Romans 4:22

22.And it was therefore imputed, (149) etc. It becomes now more clear, how and in what manner faith brought righteousness to Abraham; and that was, because he, leaning on God’s word, rejected not the promised favor. And this connection of faith with the word ought to be well understood and carefully remembered; for faith can bring us nothing more than what it receives from the word. Hence he does not become immediately just, who is imbued only with a general and confused idea that God is true, except he reposes on the promise of his favor.

“It is most true, as Paul says to the Romans, that by faith Abraham was justified, and not by obedience: but it is just as true what he says to the Hebrews, that it was by faith that Abraham obeyed.” — [Chalmers ].
