(Rev. 20:5-6 KJV) 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 is the raising to life of all of Gods people throughout all time. It doesn’t take place at once.
Jesus brought victory over death and is the firstfruits. Then the Rapture of the Church, Tribulation Saints, and then OT Saints.
(1 Cor. 15:20-24 KJV) 20 But now is Christ risen from the dead, and become the firstfruits of them that slept.
21 For since by man came death, by man came also the resurrection of the dead.
22 For as in Adam all die, even so in Christ shall all be made alive.
23 But every man in his own order: Christ the firstfruits; afterward they that are Christ’s at his coming.
24 Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power.
(1 Thess. 4:13-17 KJV) 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.1
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.
(Ps. 50:1-6 KJV) The mighty God, even the LORD, hath spoken, and called the earth from the rising of the sun unto the going down thereof.1
2 Out of Zion, the perfection of beauty, God hath shined.
3 Our God shall come, and shall not keep silence: a fire shall devour before him, and it shall be very tempestuous round about him.
4 He shall call to the heavens from above, and to the earth, that he may judge his people.
5 Gather my saints together unto me; those that have made a covenant with me by sacrifice.
6 And the heavens shall declare his righteousness: for God is judge himself. Selah.
(Rev. 1:5-6 KJV) 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.
We are priests of God and of Christ. This shows the two natures of Jesus – lion and lamb, root and offspring, God and man.
We will reign during the 1000 years of peace.
After the 1000 of peace the rest of the dead will be raised. Those who resurrect to the second death will be raised to judgement.
(Rev. 20:12-13 KJV) 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.
13 And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works.1
(Isa. 26:19-21 KJV) 19 Thy dead men shall live, together with my dead body shall they arise. Awake and sing, ye that dwell in dust: for thy dew is as the dew of herbs, and the earth shall cast out the dead.
20 Come, my people, enter thou into thy chambers, and shut thy doors about thee: hide thyself as it were for a little moment, until the indignation be overpast.
21 For, behold, the LORD cometh out of his place to punish the inhabitants of the earth for their iniquity: the earth also shall disclose her blood, and shall no more cover her slain.1
(Dan. 12:2 KJV) 2 And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt.
(Dan. 12:13 KJV) 13 But go thou thy way till the end be: for thou shalt rest, and stand in thy lot at the end of the days.1
