1 John 5 -16 :- If you see any brother or sister commit a sin that does not lead to death, you should pray and God will give them life. I refer to those whose sin does not lead to death. There is a sin that leads to death. I am not saying that you should pray about that.
I recently had a mature brother share in my Church on the meaning of Sin leading to death. It was very prophetic. I never thought this sin was that serious and could lead to death.
Here John is asking believers to not pray for a fellow brother who is committing a sin leading to death. So whatever that sin is, it is does not demand prayer from fellow brothers.
1 John 4:20- If anyone says, "I love God,” but hates his brother, he is a liar. For anyone who does not love his brother, whom he has seen, cannot love God, whom he has not seen.
1 John 3:15 :- Everyone who hates his brother is a murderer, and you know that eternal life does not reside in a murderer.
So the sin that leads to death is a sin of hatred towards a fellow brother in Christ. John says he does not have eternal life. He might have had eternal life before, but not now. So when we find a fellow brother in Christ hating us, we should not even pray for this brother.
Where did John learn it from? He learnt it from Jesus. Jesus did not pray for Judas. Peter committed a serious sin of denying Jesus. But Jesus still prayed for him that his faith should not fail. But there is no record of Jesus praying for Judas after the sin to betray Jesus entered Judas. In fact Jesus asked him to do it quickly!
It is easy to imagine that we are good and never hate another brother in Christ, without being part of a local body of believers. But once you get into a local body and have to work with brothers who are different from you, then only you will be tested in this sin. I believe due to this hatred, many have already withdrawn from local body of believers. It is easy to love brothers in Christ who are persecuted in distant nation. But difficult to fellowship in a committed relation with a body of believers.
