"Why should I let you into my presence?"

A Christian, therefore, knows that if he were to die tonight and stand before God, and if God were to say, “Why should I let you into my presence?” the Christian would say, “You shouldn’t let me in. I have sinned and owe you a debt that I cannot pay back.” 

But he wouldn’t stop there. He would continue, “Yet because of your great promises and mercy, I depend on the blood of Jesus Christ shed as a substitute for me, paying my moral debt, satisfying your holy and righteous requirements, and removing your wrath against sin!”
