Imputation (James 2:23) and the Scripture was fulfilled which says, "and Abraham believed God, and it was reckoned to him as righteousness," and he was called the friend of God.
The phrase "reckoned to him as righteousness" is called imputation. God accounts righteousness to the believer in Christ, apart from law, through the divine act of Imputation (Rom 3:21). (The Biblicist)
