First John 5:16 – 17, however, seems to fall in another category. That passage does not speak of a sin that can never be forgiven, but rather about a sin that, if persisted in, will lead to death. This sin seems to involve the teaching of serious doctrinal error about Christ. In the context of asking in faith according to God’s will (1 John 5:14 – 15) John simply tells us that he does not say that we can pray in faith for God simply to forgive that sin unless the person repents — but he certainly does not prohibit praying that the heretical teachers would turn from their heresy and repent and thereby find forgiveness. Many people who teach serious doctrinal error have still not gone so far as to commit the unpardonable sin and bring on themselves the impossibility of repentance and faith by their own hardness of heart.
