Hebrews 10:33

For we know him who said, “Vengeance belongs to me. I will repay,” says the Lord. Again, “The Lord will judge his people.”

It is a fearful thing to fall into the hands of the living God.

But remember the former days, in which, after you were enlightened, you endured a great struggle with sufferings:

For you both had compassion on me in my chains and joyfully accepted the plundering of your possessions, knowing that you have for yourselves a better possession and an enduring one in the heavens.

Therefore don’t throw away your boldness, which has a great reward.

For you need endurance so that, having done the will of God, you may receive the promise.
