Zechariah 14:16-20
16 And it shall come to pass that everyone who is left of all the nations which came against Jerusalem shall go up from year to year to worship the King, the Lord of hosts, and to keep the Feast of Tabernacles.
Isaiah 25:6-8
And in this mountain
The Lord of hosts will make for all people
A feast of [c]choice pieces,
A feast of [d]wines on the lees,
Of fat things full of marrow,
Of well-refined wines on the lees.
7 And He will destroy on this mountain
The surface of the covering cast over all people,
And the veil that is spread over all nations.
8 He will swallow up death forever, (Rev 21:1-4,1 Corth 15:26, Isaiah 35:10, 51:11, 65:19)
And the Lord God will wipe away tears from all faces;
The rebuke of His people
He will take away from all the earth;
For the Lord has spoken.
Marriage super of the Lamb (Rev 19:6-9) is the Feast of Tabernacles, it's the last and most grandest feast.
ECF/Reformation quotes on the topic of what happens when we die:
Justin and Trypho dialog, Chapter 80. The opinion of Justin about the reign of a thousand years:
For I (Justin) choose to follow not men or men's doctrines, but God and the doctrines [delivered] by Him. For if you have fallen in with some who are called Christians, but who do not admit this [truth], and venture to blaspheme the God of Abraham, and the God of Isaac, and the God of Jacob; who say there is no resurrection of the dead, and that their souls, when they die, are taken to heaven; do not imagine that they are Christians, even as one, if he would rightly consider it, would not admit that the Sadducees, or similar sects of Genistæ, Meristæ, Galilæans, Hellenists, Pharisees, Baptists, are Jews (do not hear me impatiently when I tell you what I think), but are [only] called Jews and children of Abraham, worshipping God with the lips, as God Himself declared, but the heart was far from Him. But I and others, who are right-minded Christians on all points, are assured that there will be a resurrection of the dead, and a thousand years in Jerusalem, which will then be built, adorned, and enlarged, [as] the prophets Ezekiel and Isaiah and others declare.
MARTIN LUTHER (1493-1546), German Reformer and Bible translator
Here are sample Luther citations. In the quaint 1573 English translation we read:
“Salomon judgeth that the dead are a sleepe, and feele nothing at all. For the dead lye there accompting neyther dayes nor yeares, but when are awaked, they shall seeme to have slept scarce one minute.” 18 “But we Christians, who have been redeemed from all this through the precious blood of God’s Son, should train and accustom ourselves in faith to despise death and regard it as a deep, strong, sweet sleep; to consider the coffin as nothing other than our Lord Jesus’ bosom or Paradise, the grave as nothing other than a soft couch of ease or rest. As verily, before God, it truly is just this; for he testifies, John 11:11; ‘Lazarus, our friend sleeps’; Matthew 9:24: ‘The maiden is not dead, she sleeps.’ Thus, too, St. Paul in 1 Corinthians 15, removes from sight all hateful aspects of death as related to our mortal body and brings forward nothing but charming and joyful aspects of the promised life. He says there [vv. 42ff]: ‘It is sown in corruption and will rise in incorruption; it is sown in dishonor (that is, a hateful, shameful form) and will rise in glory; it is sown in weakness and will rise in strength; it is sown in natural body and will rise a spiritual body.”19 “Thus after death the soul goes to its bedchamber and to its peace, and while it is sleeping it does not realize its sleep, and God preserves indeed the awakening soul. God is able to awake Elijah, Moses, and others, and so control them, so that they will live. But how can that be? That we do not know; we satisfy ourselves with the example of bodily sleep, and with what God says: it is a sleep, a rest, and a peace. He who sleeps naturally knows nothing of that which happens in his neighbor's house; and nevertheless, he still is living, even though, contrary to the nature of life, he is unconscious in his sleep. Exactly the same will happen also in that life, but in another and a better way. 20”
“We should learn to view our death in the right light, so that we need not become alarmed on account of it, as unbelief does; because in Christ it is indeed not death, but a fine, sweet and brief sleep, which brings us release from this vale of tears, from sin and from the fear and extremity of real death and from all the misfortunes of this life, and we shall be secure and without care, rest sweetly and gently for a brief moment, as on a sofa, until the time when he shall call and awaken us together with all his dear children to his eternal glory and joy. For since we call it a sleep, we know that we shall not remain in it, but be again awakened and live, and that the time during which we sleep, shall seem no longer than if we had just fallen asleep. Hence, we shall censure ourselves that we were surprised or alarmed at such a sleep in the hour of death, and suddenly come alive out of the grave and from decomposition, and entirely well, fresh, with a pure, clear, glorified life, meet our Lord and Savior Jesus Christ in the clouds. … Scripture everywhere affords such consolation, which speaks of the death of the saints, as if they fell asleep and were gathered to their fathers, that is, had overcome death through this faith and comfort in Christ, and awaited the resurrection, together with the saints who preceded them in death.”
WILLIAM TYNDALE (1484-1536), English Bible translator and martyr
“And ye, in putting them (the departed souls) in heaven, hell, and purgatory, destroy the arguments wherewith Christ and Paul prove the resurrection.... And again, if the souls be in heaven, tell me why they be not in as good case as the angels be? And then what cause is there of the resurrection?”
“The true faith putteth (setteth forth) the resurrection, which we be warned to look for every hour. The heathen philosophers, denying that, did put (set forth) that the souls did ever live. And the pope joineth the spiritual doctrine of Christ and the fleshly doctrine of philosophers together; things so contrary that they cannot agree, no more than the Spirit and the flesh do in a Christian man. And because the fleshly-minded pope consenteth unto heathen doctrine, therefore he corrupteth the Scripture to stablish it.”
“Nay, Paul, thou art unlearned; go to Master More, and learn a new way. We be not most miserable, though we rise not again; for our souls go to heaven as soon as we be dead, and are there in as great joy as Christ that is risen again. And I marvel that Paul had not comforted the Thessalonians with that doctrine, if he had wist (known) it, that the souls of their dead had been in joy; as he did with the resurrection, that their dead should rise again. If the souls be in heaven, in as great glory as the angels, after your doctrine, shew me what cause should be of the resurrection).”
In modern terms, what Tyndale is trying to say is, if when you die your ghost goes to heaven and you're in eternal bliss and joy with the Father and Son, and are skipping down a yellow brick road with all your rewards, then what is the point of a resurrection. If the immortality soul doctrine is true, then you make the resurrection of Christ worthless, empty, and meaningless.
It's only through the resurrection and granted access to eat from tree of life (Rev 2:7, 22:1-3 ->Ezekiel 47:1-12) can we sing, worship, love, play, laugh, and be in joy. The tree of life that Adam was kicked out of least he eat and live forever (Gen 3:22).
