Christianity’s most staggering claim isn’t that God exists (all religions say that); it’s that He communicates. We call this revelation, the act by which God reveals Himself to the world. For if man is to know God, it can only because God reveals Himself by speaking. It is through God’s voice that we possess the knowledge of God.
This, of course, is what helps distinguish Christianity from every other major world religion. How can we be sure that the God of Christianity is true? Because the God of Christianity speaks to us in ways that are meaningful.
Christian theology teaches that God’s voice can be heard both directly as well as indirectly. We call these distinct categories “General” (or “natural”) revelation and “Specific” (or “special”) revelation. We’ll start today with general revelation—the voice of God as heard in creation.
NATURE REVEALS GOD’S PRESENCE
David writes that “the heavens declare the glory of God, and the sky above proclaims his handiwork” (Psalm 19:1). Elsewhere in the psalms, we read a song of praise to the God who “set the earth on its foundations so that it should never be moved… You covered it with the deep as with a garment; the waters stood above the mountains” (Psalm 104:5-6). The universe and all that’s in it point toward a Creator. Why else is there something instead of nothing?
One of the most fascinating things that we often take for granted is that the universe is an orderly place. For centuries, men like Galileo and Newton understood this to be the fingerprints of a God who is Himself orderly and intelligible. For instance, Sir Isaac Newton famously wrote that “this most beautiful system of the sun, planets and comets, could only proceed from the counsel and dominion of an intelligent and powerful being.” And because God exists as a community of Father, Son, and Spirit, it should come as no surprise that the diversity of the Godhead would be reflected in the diversity in the universe. “All that diversity of natural things,” wrote Newton, “could arise from nothing but the ideas and will of a Being, necessarily existing.”
In his letter to the Romans, Paul writes that God’s general revelation only solidifies the guilt of those who refuse to submit to God’s authority:
18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. 19 For what can be known about God is plain to them, because God has shown it to them. 20 For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. (Romans 1:18-20)
Evolution, of course, has been long assumed to replace any explanatory need for God. According to Oxford professor Richard Dawkins, “Darwin made it possible to be an intellectually satisfied atheist.” If you know me well, you know that I studied science as an undergraduate student—specifically the field of biochemistry. Biochemistry and molecular biology reveal a hidden world that evolution alone has yet to fully explain. My suggestion is twofold: that the presence of complexity and the presence of information hint at the presence of a Creator.
- The presence of complexity
I can still vividly remember turning the page in my cell biology textbook and seeing an image of the interior of the cell membrane. Now, to be clear, Darwin knew shockingly little about the cell. Technology had only allowed him to understand the cell as the simplest of parts; the years after him would reveal that each of our body’s cells is a complex network of molecular machinery. The diagram in my textbook showed a basic molecular “circuit:” a series of proteins embedded in the membrane of your average cell. The pieces were complex, and could only work together if they came together.
In his book Darwin’s Black Box, Michael J. Behem compares this to a mousetrap. Sure, we can pull the mousetrap apart and find a use for each of the parts. The base might make a nice paperweight; the clamp could maybe be used as a fishhook or something. But the mousetrap can only work if all the pieces come together at once—and in the right arrangement. And each cell is massively more complex than the average mousetrap. How could the pieces have evolved separately and then come together just right to make our cells function? The answer, Behe suggests, is that perhaps this complexity hints at a designer.
- The presence of information
My mother recently got one of those ancestry DNA kits. They compare your DNA to that of a database to trace your family relations. This only works because your DNA contains such a massive library of information about you. Everything about us, from our eye color to our shoe size is embedded in long, molecular code. For DNA consists only as a long chain of four molecules, represented by the letters A, T, C, and G. So if you were to write out your DNA code, it might look something like: “ATCCAGGGTTCCCAATTC…” and so on. Francis Collins, former head of the human genome project, tells us that your DNA code is so long, that if you were to print it out on standard printer paper using standard font, the stack of pages would be taller than the Washington’s monument in D.C. What’s more staggering is that if a single letter is out of place, this can result in genetic disease.
Years ago William Paley suggested that if you found a watch on a beach, the complexity of its design would suggest the existence of a Watchmaker. But what if you found an entire library of books? Surely the information in our DNA points toward a higher intelligence.
NATURE REVEALS GOD’S LOVE
But we must also not neglect the way that creation points toward the loving character of God. Returning to Psalm 104, we read:
10 You make springs gush forth in the valleys;
they flow between the hills;
11 they give drink to every beast of the field;
the wild donkeys quench their thirst.
12 Beside them the birds of the heavens dwell;
they sing among the branches.
13 From your lofty abode you water the mountains;
the earth is satisfied with the fruit of your work.
14 You cause the grass to grow for the livestock
and plants for man to cultivate,
that he may bring forth food from the earth
15 and wine to gladden the heart of man,
oil to make his face shine
and bread to strengthen man’s heart. (Psalm 104:10-15)
Even Jesus points to the example of the birds and lilies as evidence of God’s loving care (Luke 12:24-27). The shift in seasons from winter to spring to summer to fall reveal the regular ebb of time, just as the seasons likewise point toward a final day when the winter of our discontent should fade into Spring’s first blossoms.
Alister McGrath is a professor of theology at Oxford University, but before this he received a PhD. in microbiology. He describes his own experience looking at the stars, and how his faith in God change the way he viewed his place in the universe:
“The more I learned about astronomy, the more I began to appreciate the vastness of the universe and the immensity of the distances between the stars. I found reflecting on these distances to be a melancholy affair…The span of human life seemed insignificantly brief, in comparison with the vast distances and timescales of the cosmos…[The stars] offered intimations of mortality without bringing me hope….
Yet when I began to think of the world as created, my outlook changed entirely….No longer were the stars silent memorials of transience, they were brilliant heralds of the love of God. I was not alone in the universe but walked and lived in the presence of a God who knew me and would never forget me.”
Even the rain that pelts our windowpanes whispers to us a story of a God who cares and a God who never forgets. I realize, of course, that science can never “prove” that God exists, but in His creation His fingerprints and His clues are everywhere to be found. But only to those willing to seek…
