“If anyone sees his brother sinning a sin which does not lead to death, he will ask, and He will give him life for those who commit sin not leading to death. There is sin leading to death. I do not say that he should pray about that. All unrighteousness is sin, and there is sin not leading to death.” 1 John 5: 16-17
John mentions here that there are sins that lead to death and sins that do not lead to death. That if a brother has been seen committing sin not leading to death then a brother should pray that God gives life to that person who commits a sin not leading to death. John does not indicate whether or not that person needs to repent first of that sin not leading to death before God “….will give him life for those who commit sin not leading to death.” This person could be having difficulty being aware of this sin seen by others or it may be some annoying habit they have not overcome so God in His great mercy will respond to the prayers of the faithful and excuse their brother because the sin does not merit death. Then he seems to indicate that if a brother has been seen sinning a sin leading to death, praying for that person to be forgiven for such sins is not something others should do. This does not mean that this person who commits sin leading to death should not be prayed for so that they come to their senses and truly repent. It just means that one should not pray to God to give this person life (forgiveness) when committing such sins because repentance is necessary for sins leading to death.
