"In our constant struggle to believe we are likely to overlook the simple fact that a bit of healthy disbelief is sometimes as needful as faith to the welfare of our souls. I would go further and say that we would do well to cultivate a reverent skepticism. It will keep us out of a thousand bogs and quagmires where others who lack it sometimes find themselves. It is no sin to doubt some things, but it may be fatal to believe everything. Faith is at the root of all true worship, and without faith it is impossible to please God. Through unbelief Israel failed to inherit the promises. “By grace are ye saved through faith.” “The just shall live by faith.” Such verses as these come trooping to our memories, and we wince just a little at the suggestion that unbelief may also be a good and useful thing. … Faith never means gullibility. The man who believes everything is as far from God as the man who refuses to believe anything. Faith engages the person and promises of God and rests upon them with perfect assurance. Whatever has behind it the character and word of the living God is accepted by faith as the last and final truth from which there must never be any appeal. Faith never asks questions when it has been established that God has spoken. 'Yea, let God be true, but every man a liar' (Rom. 3:4). Thus faith honors God by counting Him righteous and accepts His testimony against the very evidence of its own senses. That is faith, and of such we can never have too much. Credulity, on the other hand, never honors God, for it shows as great a readiness to believe anybody as to believe God Himself. The credulous person will accept anything as long as it is unusual, and the more unusual it is the more ardently he will believe. Any testimony will be swallowed with a straight face if it only has about it some element of the eerie, the preternatural, the unearthly."
