4You have been severed from Christ, if you seek to be justified [that is, declared free of the guilt of sin and its penalty, and placed in right standing with God] through the Law; you have fallen from grace [for you have lost your grasp on God’s unmerited favor and blessing].
4Some of you think that God will accept you as right if you obey all the rules of his Law. But if you think that, you have made yourselves separate from Christ. You have turned away from God's grace.
