Jesus did not allow the rich man's request for having his family on earth to be warned about hell. We do see instances where people claim to have been in hell and then returning with a message just to forgive.
My question is whom to believe - Jesus or the NDE travellers? I also once died and saw things but it differs from these who say "forgive, regardless."
Let us sit at the feet of Jesus and hear what He says:
Matthew 18:15 “If your brother sins against you, go, show him his fault between you and him alone. If he listens to you, you have gained back your brother.
Matthew 18:16 But if he doesn’t listen, take one or two more with you, that at the mouth of two or three witnesses every word may be established.
Matthew 18:17 If he refuses to listen to them, tell it to the assembly. If he refuses to hear the assembly also, let him be to you as a Gentile or a tax collector.
Matthew 18:18 Most certainly I tell you, whatever things you bind on earth will have been bound in heaven, and whatever things you release on earth will have been released in heaven.
