Properly speaking, faith is trust. This involves a wide latitude beyond our knowledge. If we trust a friend, we have faith in him, and we act upon that sentiment. But we are sometimes deceived, and this shows that our faith was in excess of our knowledge. Sometimes, indeed, it is quite independent of knowledge. We trust people because we like them, or because they like us. This infirmity is well known to sharpers and adventurers, who invariably cultivate a pleasing manner, and generally practise the arts of flattery. The same principle holds good in religion. It was sagaciously remarked by Hume that we ought to suspect every agreeable belief. The mass of mankind, however, are not so fastidious or discriminating. On the contrary, they frequently believe a thing because it _is_ pleasant, and for no other reason. How often have we heard Christian advocates prove the immortality of the soul to the complete satisfaction of their auditors by simply harping on man's desire to live for ever! Nay, there have been many great "philosophers" who have demonstrated the same doctrine by exactly the same means. Religious faith, to borrow a definition from _Chambers's Dictionary_, is usually "belief in the statement of another." There are a few mystics who profess to hold personal intercourse with God, but the majority, of mankind take their religion on trust. They believe it because they were taught it, and those who taught them believed it for the very same reason. When you trace back the revelation to its beginning, you always find that it is derived from men who lived a long time ago, or who perhaps never lived at all. Mohammed vouches for the Koran. Yes, but who will vouch for Mohammed? Thomas Paine well said that what is revelation to the man who receives it, is only hearsay to the man who gets it at secondhand. If anyone comes to you with a message from God, first button your pockets, and then ask him for his credentials. You will find that he has none. He can only tell you what someone else told him. If you meet the original messenger, he can only cry "thus saith the Lord," and bid you believe or be damned. To such a haughty prophet one might well reply, "My dear sir, what you say may be true, but it is very strange. Return to the being who sent you and ask him to give you better credentials. His word may be proof to you, but yours is no proof to me; and it seems reasonable to suppose that, if God had anything to tell to me, he could communicate personally to me as well as to you."
