What does Proverbs 14:6 mean?

A "scoffer" (Proverbs 1:22) is someone who arrogantly mocks what they don't understand: the person who sneers at truth instead of learning from it. "Wisdom" is godly truth (Proverbs 1:7). In that sense, the idea of such a person "seeking" seems self-contradictory. It is, and this is the point being made. The "scoffer" looks to sources other than the Lord (Proverbs 9:10). Scoffers bypass the spiritual path to wisdom because they are proud (1 Corinthians 2:14). They think they can obtain wisdom by applying their mind to life's mysteries. They blindly accept what they want to hear (2 Timothy 4:3–4) and stubbornly ignore what they don't like (John 5:39–40), instead of submitting to what's real (Romans 1:18–20).

However, the wisdom of the world (Colossians 2:8) is no match for the wisdom of God, and scoffers learn the hard way that "God opposes the proud" (1 Peter 5:5). A man who respects God and submits to truth gains knowledge easily. Because he looks to the Lord for knowledge instead of to himself, he is open to what the Lord wants to teach him.
