Only fools say in their hearts, “There is no God.” They are corrupt, and their actions are evil; not one of them does good! Psalm 53:1 (NLT)
According to this Scripture which is actually repeated twice, the first time being Psalm 14:1, foolishness is disregarding and denying God. All of creation screams the existence of a creator who is God Romans 1:19-20. To deny the existence of God is to deny your very own existence because God created you in His own image and likeness. How foolish for a branch to deny the tree that carries and sustains it. In God you live, move, and have your being Acts 17:28.You may not directly and outright say there’s no God but if in your daily life and business God has no say so it’s also disregarding or denying God.In Ephesians 5:15,17 we are cautioned not to walk as fools but find out the will of God.Don’t act foolishly, acknowledge God in all your plans and decisions.
