We have our duties to one another, yours to me, and mine to you: but we have all our duty to one else,--to Almighty God, who is beside us at this very moment--who followed us all this day, and knew all we did and didn't do, what we thought and didn't think,--who will watch over us all this night,--who is continually doing us good,--who is waiting to be gracious to us,--who is the great Physician, whose saving health will heal all our diseases, and redeem our life from destruction, and crown us with loving-kindness and tender mercies,--who can make death the opening into a better life, the very gate of heaven; that same death which is to all of us the most awful and most certain of all things, and at whose door sits its dreadful king, with that javelin, that sting of his, which is sin, our own sin. Death would be nothing without sin, no more than falling asleep in the dark to awake to the happy light of the morning. Now, I would have you think of your duty to this great God, our Father in heaven; and I would have you to remember that it is your duty to trust him, to believe in him. If you do not, your soul will be shipwrecked, you will go down in terror and in darkness. It is your duty to _obey_ him. Whom else in all this world should you obey, if not him? and who else so easily pleased, if we only do obey? It is your duty to speak the truth to him, not that he needs any man to tell him anything. He knows everything about everybody; nobody can keep a secret from him. But he hates lies; he abhors a falsehood. He is the God of truth, and must be dealt honestly with, in sincerity and godly fear; and, lastly, you must in a certain sense _reward_ him. You cannot give him money, for the silver and gold, the cattle upon a thousand hills, are all his already, but you can give him your grateful lives; you can give him your hearts; and as old Mr. Henry says, "Thanksgiving is good, but thanks-living is better." One word more; you should call your Doctor early. It saves time; it saves suffering; it saves trouble; it saves life. If you saw a fire beginning in your house, you would put it out as fast as you could. You might perhaps be able to blow out with your breath what in an hour the fire-engine could make nothing of. So it is with disease and the Doctor. A disease in the morning when beginning is like the fire beginning; a dose of medicine, some simple thing, may put it out, when if left alone, before night it may be raging hopelessly, like the fire if left alone, and leaving your body dead and in the ruins in a few hours. So, call in the Doctor soon; it saves him much trouble, and may save you your life. And let me end by asking you to call in the Great Physician; to call him instantly, to call him in time; there is not a moment to lose. He is waiting to be called; he is standing at the door. But he must be _called_,--he may be called too late. SERMON II. THE DOCTOR: HIS DUTIES TO YOU.
