Paul declared at Antioch (Act 13:39 ) And by him all that believe are justified from all things, from which ye could not be justified by the law of Moses.
I have been justified by all things spelled out in the mosaic law( the Ten Commandments inclusive). Wow! My sins are forgiven. Now I swing free in victory over sin, sickness, and the calamities of this world. My sins are forgiven it is nowadays of heaven on earth. I am a candidate for the REVAYAH! Glory! Nothing can change this!
Gal 3:17 (17-18) This means that the covenant between God and Abraham was fulfilled in Messiah and cannot be altered.
