Was reckoned to Abraham
διὸ καὶ ἐλογίσθη αὐτῷ εἰς δικαιοσύνην.
Paul said that therefore, his faith was reckoned or credited (διὸ καὶ ἐλογίσθη) to Abraham (αὐτῷ) as righteousness (εἰς δικαιοσύνην). Paul said that because of his faith in God, Abraham was considered or credited as being righteous. No question about it, it was the faith of Abraham that made him a righteousness man. Do you consider yourself righteous?
