In Psalm 14, we begin to read:  The fool hath said in his heart, "(There is) no God!"

 "There is" is italicized.  These words do not appear in the original, but were placed there by the translators for easier reading in English.  

So, we may also read it as, No God (He does not exist for me) ..... Or perhaps No, God (decline His instruction and invitation) ... Isn't this always the way of man as he enters into sin?

For which we have the cure ....

KNOW GOD!
