You seem to have missed a fundimental point. If you walk in openness and communion with the Lord in heaven why would you rebel against this?
In my view of the saved, being saved is confirmation that you have your priorities and consistency worked out, or at least you have started. But you then have the seed that fell on the path or on the rocky ground.
Imagine you die, the seed has born fruit in your heart, but it will not go too far, it will wither and die. Will you go to heaven, because you are saved, only to loose it again because you were too inconsistent.
Jesus does warn us, we are the branches, he is the vine. We perish without him. I think it unlikely you would walk away in eternity from who he is, but you do know in all relationships for love to work the possibility is always there.
Jesus the perfect man, stands before the Lord and says, do I have to drink from this cup? It is so hard, yet not my will but yours. Again the temptation in the desert. For this to be true, Jesus could have taken these points.
For those who say Jesus is the same as the Father, the temptation would have been meaningless, because he would have known and seen it all as it happened. Jesus was different, he did not know the time of the end of times. He did not know who would sit where on the ruling court etc.
Jesus appears to be the message of Gods nature made flesh, a living testimony of who God is, not a book, not an empty form, but a living man who can have relationships with the deciples.
Now for me a wonder is the Turin shroud. It is so strange the Lord wanted us to see his body, after the cross. But after reading and seeing the evidence, I think it is the real thing, given as a gift to us, as a testimony of His great love.
What is also obvious to me, is man lives in emnity to God, and if he saw Him face to face, would spit and revile him.
This world is such a balance between making a world view without God seems to make sense, as a real option, and the reality of Gods presence is everywhere, in all of life, one can but embrace it. For the Lord though, he gives freely to those he chooses, but how does he choose? If you could give eternal life, who would you give it to, and who is so living in their own hell and confusion, you would just want to release them from life?
The more I see of life the more I realise people are lost, stumbling around, hurting themselves, unaware of what drives them on. So ofcourse we could be kicked out of heaven, but that would be insane, and a literal contradiction of the love you have for the Lord.
