The strangest of all theories as to the foundation of our belief in God is, that it has no foundation at all--that it is a belief which rests upon itself, an act of faith which is its own warrant. We are told that we can neither know that God is nor what God is, but that we can nevertheless believe in God, and ought to believe in Him, and can and ought to act as if we knew His existence and character. But surely belief without a reason must be arbitrary belief, and either to believe or act as if we knew what we do not know, can never be conduct to be justified, much less commended. Faith which is not rational is faith which ought to be rejected. We cannot believe what we do not know or think that we know. We have no right to believe more than we know. I know, for example, that the grass grows, and consequently I believe, and am justified in believing, that it grows. I do not know how the grass grows, and I do not believe how it grows; I can justify my believing about its growth nothing beyond what I know to be true. This law of belief is as binding for the highest as for the lowliest objects. If I have no reason for believing that there is a God, I have no right to believe that there is a God. If I do not know that God is infinite, I am bound not to believe that He is infinite. Belief is inseparable from knowledge, and ought to be precisely coextensive with knowledge. Those who deny this fundamental truth will always be found employing the words knowledge and belief in a capricious and misleading way.[13]
When man apprehends God as powerful, wise, and good--as possessed of will, reason, and righteousness--obviously he thinks of Him as bearing some likeness to himself, as having in an infinite or perfect measure qualities which human creatures have in a finite and imperfect measure. This can be no stumbling-block to any one who believes that God made man in His image, after His likeness. If man be in some respects like God, God must, of course, be in some respects like man. Power and freedom, knowledge and wisdom, love, goodness, and justice, are, according to this view, finitely in man, because they are infinitely in God. But it is a view which excites in certain minds deep aversion. There are men who protest, in the name of religion, in the name of God, against this anthropomorphic theism, as they call it. According to them, to attribute to God any human qualities, even the highest and best, is to limit and degrade Him--is contrary to reason and contrary to piety--is idolatrous and profane. The Psalmist represents the Lord as reproaching the wicked for supposing that He was like them in their wickedness--"altogether such an one as themselves;" but the modern philosophers to whom I am referring are horrified at the thought that the most righteous man, even in his righteousness, has any likeness to God. According to them, to think of God as wise is to dishonour Him, and to declare Him holy is to calumniate Him. To think of Him as foolish, and to pronounce Him wicked, are, in their eyes, only a little more irreverent and no more irrational.
