Here is one. Suppose a man who, like the most of us, believes that there is a God, believes that he has something to do with Him, believes that he is going to die, believes that the future state is, in some way or other, and in some degree, one of retribution; and from Monday morning to Saturday night he ignores all these facts, and never allows them to influence one of his actions. May I venture to speak direct to this hypothetical person, whose originals are dotted about in my audience? It would be the very same to you if you said 'No' instead of 'Yes' to all these affirmations. The fact that there is a God does not make a bit of difference to what you do, or what you think, or what you feel. The fact that there is a future life makes just as little difference. You are going on a voyage next week, and you never dream of getting your outfit. You believe all these things, you are an intelligent man--you are very likely, in a great many ways, a very amiable and pleasant one; you do many things very well; you cultivate congenial virtues, and you abhor uncongenial vices; but you never think about God; and you have made absolutely no preparation whatever for stepping into the scene in which you know that you are to live. Well, you may be a very wise man, a student with high aims, cultivated understanding, and all the rest of it. I want to know whether, taking into account all that you are, and your inevitable connection with God, and your certain death and certain life in a state of retribution--I want to know whether we should call your conduct sanity or insanity? Which? Take another picture. Here is a man that believes--really believes--the articles of the Christian creed, and in some measure has received them into his heart and life. He believes that Jesus Christ, the Son of God, died for him upon the Cross, and yet his heart has but the feeblest tick of pulsating love in answer. He believes that prayer will help a man in all circumstances, and yet he hardly ever prays. He believes that self-denial is the law of the Christian life, and yet he lives for himself. He believes that he is here as a 'pilgrim' and as a 'sojourner,' and yet his heart clings to the world, and his hand would fain cling to it, like that of a drowning man swept over Niagara, and catching at anything on the banks. He believes that he is sent into the world to be a 'light' of the world, and yet from out of his self-absorbed life there has hardly ever come one sparkle of light into any dark heart. And that is a picture, not exaggerated, of the enormous majority of professing Christians in so-called Christian lands. And I want to know whether we shall call that sanity or insanity?
