“The fool says in his heart, ‘There is no God.’ They are corrupt, they do abominable deeds; there is none who does good.” —Psalm 14:1 (ESV)
A renown Cambridge mathematician is placed beside a Cajun swamp boat operator; which is wiser? A smart answer would be to ask “Where are they?” What is the setting? What is the test? If it is an academic setting, I’d wager the Cambridge professor; if the bayou, the Cajun. If it is the supermarket, we don’t have enough information.
What the fool fails to take into consideration is his setting. The fool fails to recognize ultimate reality. Where are we? In God’s creation. The fool says there is no God. The fool goes wrong at the foundational level.
“Fool” then is not so much an intellectual category as a moral one. It doesn’t take in less than the mind, but more. The fool says this in his heart. The heart here embraces more than the emotions. Biblically the heart is the core of man involving his intellect, emotions, and volition. This means that to determine if someone is a fool, you cannot just ask if they believe in God. You must analyze their life. What a person really says with their heart will be betrayed by their hands.
Professing atheists may be rare, but practical atheist are not an endangered species. It matters not if one says there is a god. If a person knows his addiction is unhealthy but persists in it he is foolish. Those who profess a god but live as though he were not are more foolish than those who try to delude themselves that God is not.
Some may consistently live as though a god were, but not the God. False religion, however sincere, is folly. Fools will find themselves to have been studying for the wrong test under the wrong instructor. They have wasted time studying Klingon for a Latin exam. They study Buddah, but Jesus is the answer. Folly is living in reference to an imaginary god. Wisdom is living unto the true God.
Perhaps it might be the Cajun who is the wise man and the professor who is the fool. Such are often the ways of God (1 Corinthians 1:26–31). This is true even when it comes to math. The simpleton who uses basic addition and subtraction to steward his money well for the kingdom of God is better with numbers than the professor who uses differential calculus for his own glory.
