1 Corinthians 15:51–54
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..
Christian hopes foundation is found in the resurrection, but the resurrection isn’t what happens when we die. Resurrection happens when our bodies are raised from the grave at the second coming of Christ.
But the world, the natural man has no faith or relationship with Christ and the Person of the Holy Spirit.
The natural man wants proof.
As humans who have not yet experienced being out of the body we also are curious.
