John 1:17 note 1
171 The law makes demands on man according to what God is; grace supplies man with what God is to meet what God demands. The law, at most, was only a testimony of what God is (Exo. 25:21), but reality is the realization of what God is. No man can partake of God through the law, but grace enables man to enjoy God. Reality is God realized by man, and grace is God enjoyed by man.
