A Faithful Witness
It is not the opposition of the world that most endangers the church of Christ. It is the evil cherished in the hearts of believers that works their most grievous disaster and most surely retards the progress of God's cause.
As a witness for Christ, John entered into no controversy, no wearisome contention. He declared what he knew, what he had seen and heard.
But true charity is too pure to cover an unconfessed sin. While we are to love the souls for whom Christ died, we are to make no compromise with evil. We are not to unite with the rebellious and call this charity.
The apostle teaches that while we should manifest Christian courtesy we are authorized to deal in plain terms with sin and sinners; that this is not inconsistent with true charity.
He that confesseth and forsaketh his sin shall have mercy.
