Looks into the future within the Old Testament are common. That is what prophecy is. We are living far enough in the future from the time of Isaiah that almost everything in it we can examine through hindsight. Almost.
Isaiah had warnings for the people of Israel and for the surrounding nations. It has all come true to my knowledge. It is so accurate that skeptics conclude that Isaiah had to be written after the fact, but there is no proof of this. Isaiah also spoke a lot about the coming of Jesus: virgin birth, living in Galilee, heir of David, widely rejected by the Jews, put through a judgment process where He did not defend himself, crucified for the salvation of others, and buried with the rich. They would be impossible or undesirable events to stage.
Toward the end of Isaiah there is a large and confusing section about the New Earth which is still future even to us. Check out my take on this section here: https://afterdeathsite.com/2022/05/24/wrestling-with-isaiah-65/
Then there are the final verses of the last chapter. It speaks about some stuff that is in our rear-view mirror and some that is not. It starts like this:
18 “For I know their works and their thoughts, and the time is coming to gather all nations and tongues. And they shall come and shall see my glory, 19 and I will set a sign among them. And from them I will send survivors to the nations, to Tarshish, Pul, and Lud, who draw the bow, to Tubal and Javan, to the coastlands far away, that have not heard my fame or seen my glory. And they shall declare my glory among the nations.
Isaiah 66:18-19 (ESV)
It is intriguing (to me) to ponder what constituted the right time to send Jesus to fulfill the Law and create an opening for people to have eternal life with God starting with Heaven and then later adding the New Earth. With this event comes a spreading out of knowledge about the God who encountered Israel for millennia, the events around Jesus’ life, and the promise of eternal life. God didn’t keep His promise within the borders of a chosen people. He opened the doors to everyone starting most likely 33AD. His description of “the nations” is strange to us, but must have been well known to the contemporaries of Isaiah. “They” in verse 19 must be the early disciples. The communication of God’s actions and the promise of eternal life continues with the disciples of Jesus today all around the world.
20 And they shall bring all your brothers from all the nations as an offering to the Lord, on horses and in chariots and in litters and on mules and on dromedaries, to my holy mountain Jerusalem, says the Lord, just as the Israelites bring their grain offering in a clean vessel to the house of the Lord. 21 And some of them also I will take for priests and for Levites, says the Lord.
Isaiah 66:20-21 (ESV)
Not only was it surprise to hear that God would reach out to other nations, but an even bigger surprise that some of them would be used like the priests and Levites. This chosen group served in the temple as their sole occupation. They were chosen because of the faithfulness of one clan during the Exodus. In the future this would be opened up. I am such a person.
Another surprise is that these saved foreigners would be “your brothers”. This is not a promise to gather the dispersed Jewish people but rather to gather the elect from every nation. These are people whom God can foresee that He will be able to reach. Not everyone will embrace the promise of Jesus. This is sadly observable. Why? I’m not sure the cause or causes. But some will.
The weird modes of transportation are interesting too. I have never brought somebody to church on a dromedary. But this isn’t transportation to a place exactly. This is being involved in diverse ways in people’s lives so that they are connected to Jesus and when we all move past Judgment Day and to the New Jerusalem (Revelation 21-22), we will be like a grain offering that makes God very happy. The New Jerusalem is a place. We just help bring people to Jesus.
“For as the new heavens and the new earth
that I make
shall remain before me, says the Lord,
so shall your offspring and your name remain.
23 From new moon to new moon,
and from Sabbath to Sabbath,
all flesh shall come to worship before me,
declares the Lord.Isaiah 66:22-23 (ESV)
Eternal life with God is just that–eternal. That is the consistent message of the rest of Scripture. This passage speaks of the permanence of the New Heavens and New Earth, the offspring of the people of faith within Israel, and their name. Part of our experience in Heaven and the New Earth will be worship. Don’t relate that to times you were bored in church. It is also notable that it is “all flesh”. Humans aren’t complete as a disembodied spirit. Paul calls that being “naked” (2 Corinthians 5). We will have a Heavenly Body and a resurrected Earthly body. Worship will be an immersive and positive experience. Everyone will do it. Everyone who is saved that is.
24 “And they shall go out and look on the dead bodies of the men who have rebelled against me. For their worm shall not die, their fire shall not be quenched, and they shall be an abhorrence to all flesh.”
I don’t think that we will make it a part of our eternal routine to observe “dead bodies”. The Bible says that everybody (saved and not) will be a part of the resurrection of our earthly bodies. While this may seem like an amazing and hopeful moment, those who stand judgment bearing their own sin rather than the righteousness we receive from Jesus will find their resurrected bodies are not indestructible. Malachi 4 speaks about them being turned to ash. That will be observable on Judgment Day, probably not after it.
The spirit of a damned person then experiences the ultimate consequence for sin that was completely avoidable. By rejecting Jesus they allowed themselves to bear the full consequence of the Law. They will experience an unending decay (the worm does not die), a fire that is never quenched, be abhorrent to themselves and others, and forsaken by God.
For my part, I wish this ended at verse 23. I can’t deny verse 24 and others like it. Jesus says many will enter destruct and few into life. I hope those relative terms do not mean like they sound. It sure sounds like the majority will experience verse 24.
