We are all familiar with the movie, “The Wizard of Oz.” If you recall, Dorthy and her dog Toto must journey across the land of Oz to request that the Great and Powerful Wizard of Oz help them get back home. Upon arrival at the gate of Emerald City, Dorthy says, “We want to see the Wizard!” To this the guard at the gate says, “The Wizard? But nobody can see the Great Oz! Nobody's ever seen the Great Oz! Even I've never seen him!” The idea was that the Wizard was far superior to all others, and therefore to know him was impossible, that is until he chose to reveal himself.
In the same way, it is impossible to know God due to his infinite superiority to us...that is until he chooses to reveal himself to us.
First, as our text above says, God's “greatness is unsearchable.” This sounds poetic, but it is also unfathomably true. Everything we can think of has a limit, that is except God. A greatness that is unsearchable has no limit. To be unsearchable is to be infinite. Psalm 147:5 says, “Great is our Lord, and abundant in power; his understanding is beyond measure.” Because we are finite and God is infinite we have no hope to fully understand God.
And isn't this the way we would want our God...incomprehensible.
Yes, but also no. It is true that to be God, by definition, He must be beyond our intellectual reach. If he was not, he would not be God, but something less than God. However, do we not also want to know this infinite being? Yes. There is something inside of us that cries out with a desire to know him. This is true for every human, the Calvinist and the atheist.
So how can we know an infinite God? He pulls back the curtain and reveals himself through His Word. This is the purpose of God's Word, to reveal Himself to us. As we read the unfolding of history as God has ordained it, first through the nation of Israel and then through His Son, we know God. This is the reason why the world is the way the world is, and this is why Christ had to come and die, so that we could know the incomprehensible God. As Jesus says in John 14:9, “Whoever has seen me has seen the Father.”
Therefore, if you want to know the unknowable God, open up the Bible and set your eyes upon Jesus.
