"The main elements in "faith" in its relation to the invisible God, as distinct from "faith" in man, are especially brought out in the use of this noun and the corresponding verb, pisteuo; they are (1) a firm conviction, producing a full acknowledgement of God's revelation or truth, e.g., 2 Thess. 2:11,12; (2) a personal surrender to Him, John 1:12; (3) a conduct inspired by such surrender, 2 Cor. 5:7. Prominence is given to one or other of these elements according to the context. All this stands in contrast to belief in its purely natural exercise, which consists of an opinion held in good "faith" without necessary reference to its proof. The object of Abraham's "faith" was not God's promise (that was the occasion of its exercise); his "faith" rested on God Himself, Rom. 4:17,20,21."
