We must cease fighting against God and instead give our whole hearts to Him, holding nothing back. Then He can heal us. Then He can cleanse us from the venomous sting of sin.
Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted. But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed. (Isaiah 53:4-5)
Sin is like an injury to the spirit. If left untreated, it can also lead to more serious complications. Briefly discuss what some of those complications might be. (More serious sin, apostasy, or spiritual death.) We can take care of most of our spiritual injuries on our own. When a sin is grievous, someone with authority must help us. Ask: Who would that person be? (The bishop.)
