God will hold the unjust accountable for their sins

Revelation 22:11-12

He who acts unjustly, let him act unjustly still. He who is filthy, let him be filthy still. He who is righteous, let him do righteousness still. He who is holy, let him be holy still. Behold, I come quickly. My reward is with me, to repay to each man according to his work.
