The Bible tells us the rest of the dead come back to life after the thousand years are over. It also describes them as being physical humans and says approximately how long they will enjoy a satisfying life. God is not a pushy salesman. With the earth filled with his knowledge, he will give these people a lifetime to decide if they will follow Jesus or not. Will everyone accept Jesus and the salvation he brings? How many angels rejected God even though they had lived with him in heaven?
Ezekiel 37:1-14 Common English Bible
1 The Lord’s power overcame me, and while I was in the Lord’s spirit, he led me out and set me down in the middle of a certain valley. It was full of bones. 2 He led me through them all around, and I saw that there were a great many of them on the valley floor, and they were very dry. 3 He asked me, “Human one, can these bones live again?” I said, “Lord God, only you know.” 4 He said to me, “Prophesy over these bones, and say to them, Dry bones, hear the Lord’s word! 5 The Lord God proclaims to these bones: I am about to put breath in you, and you will live again. 6 I will put sinews on you, place flesh on you, and cover you with skin. When I put breath in you, and you come to life, you will know that I am the Lord.” 7 I prophesied just as I was commanded. There was a great noise as I was prophesying, then a great quaking, and the bones came together, bone by bone. 8 When I looked, suddenly there were sinews on them. The flesh appeared, and then they were covered over with skin. But there was still no breath in them. 9 He said to me, “Prophesy to the breath; prophesy, human one! Say to the breath, The Lord God proclaims: Come from the four winds, breath! Breathe into these dead bodies and let them live.” 10 I prophesied just as he commanded me. When the breath entered them, they came to life and stood on their feet, an extraordinarily large company. 11 He said to me, “Human one, these bones are the entire house of Israel. They say, ‘Our bones are dried up, and our hope has perished. We are completely finished.’ 12 So now, prophesy and say to them, The Lord God proclaims: I’m opening your graves! I will raise you up from your graves, my people, and I will bring you to Israel’s fertile land. 13 You will know that I am the Lord, when I open your graves and raise you up from your graves, my people. 14 I will put my breath in you, and you will live. I will plant you on your fertile land, and you will know that I am the Lord. I’ve spoken, and I will do it. This is what the Lord says.”
Isaiah 65:20-22 New King James Version
20 “No more shall an infant from there live but a few days, Nor an old man who has not fulfilled his days; For the child shall die one hundred years old, But the sinner being one hundred years old shall be accursed. 21 They shall build houses and inhabit them; They shall plant vineyards and eat their fruit. 22 They shall not build and another inhabit; They shall not plant and another eat; For as the days of a tree, so shall be the days of My people, And My elect shall long enjoy the work of their hands.
