Nothing of the OT has ended but as believers, we have died to that relationship and live unto the living God in a living relationship.
Therefore, my brethren, you also have become dead to the law through the body of Christ, that you may be married to another—to Him who was raised from the dead, that we should bear fruit to God. (Rom 7:4)
For I through the law died to the law that I might live to God. I have been crucified with Christ; it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself for me. (Gal 2:19-20)

Galatians 2:16 (NASB) nevertheless knowing that a man is not justified by the works of the Law but through faith in Christ Jesus, even we have believed in Christ Jesus, so that we may be justified by faith in Christ and not by the works of the Law; since by the works of the Law no flesh will be justified.
Galatians 3:11 (NASB) Now that no one is justified by the Law before God is evident; for, "THE RIGHTEOUS MAN SHALL LIVE BY FAITH."
Galatians 3:24 (NASB) Therefore the Law has become our tutor to lead us to Christ, so that we may be justified by faith.
