Heb 6:1 "Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God, 2 Of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment. 3 And this will we do, if God permit."
The resurrection as a fact of the gospel cannot be disputed. Paul emphasized it in all his preaching, both in his first epistle: 1 Thess 1:10 "And to wait for his Son from heaven, whom he raised from the dead, even Jesus, which delivered us from the wrath to come"; and in his last: 2Tim 2:8 "Remember that Jesus Christ of the seed of David was raised from the dead according to my gospel:"
Much can be said of the resurrection, How Jesus was raised up, how we are raised up with Him, and the fact that if Jesus is not raised up we are yet in our sins. (1 Cor 15:17) The doctrine is expounded on in detail in 1 Cor 15; Rom 4-8 and all throughout Acts; which we will not detail here.
The point of this post is to establish the fact that there are two resurrection, divided by time and containing different people. The first, of the just, a resurrection of life. The second, of the unjust, and that brings men to the second death.
Two Resurrections
John 5:24 "Verily, verily, I say unto you, He that hears my word, and believes on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life. 25 Verily, verily, I say unto you, The hour is coming, and now is, when the dead shall hear the voice of the Son of God: and they that hear shall live. 26 For as the Father hath life in himself; so hath he given to the Son to have life in himself; 27 And hath given him authority to execute judgment also, because he is the Son of man. 28 Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice, 29 And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation."
There are in fact two resurrections. One for the just, and one for the evil.
Acts 24:15 "And have hope toward God, which they themselves also allow, that there shall be a resurrection of the dead, both of the just and unjust."
Luke 14:14 "And thou shalt be blessed; for they cannot recompense thee: for thou shalt be recompensed at the resurrection of the just."
The following passage in revelation speaks of the end of the first resurrection, It begins with Jesus and ends with those killed for their witness to the word of God. There is a thousand year separation between the end of the first resurrection and that for "the rest of the dead".
Rev 20:5 "But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection. 6 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years."
The first resurrection brings a people who will be reigning during the thousand years that must pass before the rest of the dead will be raised to judgment.
Rev 20:7 And when the thousand years are expired, Satan shall be loosed out of his prison, 8 And shall go out to deceive the nations ...11 And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them. 12 And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works. ...14 And death and hell were cast into the lake of fire. This is the second death. 15 And whosoever was not found written in the book of life was cast into the lake of fire.
So, clearly, there are two resurrection, one to life and one to death. The call is to believe on Jesus and to be a part of those blessed and happy to be a part of the first resurrection.
