Proverb 28:13 "Forsake sin"

Proverbs 28:13 He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy.

Repent! It is the message that has been spoken throughout the Bible from beginning to end. It was the message of the prophets, John the Baptist, and especially Jesus Christ. Repent, turn away from sin, look unto God and His mercies. We are born again and live a regenerated life. This life cannot live in sin. It is repulsive and vile to the regenerated soul. A child of God can no longer digest and live on sin as without pain, conviction, and the discipline of God. We may believe the lies of this world enough to bite down into sin, we may even chew on it for a while, but those who are truly saved will vomit up sin and be broken in repentance.
Forsake sin. The Old Testament gives us a picture of what we must do with regards to sin and all that is sinful, the law stated that any people with leprosy were to be cast out no matter who they are. Whether family or friends, the least or the greatest, those who are unclean were to be put out from among the people. This is the same way we must treat our own sin. We repent of and forsake sin. In other words, we turn from our sin and confess it to God, and then we cast it, and all that would cause us to sin, completely out of our presence.
