“For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness.”
King James Version (KJV)
4:3 Abraham believed God - That promise of God concerning the numerousness of his seed, #Gen 15:5|,7; but especially the promise concerning Christ, #Gen 12:3|, through whom all nations should be blessed. And it was imputed to him for righteousness - God accepted him as if he had been altogether righteous. #Gen 15:6|.
Ro 4:3 For what saith the scripture? The passage quoted is found in Ge 15:6, and is quoted three times in the New Testament--here, and in Ga 3:6 and in Jas 2:23. God promised an heir to Abraham, and, although it seemed contrary to nature, he believed the promise. His faith in the promise was counted unto him for righteousness. It was the ground of his acceptance with God. His faith was a trusting faith, which contained in it the element of obedience. No other faith justifies.
