Ever since the world began humans have recognised a need for the existence of a Higher Power. The One True Higher Power has reached down to reveal Himself, not leaving it to nature to display shadows of the Almighty. In the old Testament He revealed Himself through shadow appearances projected through history. In the New Testament He broke into the world of humanity through Jesus Christ.
The Higher Power concept remains can seem vague and unsatisfactory, it begs broadening clarification that can only be unveiled through personal relationship with the saving Person of Jesus Christ.
Romans 1:20 There are things about God that people cannot see—his eternal power and all that makes him God. But since the beginning of the world, those things have been easy for people to understand. They are made clear in what God has made. So people have no excuse for the evil they do.
