If anyone observes a fellow believer habitually sinning in a way that doesn’t lead to death, you should keep interceding in prayer that God will give that person life. Now, there is a sin that leads to death, and I’m not encouraging you to pray for those who commit it.
If anyone speaks evil of me, the Son of Man, that one can be forgiven. But if anyone speaks scornfully against the Holy Spirit, it will never be forgiven.
