Could God be more obvious than He is? Could He erase all atheism? Yes. … But He doesn’t. Why? Because God is only interested in His revelation being clear enough for the purposes He has in revealing Himself. That is to say, God’s revelation is about God’s rather than man’s goals. And it is not man, therefore, who determines how clear He must be. Man’s purposes are often at odds with those of God. As it turns out, God is actually not that interested in people simply believing that He exists. Consider the parallel of Jesus in the Gospels. How often does Christ actually conceal His teaching and His identity precisely because He knows that people will simply abuse His teaching or seek to manipulate His identity for their own ends? Christ is most clear to those who pursue, who hunger, who thirst—and he satisfies them, as in the case of the woman at the well (John 4). This does not mean that His identity was, as such, unclear. It means that He was not interested in maximal clarity. His clarity was fitting to His own purpose in coming and revealing Himself and His Father. … Why would He then ‘fix’ what isn’t, by His standards, broken?
