When men follow after vanity, they themselves become vain. An individual must make a conscious decision to turn from walking after the Lord to pursue vanity (Jeremiah 2:5). Those who follow after vanity are void of understanding (Proverbs 12:11) and end up in poverty (Proverbs 28:19), sometimes both spiritually and physically. David expressed his concern in this area when he said, “I have not sat with vain persons” (Psalm 26:4). He knew the danger of following vanity and declared that he refused even to sit with vain persons. In Psalm 119:37, the penman pleaded with the Lord for help in turning away his eyes from beholding vanity. God desires and wills for the saints of God to cease from following after vanity.
People base decisions on different things: some make choices based on their feelings, others by chance or counsel, and some by knowledge. A prudent man does not trust his feelings for making the right choices lest he be led astray. He does not believe in chance and verifies counsel before choosing his direction. When he decides, he only trusts one foundation; and that is knowledge that comes from God. His certainty for decisions only comes from facts that he can verify. Proverbs has much to say about the association of knowledge and prudence. “A prudent man concealeth knowledge”(Proverbs 12:23); “the prudent are crowned with knowledge” (Proverbs 14:18); “The heart of the prudent getteth knowledge” (Proverbs 18:15). A prudent man demands knowledge and seeks after it with his whole heart. By doing so, he avoids the terrible fate of the fools and the simple.
