What is the purpose of Law in Scripture?
Law has been extant since the creation of the Angels as law is the arbiter of free will (Romans 2:15) and our conscience bears witness to that law infused within us at creation. The Covenant of Law is NOTHING new or special…it is simply a reiteration of the moral law written upon our heart as God codified His Law in stone and scratched it upon parchment through Moses… but this was given specifically to Jacob’s children as they were to be Holy as God is Holy and they were set apart for a special dispensation but NEVER was the Law a means to enteral life as the Law only defines sin void atonement (Romans 3:20).
From the beginning, mankind has found righteousness (a right standing) with God through FAITH (Hebrews 11), NOT works of the LAW because the Law only defines sin void any form of atonement (Romans 3:20). Jesus IS our atonement and Jesus kept the Law in perfection for us and by believing in Him as our Lord we can receive the imputation of Jesus’ righteousness into and over our life, forever, and enter into covenant relationship with the Father as clean vessels in the likeness of Jesus our Savior (2 Corinthians 5:21).
The Law, in the New Covenant, is written upon our heart and administered by the indwelling Holy Spirit and obedience to the Law of the Spirit is relevant SUBSEQUENT to our salvation…law cannot save…it simply points us to Jesus as our tutor and schoolmaster (Galatians 3:24) to lead us to repentance.
