Galatians 3:21

3:21 Is the law therefore opposed to the promises of God? Absolutely not! For if a law had been given that was able to give life, then righteousness would certainly have come by the law.

Numbers 23:19

23:19 God is not a man, that he should lie,

nor a human being, that he should change his mind.

Has he said, and will he not do it?

Or has he spoken, and will he not make it happen?

Romans 4:13-14

4:13 For the promise to Abraham or to his descendants that he would inherit the world was not fulfilled through the law, but through the righteousness that comes by faith. 4:14 For if they become heirs by the law, faith is empty and the promise is nullified.

Hebrews 6:13-18

6:13 Now when God made his promise to Abraham, since he could swear by no one greater, he swore by himself, 6:14 saying, “Surely I will bless you greatly and multiply your descendants abundantly.” 6:15 And so by persevering, Abraham inherited the promise. 6:16 For people swear by something greater than themselves, and the oath serves as a confirmation to end all dispute. 6:17 In the same way God wanted to demonstrate more clearly to the heirs of the promise that his purpose was unchangeable, and so he intervened with an oath, 6:18 so that we who have found refuge in him may find strong encouragement to hold fast to the hope set before us through two unchangeable things, since it is impossible for God to lie.
