We do not follow commandments; we live by faith through grace, believing in the resurrection of Jesus. being at the right hand of the Father.
we are in a better position than Jews who follow the Law. we are saved by the Grace of God through Christ Jesus.
Why do you think the Jews sacrificed their most valuable cattle if they thought they were saved by law obedience? They did not know it was a prophecy of Christ to do that, but they knew God required it.
Grace is an attribute of God, grace has always been. When sin entered the world, God's reaction was to give grace through blood given on the altar--in other words it was through the prophecy of Christ.
Psa_84:11 For the LORD God is a sun and shield: the LORD will give grace and glory: no good thing will he withhold from them that walk uprightly.
Gen_6:8 But Noah found grace in the eyes of the LORD.
Exo_33:17 And the LORD said unto Moses, I will do this thing also that thou hast spoken: for thou hast found grace in my sight, and I know thee by name.
Ezr_9:8 And now for a little space grace hath been shewed from the LORD our God, to leave us a remnant to escape, and to give us a nail in his holy place, that our God may lighten our eyes, and give us a little reviving in our bondage.
