People were created to exist forever. We will either exist eternally separated from God by sin, or eternally with God through forgiveness and salvation. To be eternally separated from God is Hell. To be eternally in union with him is eternal life. Heaven and Hell are real places of eternal existence.
John 3:16*
For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
John 2:25
He did not need man's testimony about man, for he knew what was in a man.
John 5:11-13
But he replied, "The man who made me well said to me, 'Pick up your mat and walk.'" [12] So they asked him, "Who is this fellow who told you to pick it up and walk?" [13] The man who was healed had no idea who it was, for Jesus had slipped away into the crowd that was there.
Romans 6:23
For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.
Revelations 20:15
If anyone's name was not found written in the book of life, he was thrown into the lake of fire.
Revelations 21:1-5
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. [2] I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband. [3] 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. [4] 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." [5] He who was seated on the throne said, "I am making everything new!" Then he said, "Write this down, for these words are trustworthy and true."
Matthew 25:41-46
Then he will say to those on his left, "Depart from me, you who are cursed, into the eternal fire prepared for the devil and his angels. [42] For I was hungry and you gave me nothing to eat, I was thirsty and you gave me nothing to drink, [43] I was a stranger and you did not invite me in, I needed clothes and you did not clothe me, I was sick and in prison and you did not look after me." [44] They also will answer, 'Lord, when did we see you hungry or thirsty or a stranger or needing clothes or sick or in prison, and did not help you?" [45] He will reply, "I tell you the truth, whatever you did not do for one of the least of these, you did not do for me." [46] Then they will go away to eternal punishment, but the righteous to eternal life.
