I love the simplicity and honesty of this question.

Confrontation carries the risk of offending someone. There is no way to truthfully speak the truth to someone without the possibility of offending them. If the truth needs to be told, we must risk ruffling somebody’s pride. Sometimes people are offended by the truth. Sometimes our approach or attitude creates the offense.

I could never assume to know the full reason why the specific person you care so much about is still not responsive to God’s grace. I also would fall short of explaining why it appears that God has not answered your prayers. That said, here are some thoughts I have wondered about on this topic.
