I have yet to see such a ridiculous scenario play out. We have a fornicating-single mother from our church who visits periodically and would welcome her back with open arms if she wanted to live a Christian life. She has said she just can’t and it’s too hard for her. I pray for her regularly to have a born again experience of Jesus’ free gift of salvation and freedom from sin - not of works, lest anyone should boast.
We had another who got into a marriage she shouldn’t have. Eventually he left her and was abusive and she returned to church. She raised her son in church but it was hard and he didn’t want to join nor be a Christian. She died in her 50s.
Her now adult son had a change of heart and over the course of a year, found salvation. I look forward to the day he and his mother can be reunited along with all of the other saints in the great cloud of witnesses. Are not there things worth living and dying for greater than having a postcard-perfect family photo?
