...and it is too late to pray for this man.

For God NOTHING is impossible (Jeremiah 32:27; Luke 1:37; Matthew 19:26). God exists outside of linear time, which He created. He has no such constraints. I put my trust in HIM and pray for the entire family. Let us praise God for His Truth and His great mercy. We rejoice in His goodness!
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.
