Brethren, a pure and holy God cannot endure sin: he cannot have fellowship with it, or with those who are rendered unclean by it, for it would be inconsistent with his nature so to do. On the other hand, sinful men cannot have fellowship with God: their evil nature could not endure the fire of his holiness. Who among us shall dwell with the devouring fire? Who among us shall dwell with everlasting burnings? What is that devouring fire, and what are those everlasting burnings, but the justice and holiness of God?
Spurgeon Quote on Holiness Of God
