In multiple places in the bible, we hear the Lord tell us He will write his law upon our hearts perhaps most clearly emphasized in Jeremiah,. “Deep within them I will plant my Law, writing it on their hearts.”
My question today is, is this to be understood as having begun with the New Covenant? Prior, in times of the Old Covenants which Israel would mess up time and time again, the Laws instilled by God.
Are we to take this literally, that God somehow, mystically changed our hearts such that our very own conscience (when properly formed) entails us to know better the Will of God? Where prior to the New Covenant, in order for one to do “good” he/she was less inclined to know the Will of God and therefore was more reliant to the written Law.
Hope I am being clear. This question is really a stepping stone for more questioning in my heart and mind, but this is at the root.
