What is Man's Greatest Failure?

Psalms 14

Chapter breakdown:
vs. 1-3: Mankind is corrupt apart from God
vs. 4-6: God is righteous
vs. 7: Jesus brings peace

1-3:
A fool says there is no God.
Deuteronomy 32:15 - in this verse, fool means “lightly esteemed”
Isaiah 64:6 - in this verse, fool means to “fade”

A fool is willfully morally deficient, but can be extremely intelligent. They reject God.
Jeremiah 9:23 - wise men should not glory in his wisdom
Jeremiah 10:10 - the Lord is the true God, everlasting King.

A fool is a man who rejects God, denies Creation.
Romans 1:18-20 - a fool holds truth in unrighteousness. God shows us truth, but they turn it into a lie.
Creation is clearly seen, they are without excuse. They have a foolish heart, they became fools when they reject what they know already true.

4:
All people know there is a God.
First Samuel 3:13 - God will hold people accountable for what they know. Every person has a knowledge of God.

5:
Saying no to God, will bring them in great fear because of their judgment to come from God.

6:
Fools shame the poor who call on God.

7:
Jesus will come and bring peace. Israel will be there.
