This episode spells out the consequences of "fooldom," where one prefers "foolish speculations" over the knowledge of God. Declaring in their hearts that "there is no God"(Psalm 14:1), the fool suppresses the available knowledge of God, speaking through creation and conscience. Just as nature abhors a vacuum, fools fill the void with futile speculations, ultimately aiming to "exchange the glory of the incorruptible God for an image in the form of corruptible man." (Romans 1:23) Self-serving idolatry then is the objective behind the rationalizations and actions of fools, who in varying degrees, resist the knowledge of God in pursuit of their own ends and glory. A common theme of future broadcasts is that "fools despise wisdom and instruction. (Proverbs 1:7) The underlying idolatry of the above "great exchange" anticipates hostile reactions to any who might correct the fool.
