Both atheist and Mormon were being treated for terminal cancer. The atheist received no blessing or prayer to God to be healed. The atheist lives and is cancer free after multiple treatments. The Mormon dies from cancer even after having a blessing and fellow Mormons prayers in supplication to Jesus to save him.<quoted text>
Totally depends. If he person committed these sins with the intention of repenting at the last minute, then he didn't really repent.
If he had no knowledge of Jesus or that his actions were sins, then he would most likely be forgiven, kinda like Ninevah. God gave them a second chance because they didn't know the things they did were evil. We are judged on our knowledge.
What reason would God allow the Mormon to die and the atheist to live?
