The following is an excerpt from a message entitled The Sin Of Unbelief by C. H. Spurgeon.
"Unbelief, you see, has the Cain-mark upon its forehead. God hates it; God has dealt hard blows upon it; and God will ultimately crusth it. Unbelief dishonors God. Every other crime touches God's territory; but unbelief aims a blow at his divinity, impeaches his veracity, denies his goodness, blasphemes his attributes, maligns his character; therefore, God, of all things, hates first and chiefly, unbelief, wherever it is."
