Putting Faith into Action
The author of Hebrews defines faith as “the substance of things hoped for, the evidence of things not seen” (Heb. 11:1). Faith fills the vacuum of hope. Hope, when coupled with faith, has substance, and substance is something rather than nothing. Faith also provides evidence for that which is not visible. Faith is not blind. Indeed far from being blind, it is both far-sighted and sharp-sighted. Its evidence rests not on speculation but on confidence in a God who sees what we cannot see. It rests on trust in the reliability of every promise that is uttered by God.
It is one thing to believe in God. It is quite another to believe God. Abraham believed God when He said He would show him a better country. He believed God again later when God dramatized His covenant promise in Genesis 15, and by this faith Abraham was counted righteous. He was justified by his faith.
That Abraham’s faith was genuine is seen in that he obeyed God by faith. True faith is always obedient faith. Abraham obeyed the call of God on his life—and he demonstrated this obedience when he “went out.” His faith issued in action.
