It is very liberating to remember that God knows we can't do what He asks of us but because He is so loving and gracious we should at least try to by His guidance and power. The OT Law was fulfilled in Christ and we have been made free.
I wondered why, last year, when I was trying to be a better Christian... I was so stressed trying to remember the Law...
I was trying to please God, and ended up exhausted.
Thank Heavens for Jesus!
Faith of works is just wearing out the flesh unless we are working for faith. I am glad you discovered this truth early on and fell into surrender to Him. Some people never figure that out.
