Matthew 13:49-50
So it will be at the end of the age. The angels will come out and separate the evil from the righteous and throw them into the fiery furnace. In that place there will be weeping and gnashing of teeth.

I say, therefore, with reverence and on the authority of the Word of God that God sees your sins no more; He sees the righteousness of Christ upon you. Lay hold of that.
Martyn Lloyd-Jones
