I came across this verse when reading the book of 1 John. I read it several times trying to make sense of it. I had to do some side research. Apparently it is a verse of which the meaning is widely debated.16If anyone sees his brother commit a sin that does not lead to death, he should pray and God will give him 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 he should pray about that. 17All wrongdoing is sin, and there is sin that does not lead to death.
Some believe that a sin that leads to death can be explained by the story of Ananias and Sapphira in Acts 5:1-10
This kind of sheds some light, but I still find the passage hard to understand. John states that there is "a sin that leads to death". It seems like he is talking about one specific sin. If so what is this sin?But a certain man named Ananias, with his wife Sapphira, sold a piece of property, 2 and kept back some of the price for himself, with his wife’s full knowledge, and bringing a portion of it, he laid it at the apostles’ feet. 3 But Peter said, “Ananias, why has Satan filled your heart to lie to the Holy Spirit...5 And as he heard these words, Ananias fell down and breathed his last; and great fear came upon all who heard of it . . .7 Now there elapsed an interval of about three hours, and his wife came in, not knowing what had happened. 8 And Peter responded to her, “Tell me whether you sold the land for such and such a price?� And she said, “Yes, that was the price.� 9 Then Peter said to her, “Why is it that you have agreed together to put the Spirit of the Lord to the test? Behold, the feet of those who have buried your husband are at the door, and they shall carry you out as well.� 10 And she fell immediately at his feet, and breathed her last,
He also states a confusing point on praying for those (or not praying) who have committed this sin(s). Why would we not pray for them? Because they are dead right after their sin?
