The fool has said in his heart, “There is no God.”
Psalms 14:1
For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men who suppress the truth in unrighteousness, because that which is known about God is evident within them, for God has made it evident to them. For since the creation of the world His invisible attributes, His eternal power and divine nature have been clearly seen being understood through what has been made, so that they are without excuse.
Romans 1:18-20
King David said it well, only a fool would say there is no God.
We are not left to wonder about God’s existence, we are presented with the evidence of His existence.
Paul in his letter to the Romans explains that God has revealed Himself to all men. God created the universe and all that is in it. If man simply looks at a new baby, he can see that only the hand of a divine God could create something so wonderful.
Only a fool having seen the universe could deny the creator of it all - the strong, powerful, true God.
