Do not throw away your confidence; it will be richly rewarded. You need to persevere so that when you have done the will of God, you will receive what he has promised.
Hebrews 10:30-31
We know him who said, “It is mine to avenge; I will repay,” and again, “The Lord will judge his people.” It is a dreadful thing to fall into the hands of the living God.
Hebrews 12:28
Since we are receiving a kingdom that cannot be shaken, let us be thankful, and so worship God acceptably with reverence and awe.
