There are something that are impossible to my God, the God of the Bible:
1. He cannot sin.
2. He cannot abide sin in his presence.
3. The soul of the human whom God has not saved before his/her physical death will go to Sheol=Hades=Hell, and after the judgment, into the Lake of Fire forever. The righteousness of The God will not permit Him to save a human who can no longer repent.
I hate to tell you this, but your outlook on this issue is fatally flawed, and I mean fatally.
Respectfully --
Then why does the Bible say that “For God nothing is impossible?” See Luke 1:37
...or Matt 19:36 - “Jesus looked at them and said, “With man this is impossible, but with God all things are possible.”
Jeremiah 32:27 Behold, I am the Lord, the God of all flesh. Is there anything too hard for me?
PS We were NOT discussing that which goes against the very nature of God.
