The consummate April Fool!

(Charles Spurgeon)

"The heavens declare the glory of God; the skies proclaim the work of His hands. Day after day they pour forth speech; night after night they display knowledge. There is no speech or language where their voice is not heard. Their voice goes out into all the earth, their words to the ends of the world!" Psalm 19:1-4

He who looks up to the heavens and then writes himself down as an atheist, brands himself at the same moment as an idiot or a liar! The Atheist is the fool preeminently, and a fool universally! To say there is no God is . . .
  to belie the plainest evidence, which is obstinacy;
  to oppose the common consent of mankind, which is stupidity;
  to stifle consciousness, which is madness.

If the sinner could by his atheism destroy the God whom he hates, there would be some sense, although much wickedness, in his infidelity. But as denying the existence of fire does not prevent its burning a man who is in it — so doubting the existence of God will not stop the omnipotent Judge from destroying the rebel who breaks His laws. Nay, this atheism is a crime which much provokes God, and will bring down terrible vengeance on the fool who indulges it!

"The fool says in his heart: There is no God!" Psalm 14:1

The world we live in, is a world of fools! (John Jamieson)

Who in the world is a greater fool, a more ignorant, wretched person — than he who is an atheist? (Jeremy Taylor)

"Take heed, you senseless ones among the people; you fools, when will you become wise?" Psalm 94:8
