If you see a fellow believer sinning in a way that does not lead to death, you should pray, and God will give that person life. But there is a sin that leads to death, and I am not saying you should pray for those who commit it. (I John 5:16)
We do not know what the “sin that leads to death” actually is. However, we do see it as so severe in John’s mind, that he wonders a loud if it’s even worth praying over. This individual evidently is so hell-bent on his own destruction that John sees that perhaps prayer energies would be better spent on someone else. How does one make that judgment? Without more explanation how is this passage helpful? Is this a descriptor of the modern-day terrorist? The modern-day pedophile? I hope not, because this sinning person is referred to as “a brother”. Is this then about someone who would claim to be Christian but yet is so decidedly evil? In this epistle John is particularly hard on 2 types of people
Are these people so far gone into their own destructive hate and delusions about the person of Jesus that they are beyond the point of return? Is this what John is talking about? I wonder if it’s even possible to know for sure.
What is the lesson for us? Is it that some sins are more severe than others? Yes, certainly that is one point, but I don’t think that’s the main point. The Christian must take all sin very seriously.
We know that God’s children do not make a practice of sinning (Vs 18)
The Christian person will run from and resist all sin at all costs. The Christian life will manifest itself in loving actions and attitudes toward other humans.
If we don’t love people we can see, how can we love God, whom we cannot see? (4:20)
If it does not something is “deathly” wrong.
