The OT Law, today
Gal3:23-25 But before faith came, we were under the law, shut up unto the faith which should afterwards be revealed. Wherefor the law was our schoolmaster to bring us to Christ, that we might be justified by faith. But after that faith is come, we are no longer under a schoolmaster.
Mt5:18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
The law of the Old Covenant is in effect on everyone that has died with Jesus and has been born of the Spirit. For those who turn to the Lord in repentance and faith, the law is superseeded by the New Covenant. So that, (Rom8:2) the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.
