“If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.”
1 John 1:9

Confess from the Greek has two meanings – to acknowledge or agree, and to revere or worship. Its a commitment to the first that leads to a continuation of the second. God is faithful and just regardless. When we acknowledge and agree to our sin, we receive forgiveness and purification that grants us a richly rewarding worship.
