What does the Bible say about heaven and eternal life?

“Jesus said to her, “I am the resurrection and the life. He who believes in me will still live, even if he dies. Whoever lives and believes in me will never die. Do you believe this?””

“But we don’t want you to be ignorant, brothers, concerning those who have fallen asleep, so that you don’t grieve like the rest, who have no hope. For if we believe that Jesus died and rose again, even so God will bring with him those who have fallen asleep in Jesus.”

“We are courageous, I say, and are willing rather to be absent from the body and to be at home with the Lord.”

“He will wipe away every tear from their eyes. Death will be no more; neither will there be mourning, nor crying, nor pain any more. The first things have passed away.””

“In my Father’s house are many homes. If it weren’t so, I would have told you. I am going to prepare a place for you. If I go and prepare a place for you, I will come again and will receive you to myself; that where I am, you may be there also.”

“For our citizenship is in heaven, from where we also wait for a Savior, the Lord Jesus Christ, who will change the body of our humiliation to be conformed to the body of his glory, according to the working by which he is able even to subject all things to himself.”

“Behold, I tell you a mystery. We will not all sleep, but we will all be changed, in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound and the dead will be raised incorruptible, and we will be changed. For this perishable body must become imperishable, and this mortal must put on immortality. But when this perishable body will have become imperishable, and this mortal will have put on immortality, then what is written will happen: “Death is swallowed up in victory.” “Death, where is your sting? Hades, where is your victory?””

“There will be no night, and they need no lamp light or sun light; for the Lord God will illuminate them. They will reign forever and ever.”
