Hebrews 10:23, 35-36

Let us seize and hold tightly the confession of our hope without wavering, for He who promised is reliable and trustworthy and faithful [to His word]

Do not, therefore, fling away your [fearless] confidence, for it has a glorious and great reward. For you have need of patient endurance [to bear up under difficult circumstances without compromising], so that when you have carried out the will of God, you may receive and enjoy to the full what is promised.
