Good Day,
A man like Abraham whose Faith is counted to them as "righteousness"
Is this blessing then only for the circumcised, or also for the uncircumcised? For we say that faith was counted to Abraham as righteousness.
That is why it depends on faith, in order that the promise may rest on grace and be guaranteed to all his offspring—not only to the adherent of the law but also to the one who shares the faith of Abraham, who is the father of us all, as it is written, “I have made you the father of many nations”—in the presence of the God in whom he believed, who gives life to the dead and calls into existence the things that do not exist.
John Gill notes:
Blessed is the man to whom the Lord will not impute sin. As he does not to those whom he justifies in Christ, and by his righteousness; for the sins of such he has imputed to his Son, as their surety; and he has bore them, took them away, having made full satisfaction for them; so that these persons will never be charged with them: they now appear before the throne without fault, and are blameless and irreproveable in the sight of God, and therefore must be eternally happy; for he will never think of their sins any more to their hurt; he will remember them no more; he "will never reckon them to them", but acquit them from them, justify and accept them; wherefore they must be secure from wrath and condemnation, enjoy much peace and comfort now, and be happy hereafter.
In Him,
Bill
