Confession of Sin

There are three kinds of confession that must be considered :--
(1) Private Confession; for where the sin has been committed against God alone it need be confessed to no other but God. (1 John 1:9; Psalm 32:5.)
(2) Personal Confession; for where the sin has been committed against another it must be confessed not only to God but also to the one who has been wronged. Nor will there be any peace until the confession has been made and forgiveness sought. (Matthew 5:23,24.)
(3) Public Confession; for where the sin has been committed against the church, that is to say, the entire congregation, a class, organization or company of people the confession must be as public as the transgression. As long as iniquity among the people of God is covered over and unconfessed just so long will the Spirit of God be unable to bring about a Revival. Men must get right with each other in order to be right with God.
