Hebrews 6:11-15

But we long to see you passionately advance until the end and you find your hope fulfilled. So don’t allow your hearts to grow dull or lose your enthusiasm, but follow the example of those who fully received what God has promised because of their strong faith and patient endurance. Now when God made a promise to Abraham, since there was no one greater than himself, he swore an oath on his own integrity to keep the promise as sure as God exists! So he said, “Have no doubt, I promise to bless you over and over, and give you a son and multiply you without measure!” So Abraham waited patiently in faith and succeeded in seeing the promise fulfilled.
