¹⁷ My point is this: the law, which came four hundred thirty years later, does not annul a covenant previously ratified by God, so as to nullify the promise.^(A)

³⁹ Yet all these, though they were commended for their faith, did not receive what was promised, ⁴⁰ since God had provided something better so that they would not, apart from us, be made perfect.^(A)

The Certainty of God’s Promise

¹³ When God made a promise to Abraham, because he had no one greater by whom to swear, he swore by himself,^{(A) 14} saying, “I will surely bless you and multiply you.” ¹⁵ And thus Abraham,^[a] having patiently endured, obtained the promise. ¹⁶ Humans, of course, swear by someone greater than themselves, and an oath given as confirmation puts an end to all dispute among them.^{(B) 17} In the same way, when God desired to show even more clearly to the heirs of the promise the unchangeable character of his purpose, he guaranteed it by an oath,^{(C) 18} so that through two unchangeable things, in which it is impossible that God would prove false, we who have taken refuge might be strongly encouraged to seize the hope set before us.^(D)

God’s Promise Realized through Faith

¹³ For the promise that he would inherit the world did not come to Abraham or to his descendants through the law but through the righteousness of faith.^{(A) 14} For if it is the adherents of the law who are to be the heirs, faith is null and the promise is void.

¹³ Then the Lord^[a] said to Abram, “Know this for certain, that your offspring shall be aliens in a land that is not theirs and shall be slaves there, and they shall be oppressed for four hundred years,^(A)
