Berean Standard Bible (BSB)
Therefore, the promise comes by faith, so that it may rest on grace and may be guaranteed to all Abraham’s offspring—not only to those who are of the law, but also to those who are of the faith of Abraham. He is the father of us all.
World English Bible (WEB)
For this cause it is of faith, that it may be according to grace, to the end that the promise may be sure to all the seed, not to that only which is of the law, but to that also which is of the faith of Abraham, who is the father of us all.
Strong's King James
Therefore{G1223}{G5124} it is of{G1537} faith{G4102}, that{G2443} it might be by{G2596} grace{G5485}; to the end{G1519} the promise{G1860} might be{G1511}{(G5750)} sure{G949} to all{G3956} the seed{G4690}; not{G3756} to that only{G3440} which is of{G1537} the law{G3551}, but{G235} to that also{G2532} which is of{G1537} the faith{G4102} of Abraham{G11}; who{G3739} is{G2076}{(G5748)} the father{G3962} of us{G2257} all{G3956},

(16) So because of this reason, accordingly from believing-faith and in order with favourable-grace. For the promise-vow will be firmly enforced for all the seed, not only those from The Torah-Law but those also from the believing-faith of Avraham, being father of us all.
