And now, some one who feels a little freshened interest in this subject, some man who has never got hold of the gospel faith, says to himself: "I wonder if the preacher is going to explain to me what believing is, what faith is. I never heard any one succeed in explaining faith." Well, if you will pardon me, the best explanation of faith I ever heard was given by a negro preacher in Virginia. As the story was told me, one Sunday afternoon, a few years ago, some negroes were lying on the ground together, and one of them spoke and said, "Uncle Reuben, can you explain this: Faith in de Lord, and faith in de debbil?" "To be sure I can. There is two things: in de fust place, faith in de Lord, and then faith in de debbil. Now, in the fust place, fustly, there is faith. What is faith? Why, faith is jes faith. Faith ain't nothing less than faith. Faith ain't nothing more than faith. Faith is jest faith--now I done splain it." Really, that man was right, there is nothing to explain. Faith is as simple a conception as the human mind can have. How, then, can you explain faith? You are neither able to analyze it into parts, nor can you find anything simpler with which to compare it. So also as to some other things, that are perfectly easy and natural in practical exercise, and can not be explained. What is love? Well, I won't go into an elaborate metaphysical definition of love, but if I wanted a child to love me, I should try to exhibit myself in such a character to him and act in such ways that the little child would see in me something to love, and would feel like loving. There would then be no need of an explanation of what love is. Did you ever hear a satisfactory definition of laughter? If you wanted to make a man laugh, would you attempt to define laughter to him? You might possibly succeed in making a laughable definition; but otherwise definitions won't make a man laugh. You would simply say or do something ludicrous, and he would laugh readily enough if he was so disposed; and if the man be not in a mood for laughing, all your explanations are utterly useless. And so what is faith? There is nothing to explain. Everybody knows what faith is. If you want to induce a man to believe in the Lord Jesus Christ, you must hold up the Lord to him in His true character, and then, if he is in a mood to believe, he will believe, and if he is disinclined to belief, all your explanations will be fruitless. The practical result may even be obstructed by attempts to explain. What is faith? You know what faith is. Every one knows.
