Abraham’s faith in God was strong. When God called him to forsake his family, friends and country, he obeyed and “went forth, not knowing whither he went.” When God promised to multiply his seed as the stars of heaven, he believed it, though childless. When, in his old age, God promised that he would still have a son by ninety-year-old Sarah, he believed it even though he had waited so long, seemingly in vain. When God promised to give his seed the land in which he had sojourned, he believed it, though all reason argued against it. When God asked him to offer in sacrifice the son born so late in life, the son upon whom all the promises depended, he obeyed, concluding that it must be God’s plan to raise him from the dead!
Such was Abraham’s faith in God! Three times this is emphasized in Romans 4 alone: He was “not weak in faith” (Ver. 19); he “staggered not at the promise of God through unbelief,” but was “strong in faith” (Ver. 20).
But it was not the strength of Abraham’s faith that saved him; it was the fact that the object of his faith was God (See again Gen. 15:6). He had placed his faith in the right Person. His faith became “strong” only because he had heard and believed God in the first place.
The simplest, humblest believer, who ever so feebly commits himself to God and His Word, is “justified freely by His grace through the redemption that is in Christ Jesus” (Rom. 3:24).
