If sin never entered the world, life would be very different than the one we know now. At the creation of the world, God pronounced after each day of creation that what He created was good (vs. 4, 10, 12, 18, 21, 25). But at the last day, He declared that all His cumulative work was very good (Genesis 1:31). The world was brought forth from the Creator’s hand in a state of complete perfection – no trace of evil in it.
Adam and Eve didn’t know of suffering, pain, sickness, wars…or death. They lived in perfect peace and harmony with God, each other, and all creation. Nature was subject to them and they ruled over it with love.
This same perfect life will be the future destiny of the redeemed in the New Earth. The redeemed will have everlasting joy (Isaiah 35:10). For they will experience no more suffering or death (Revelation 21:4). And if any one hurts himself, the leaves of the tree of life will heal him (Revelation 22:2).
The redeemed will have sweet fellowship with God (Isaiah 66:23) and with their fellow men (Zechariah 8:5) and live in perfect harmony. They will enjoy all the pleasures of life that God has prepared for them (Psalm 16:11). They will delight in the beauty of nature (Isaiah 35:1) and appreciate God’s creatures (Isaiah 11:6). They will enjoy the work of their hands and build their dream homes (Isaiah 65:21-22).
The realities of the New Earth, the inexpressible wonder and beauty, the joy of God’s kingdom of glory, and the eternal home of the saved cannot be fully understood by our limited mind. All such knowledge is far beyond anything that we can now know. The Bible describes that life this way, “Eye has not seen, nor ear heard, nor have entered into the heart of man the things which God has prepared for those who love Him” (1 Corinthians 2:9).
