Creation is decaying. According to the Bible this is due to a curse on Creation as a consequence of The Fall of Mankind . But creation will be restored back to perfection one day,
Acts 3:21 "He [Jesus] must remain in heaven until the time comes for God to restore everything, as he promised long ago through his holy prophets."
Romans 8:18-21 "I consider that our present sufferings are not worth comparing with the glory that will be revealed in us. The creation waits in eager expectation for the sons of God to be revealed. For the creation was subjected to frustration, not by its own choice, but by the will of the one who subjected it, in hope that the creation itself will be liberated from its bondage to decay and brought into the glorious freedom of the children of God."
To restore something to it's former glory means it must have once been beautiful. This makes sense if Genesis chapter 1 is literal; there was a perfect paradise, with no death, all animals and mankind at peace together, living as vegetarians. Genesis 1:29,30 "Then God said, "I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food. And to all the beasts of the earth and all the birds of the air and all the creatures that move on the ground - everything that has the breath of life in it - I give every green plant for food." And it was so.". It may seem incredible to think of carnivores living healthily without meat, but there have been recorded incidents, such as a vegetarian lion.
The Bible teaches that one day this current earth will pass away and be replaced with a new earth:
Isaiah 65:17-19, 25 “Look! I am creating new heavens and a new earth—so wonderful that no one will even think about the old ones anymore. Be glad; rejoice forever in my creation! And look! I will create Jerusalem as a place of happiness. Her people will be a source of joy. I will rejoice in Jerusalem and delight in my people. And the sound of weeping and crying will be heard no more. The wolf and lamb will feed together. The lion will eat straw like the ox. Poisonous snakes will strike no more. In those days, no one will be hurt or destroyed on my holy mountain. I, the Lord, have spoken!
Isaiah 11:6-9 "In that day the wolf and the lamb will live together; the leopard and the goat will be at peace. Calves and yearlings will be safe among lions, and a little child will lead them all. The cattle will graze among bears. Cubs and calves will lie down together. And lions will eat grass as the livestock do. Babies will crawl safely among poisonous snakes. Yes, a little child will put its hand in a nest of deadly snakes and pull it out unharmed. Nothing will hurt or destroy in all my holy mountain. And as the waters fill the sea, so the earth will be filled with people who know the Lord."
Revelation 21:1-4 "Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and there was no longer any sea. I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband. And I heard a loud voice from
the throne saying, "Now the dwelling of God is with men, and he will live with them. They will be his people, and God himself will be with them and be their God. He will wipe every tear from their eyes. There will be no more death or mourning or crying or pain, for the old order of things has passed away.""
The wolf and lamb feed together, lions eat grass and an end to poisonous animals. Some may say this is not meant to be taken literally, but others believe these are clear prophesies; in the new earth there will be no more death, animals and mankind will live in harmony as vegetarians, restored to how it was in the beginning. No death or pain - creation restored.
However, this interpretation isn't compatible with Theistic Evolution, as there isn't a restoration point when everything was good.
Think of it like a computer restore point. Operating systems create "restore points" when the computer is working properly so that if a problem such as a virus is introduced, the computer can be restored back to health. Sin and death is the virus of the world. According to the Young Earth creationism model there is a restore point, when everything was perfect in the garden of Eden.
What if the computer is infected with a virus from when it was created (the Theistic Evolution model)? Then it wouldn't be possible to restore back to a point when it was free from the virus.
