Hebrews 6:12-15

6:12 so that you may not be sluggish, but imitators of those who through faith and perseverance inherit the promises.

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.
