Moral striving to become godly only keeps us slaves to sin.
For freedom Christ has set us free; stand firm therefore, and do not submit again to a yoke of slavery.
Look: I, Paul, say to you that if you accept circumcision, Christ will be of no advantage to you. I testify again to every man who accepts circumcision that he is obligated to keep the whole law. You are severed from Christ, you who would be justified by the law; you have fallen away from grace. ~ Gal 5.1-4
