" When you take all three categories of temptation to self-reliance – wisdom, might and riches – they form a powerful inducement toward the ultimate form of pride, namely, atheism. The safest way to stay supreme in our own estimation is to deny anything above us. This is why the proud preoccupy themselves with looking down on others. A proud man is always looking down on things and people and, of course, as long as you are looking down, you cannot see something that is above you. But to preserve pride it may be simpler to proclaim that there is nothing above to look at (Psalm 10:4). Ultimately, the proud must persuade themselves that there is no God. "
