"For if Abraham were justified by the law of works, he hath to glory in himself; but not of God.  For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness.  Now to him who is justified by the law of works, is the reward reckoned, not of grace, but of debt.  But to him that seeketh not to be justified by the law of works, but believeth on him who justifieth not the ungodly, his faith is counted for righteousness. (Romans 4:2-5, Inspired Version)
