For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed. But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.
John 3:20-21

If we confess our sins He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
1 John 1:9
