If Jesus went to heaven that day when he died why did he tell Mary he hadn't yet ascended to his Father yet? John 20:17 Jesus said, "Do not hold on to me, for I have not yet ascended to the Father. Go instead to my brothers and tell them, 'I am ascending to my Father and your Father, to my God and your God.'"
Perhaps because he hadn't yet ascended to the father yet? because even though he lived as a man, that he didn't have the same role as a man that we do? from what I understand, He went down and preached to the souls in the underworld and emptied Abrahams bosom.
I believe Jesus was simply using comforting words towards the thief. Can you imagine Jesus saying, "After the general resurrection, which will occur after an indefinite period that only the Father knows, you shall be with me in Paradise." What the thief asked Jesus was to be remembered in His kingdom (Luke 23:42), and this is exactly what Jesus promised him, thus the dying man received peace and comfort. This is the great promise of the gospel—to be with Jesus forever.
With all due respect brother, and in brotherly love, please take this lightly, ok? But...really? Surely you jest brother. Just comforting words and no truth? I'm sorry, but I can't recall Jesus speaking like that to people.
Alright, let's say hypothetically John was taken to the third heaven. Does scripture say he stayed there and lived there? No. He received a vision and then went back to earth and lived out his days. In 2 Cor 12 did the man that was caught up in the third heaven stay there and live there? No. He heard the voice of God and then went back to earth and lived out his days. Paul even said, only God knows if he was in the body or out of the body. But the point is, is that both men did not remain in the third heaven to live there. 2 Cor 12:1-4 I must go on boasting. Although there is nothing to be gained, I will go on to visions and revelations from the Lord. 2I know a man in Christ who fourteen years ago was caught up to the third heaven. Whether it was in the body or out of the body I do not know—God knows. 3And I know that this man—whether in the body or apart from the body I do not know, but God knows— 4was caught up to paradise and heard inexpressible things, things that no one is permitted to tell.
