The purpose of being baptized into Christ is to destroy evil within me by accepting God's forgiveness. The baptized person who seeks to exploit God's goodness does not understand his or her baptism. He or she sought a way to escape evil, not a way to condone and continue evil. The baptized person places God in control of his or her life. He or she demonstrates a willing submission to God's rule by being obedient.
Law condemns ungodly behavior.
My determination combined with my will power cannot end my ungodly behavior. When I of myself seek to defeat my inner evil, I confirm the power of evil. Law is powerless to help me escape evil. Law reveals to me the truth that I am evil by confirming my failure to be pure and holy. Law exists to condemn, not to forgive.
