S – This is why the promise is by faith, so that it may be according to grace, to guarantee it to all the descendants—not only to the one who is of the law but also to the one who is of Abraham’s faith. He is the father of us all.
Romans 4:16 CSB
O – Commentary:
Paul then drew his conclusion. Therefore (lit., “On account of this”) the promise comes by (ek, “out of”) faith so that it may be by (kata, “according to the standard of”) grace. Responding in faith to God’s promise is not meritorious, since the promise springs from His grace, His disposition of favor toward those who deserve His wrath. The human exercise of faith is simply the prerequisite response of trust in God and His promise. Since faith and grace go together, and since the promise is by grace, the promise can be received only by faith, not by the Law.
Another reason the promise is by faith is so that it may be guaranteed to all Abraham’s offspring, not only the Jews (those … of the Law) but to all who exercise faith in God. If the promise were fulfilled for those who keep the Law, then no Gentiles (or Jews either) could be saved! But this cannot be, because Abraham … is the father of us all, that is, all who believe.
“Romans,” in The Bible Knowledge Commentary: An Exposition of the Scriptures

R – Lord, I wholly put my faith in you. You are my Lord and Savior today. Let my thoughts, words, and actions align with your Word, Character and purposes for my life.
