What does Psalm 14:2 mean?

This verse teaches that the Lord is transcendent. His perspective is greater than that of any person (Isaiah 55:8–9). Symbolically, David imagines God looking for someone with spiritual understanding, and finding none. He perceives that not one person has spiritual understanding, and no one seeks after the Lord. This is especially true in the case of those who reject God entirely (Psalm 14:1).

Genesis 6:5 portrays the Lord seeing the spiritual condition of humanity in the days of Noah. He "saw that the wickedness of man was great in the earth." Although God has revealed Himself in nature (Psalm 19:1), the person who lacks spiritual understanding (1 Corinthians 2:14) rejects this revelation. In Psalm 8:1 David exclaims, "O LORD, our Lord, how majestic is your name in all the earth!" Paul writes in Romans 1:19–20, "For what can be known about God is plain to [everyone], because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse."
