The struggle we have …

“The struggle we have with a holy God is rooted in the conflict between God’s righteousness and our unrighteousness. He is just, and we are unjust. This tension creates fear, hostility, and anger within us toward God. The unjust person does not desire the company of a just judge. We become fugitives, fleeing from the presence of the One whose glory can blind us and whose justice can condemn us. We are at war with Him unless or until we are justified. Only the justified person can be comfortable in the presence of a holy God.”
– from p.180 of “The Holiness of God” by R. C. Sproul.
