God wants to be known—not figured out. The Bible says God reveals Himself to everyone through His creation. But there is special revelation to those born of His Spirit (1 Cor. 2:14). And that is the ‘key’ to knowing Him. The “natural” man cannot know God—only the “spiritual” man can. God will not be known by intellect and intelligence. In fact, Jesus said God hides Himself from those who think they are wise and clever but reveals Himself to those who are childlike (Lk 10:21).
Maybe it’s because natural men cannot know God that they try so hard to “figure Him out.” But to that God says: “You thought I was like you, but as the heavens are higher than the earth, so are My ways higher than your ways and My thoughts than your thoughts” (Ps. 51:25; Is. 55:8-9). Albert Einstein, an avowed agnostic, once said: "In my opinion the idea of a personal God is a childlike one." At least he got that right!
