In an increasingly scientific and technology-driven world, our culture is becoming more and more unfamiliar with mystery and awe. We are uncomfortable with grappling with what cannot be fully explained- that which is larger than us- certainly when it comes to the subject of God. It's possible for Christians, who profess to know God, to spend very little time considering His awesomeness- that His mind, ways, and being are often beyond our ability to explain- and because of that, we should offer Him our humble praise, and pursue what we can know of Him in this life. A.W. Tozer writes poignantly of this issue more than a half-century ago:
"The human mind, being created, has an understandable uneasiness about the Uncreated. We do not find it comfortable to allow for the presence of One who is wholly outside of the circle of our familiar knowledge. We tend to be disquieted by the thought of One who does not account to us for His being, who is responsible to no one, who is self-existent, self-independent, and self-sufficient.
Philosophy and science have not always been friendly toward the idea of God, the reason being that they are dedicated to the task of accounting for things and are impatient with anything that refuses to give an account of itself. The philosopher and the scientist will admit that there is much that they do not know; but that is quite another thing from admitting that there is something that they can never know, which indeed they have no technique for discovering. To admit that there is One who lies beyond us, who exists outside of all our categories, who will not be dismissed with a name, who will not appear before the bar of our reason, nor submit to our curious inquiries: this requires a great deal of humility, more than most of us possess, so we save face by thinking God down to our level, or at least down to where we can manage Him. Yet how He eludes us! For He is everywhere while He is nowhere, for “where” has to do with matter and space, and God is independent of both. He is unaffected by time or motion, is wholly self-dependent and owes nothing to the worlds His hands have made...
It is not a cheerful thought that millions of us who live in a land of Bibles, who belong to churches and labor to promote the Christian religion, may yet pass our whole lives on this earth without once having thought or tried to think seriously about the being of God. Few of us have let our hearts gaze in wonder at the I AM, the self-existent Self back of which no creature can think. Such thoughts are too painful for us. We prefer to think where it will do more good—about how to build a better mousetrap, for instance, or how to make two blades of grass grow where one grew before. And for this we are now paying a too heavy price in the secularization of our religion and the decay of our inner lives.
Perhaps some sincere but puzzled Christian may at this juncture wish to inquire about the practicality of such concepts as I am trying to set forth here. "What bearing does this have on my life?" he may ask. "What possible meaning can the self-existence of God have for me and others like me in a world such as this and in times such as these?"
To this I reply that, because we are the handiwork of God, it follows that all our problems and their solutions are theological. Some knowledge of what kind of God it is that operates the universe is indispensable to a sound philosophy of life and a sane outlook on the world scene...
We can never know who or what we are till we know at least something of what God is. For this reason the self-existence of God is not a wisp of dry doctrine, academic and remote; it is in fact as near as our breath and as practical as the latest surgical technique."
