I write unto you.
2 For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
3 For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.
4 But ye, brethren, are not in darkness, that that day should overtake you as a thief.
5 Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness.
6 Therefore let us not asleep, as do others; but let us watch and be sober.
23 And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ.
2 Thes. 1:
6 Seeing it is a righteous thing with God to recompense tribulation to them that trouble you;
7 And to you who are troubled rest with us, when the Lord Jesus shall be revealed from heaven with his mighty angels,
8 In flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ:
9 Who shall be punished with everlasting destruction from the presence of the Lord, and from the glory of his power;
10 When he shall come to be glorified in his saints, and to be admired in all them that believe (because our testimony among you was believed) in that day.
2 Tim 4:
8 Henceforth there is laid up for me a crown of righteousness, which the Lord, the righteous judge, shall give me at that day: and not to me only, but unto all them also that love his appearing.
17 Notwithstanding the Lord stood with me, and strengthened me; that by me the preaching might be fully known, and that all the Gentiles might hear: and I was delivered out of the mouth of the lion.
18 And the Lord shall deliver me from every evil work, and will preserve me unto his heavenly kingdom: to whom be glory for ever and ever. Amen.
Titus 2:
13 Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ;
James 5:
7 Be patient therefore, brethren, unto the coming of the Lord. Behold, the husbandman waiteth for the precious fruit of the earth, and hath long patience for it, until he receive the early and latter rain.
8 Be ye also patient; stablish your hearts: for the coming of the Lord draweth nigh.
1 Peter 1:
7 That the trial of your faith, being much more precious than of gold that perisheth, though it be tried with fire, might be found unto praise and honour and glory at the appearing of Jesus Christ:
8 Whom having not seen, ye love; in whom, though now ye see him not, yet believing, ye rejoice with joy unspeakable and full of glory:
9 Receiving the end of your faith, even the salvation of your souls.
10 Of which salvation the prophets have enquired and searched diligently, who prophesied of the grace that should come unto you:
20 Who verily was foreordained before the foundation of the world, but was manifest in these last times for you,
1 Peter 4:
7 But the end of all things is at hand: be ye therefore sober, and watch unto prayer.
2 Peter 3:
11 Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness,
12 Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?
13 Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
14 Wherefore, beloved, seeing that ye look for such things, be diligent that ye may be found of him in peace, without spot, and blameless.
1 John 2:
18 Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time.
28 And now, little children, abide in him; that, when he shall appear, we may have confidence, and not be ashamed before him at his coming.
1 John 3:
2 Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
Jude 1:
16 These are murmurers, complainers, walking after their own lusts; and their mouth speaketh great swelling words, having men’s persons in admiration because of advantage.
17 But, beloved, remember ye the words which were spoken before of the apostles of our Lord Jesus Christ;
18 How that they told you there should be mockers in the last time, who should walk after their own ungodly lusts.
24 Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy,
Rev.1:
1 The Revelation of Jesus Christ, which God gave unto him, to shew unto his servants things which must shortly come to pass; and he sent and signified it by his angel unto his servant John:
2 Who bare record of the word of God, and of the testimony of Jesus Christ, and of all things that he saw.
3 Blessed is he that readeth, and they that hear the words of this prophecy, and keep those things which are written therein: for the time is at hand.
4 JOHN to the seven churches which are in Asia: Grace be unto you, and peace, from him which is, and which was, and which is to come; and from the seven Spirits which are before his throne;
5 And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood,
6 And hath made us kings and priests unto God and his Father; to him be glory and dominion for ever and ever. Amen.
7 Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him. Even so, Amen.
