And the men turned their faces from thence, and went toward Sodom: but Abraham stood yet before the LORD.  And Abraham drew near, and said, “Wilt Thou also destroy the righteous with the wicked?  Peradventure there be fifty righteous within the city: wilt Thou also destroy and not spare the place for the fifty righteous that are therein?  That be far from Thee to do after this manner, to slay the righteous with the wicked: and that the righteous should be as the wicked, that be far from Thee: Shall not the Judge of all the earth do right?”  And the LORD said, “If I find in Sodom fifty righteous within the city, then I will spare all the place for their sakes.”
Genesis 18:22-26

Of course, the Judge of all the earth will do right. He can do no wrong. He knows how to deliver the righteous from the judgment of the unrighteous.

All who come to God through the cross of Jesus Christ, shall be cleansed, forgiven, and given the righteousness of Christ.
