51 Behold! I tell you a mystery. We shall not all sleep, but we shall all be changed,52 in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised imperishable, and we shall be changed.53 For this perishable body must put on the imperishable, and this mortal body must put on immortality.54 When the perishable puts on the imperishable, and the mortal puts on immortality, then shall come to pass the saying that is written: “Death is swallowed up in victory.”55 “O death, where is your victory? O death, where is your sting?”56 The sting of death is sin, and the power of sin is the law.57 But thanks be to God, who gives us the victory through our Lord Jesus Christ.
1 Thessalonians 4
14 For since we believe that Jesus died and rose again, even so, through Jesus, God will bring with him those who have fallen asleep.
John 11
25 Jesus said to her, “I am the resurrection and the life. Whoever believes in me, though he die, yet shall he live,26 and everyone who lives and believes in me shall never die. Do you believe this?”
Revelation 21
4 He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away.”
