Others expect virtue to be as easy as it is beautiful. Religion should conduce to one's comfort. They like incense, but not the smell of brimstone. They would remain forever content on Tabor, but the dark frown of Calvary is insupportable. Beautiful churches, artistic music, eloquent preaching on interesting topics, that is their idea of religion; that is what they intend religion--their religion--shall be, and they proceed to cut out whatever jars their finer feelings. This is fashionable, but it is not Christian: to do anything for God--if it is easy; and if it is hard,--well, God does not expect so much of us. You will see at a glance that this sort of a thing is fatal to the sense of God in the soul; it has for its first, direct and immediate effect to weaken little by little the faith until it finally kills it altogether. Sloth is a microbe. It creeps into the soul, sucks in its substance and causes a spiritual consumption. This is neither an acute nor a violent malady, but it consumes the patient, dries him up, wears him out, till life goes out like a lamp without oil. CHAPTER XVII. WHAT WE BELIEVE. OUR first duty to God, and the first obligation imposed upon us by the First Commandment is Faith, or belief in God--we must know Him. Belief is solely a manner of knowing. It is one way of apprehending, or getting possession of, a truth. There are other ways of acquiring knowledge; by the senses, for instance, seeing, hearing, etc., and by our intelligence or reason. When truth comes to us through the senses, it is called experience; if the reason presents it, it is called science; if we use the faculty of the soul known as faith, it is belief. You will observe that belief, experience and science have one and the same object, namely, truth. These differ only in the manner of apprehending truth. Belief relies on the testimony of others; experience, on the testimony of the senses; science, on that of the reason. What I believe, I get from others; what I experience or understand, I owe to my individual self. I neither believe nor understand that Hartford exists--I see it. I neither understand nor see that Rome exists--I believe it. I neither see nor believe that two parallel lines will never meet--I reason it out, I understand it. Now it is beside the question here to object that belief, or what we believe, may or may not be true. Neither is all that we see, nor all that our reason produces, true. Human experience and human reason, like all things human, may err. Here we simply remark that truth is the object of our belief, as it is the object of our experience and of understanding. We shall later see that if human belief may err, faith or divine belief cannot mislead us, cannot be false.
