Rom 4:22) “And therefore it was imputed to him for righteousness.” Understand, Abraham’s faith wasn’t righteousness; it was counted as righteousness. You see, the righteous act was God keeping His Word. It was the Lord Who then made the child Isaac to be conceived in the dead womb of Sarah. You are I are to obey, but remember, it is God Who brings the good to past despite our sin tainting the process.
