Is Abraham in Paradise now?
It appears from 2 Cor. 12:4 and Ephesians 4:7-8 that when Jesus ascended into heaven He took the believers who had died before the cross with Him. If so He was essentially relocating Paradise into heaven, in which case Abraham would be in heaven today.
Paul made reference to the fact that if he died He would be with the Lord. He was talking about his spirit leaving his body behind and going directly to heaven (2 Cor. 5:8). From this we conclude that the spirits of all believers who die now go directly to be with the Lord and confirms the belief that Paradise has been moved to heaven.
