Hi PilgrimPassingThru,
There is a difference between what Paul experienced by being caught up to heaven, where he received visions and revelations, where the thief that was crucified with Christ and died that same day. Paul's being caught up was temporary, whereas the thief's life was over and his spirit descended to Sheol/Hades with the Lord. Now according to Phil.1:23 and 2 Cor.5:6-9, once a believer dies, their spirit/soul departs from the body and immediately goes to be in the presence of the Lord. In opposition, those who die without Christ, their spirits/souls depart and go to Hades, i.e. the same place where the rich man went, where they will remain until the great white throne judgment.
