Galatians 3:23-24

Now before faith came, we were kept in custody under the Law, [perpetually] imprisoned [in preparation] for the faith that was destined to be revealed, with the result that the Law has become our tutor and our disciplinarian to guide us to Christ, so that we may be justified [that is, declared free of the guilt of sin and its penalty, and placed in right standing with God] by faith.
