Grace means that God does something for me; law means that I do something for God. God has certain holy and righteous demands which he places upon me: that is law. Now if law means that God requires something of me for their fulfillment, then deliverance from law means he no longer requires that from me, but himself provides it.
Watchman NeeWhen one tries to increase his knowledge by doing mental gymnastics over books without waiting upon God and looking to the guidance of the Holy Spirit, his soul is plainly in full swing. This will deplete his spiritual life. Because the fall of man was occasioned by seeking knowledge, God uses the foolishness of the cross to "destroy the wisdom of the wise.
Watchman NeeWhen a believer has crossed into the domain of the spiritual he daily ought to maintain a combat attitude in his spirit, praying therewith for the overthrow of all the works of Satan done through the evil powers.
