Hebrews 6:11-15

And we desire for each one of you to show the same diligence [all the way through] so as to realize and enjoy the full assurance of hope until the end, so that you will not be [spiritually] sluggish, but [will instead be] imitators of those who through faith [lean on God with absolute trust and confidence in Him and in His power] and by patient endurance [even when suffering] are [now] inheriting the promises. For when God made the promise to Abraham, He swore [an oath] by Himself, since He had no one greater by whom to swear, saying, “I WILL SURELY BLESS YOU AND I WILL SURELY MULTIPLY YOU.” [Gen 22:16, 17] And so, having patiently waited, he realized the promise [in the miraculous birth of Isaac, as a pledge of what was to come from God].
