The way to counteract and conquer evil in the world is to give our own hearts to the dominion of good, and work the works of God while it is day. The strongest of all obstacles to the advance of evil is a clean and generous man, doing his duty from day to day, and winning others, by his cheerful fidelity, to serve the same Master. Diseases are not the only things that are contagious. Courage is contagious. Kindness is contagious. Manly integrity is contagious. All the positive virtues, with red blood in their veins, are contagious. The heaviest blow that you can strike at the kingdom of evil is just to follow the advice which the dying Sir Walter Scott gave to his son-in-law, Lockhart: "Be a good man." And if you want to know how, there is but one perfect and supreme example,—the life of Him who not only did no evil but went about doing good.

Now take that thought of fighting evil with good and apply it to our world and to ourselves.

Here are monstrous evils and vices in society. Let intemperance be the type of them all, because so many of the others are its children. Drunkenness ruins more homes and wrecks more lives than war. How shall we oppose it? I do not say that we shall not pass resolutions and make laws against it. But I do say that we can never really conquer the evil in this way. I hold with Phillips Brooks that "all prohibitory measures are negative. That they have their uses no one can doubt. That they have their limits is just as clear."

The stronghold of intemperance lies in the vacancy and despair of men's minds. The way to attack it is to make the sober life beautiful and happy and full of interest. Teach your boys how to work, how to read, how to play, you fathers, before you send them to college, if you want to guard them against the temptations of strong drink and the many shames and sorrows that go with it. Make the life of your community cheerful and pleasant and interesting, you reformers, provide men with recreation which will not harm them, if you want to take away the power of the gilded saloon and the grimy boozing-ken. Parks and play-grounds, libraries and music-rooms, clean homes and cheerful churches,—these are the efficient foes of intemperance. And the same thing is true of gambling and lubricity and all the other vices which drag men down by the lower side of their nature because the higher side has nothing to cling to, nothing to sustain it and hold it up.

What are you going to do, my brother-men, for this higher side of human life? What contribution are you going to make of your strength, your time, your influence, your money, your self, to make a cleaner, fuller, happier, larger, nobler life possible for some of your fellow-men? I do not ask how you are going to do it. You may do it in business, in the law, in medicine, in the ministry, in teaching, in literature. But this is the question: What are you going to give personally to make the human life of the place where you do your work, purer, stronger, brighter, better, and more worth living? That will be your best part in the warfare against vice and crime.

The positive method is the only efficient way to combat intellectual error and spiritual evil. False doctrines are never argued out of the world. They are pushed back by the incoming of the truth as the darkness is pushed back by the dawn. Phillips Brooks was right. It is not worth while to cross the street to break a man's idol. It is worth while to cross the ocean to tell him about God. The skilful fencer who attacks your doubts and drives you from corner to corner of unbelief and leaves you at last in doubt whether you doubt or not, does you a certain service. He gives you exercise, takes the conceit out of you. But the man who lays hold of the real faith that is hidden underneath your doubt,—the silent longing for God and goodness, the secret attraction that draws your heart toward Jesus Christ as the only one who has the words of everlasting life,—the man who takes hold of this buried faith and quickens it and makes you dare to try to live by it,—ah, that is the man who helps you indeed. My brothers, if any of you are going to be preachers remember this. What we men need is not so much an answer to our doubts, as more nourishment for our faith.

The positive method is the only way of victory in our struggle with the evil that dwells in our own nature and besets our own hearts. The reason why many men fail, is because they thrust the vice out and then forget to lay hold on the virtue. They evict the unclean spirit and leave a vacant house. To cease to do evil is important, but to learn to do good is far more important. Reformation never saved a man. Transformation is the only way. And to be transformed, a man must welcome the Spirit of Good, the Holy Spirit, into his heart, and work with Him every day, doing the will of God.

There are two ways of fighting fever. One is to dose the sick people with quinine and keep the fever down. The other is to drain the marshes, and purify the water, and cleanse the houses, and drive the fever out. Try negative, repressive religion, and you may live, but you will be an invalid. Try positive, vital religion, and you will be well.

There is an absorption of good that guards the soul against the infection of evil. There is a life of fellowship with Christ that can pass through the furnace of the world without the smell of fire on its garments,—a life that is full of interest as His was, being ever about His Father's business; a life that is free and generous and blessed, as His was, being spent in doing good, and refreshed by the sense of God's presence and approval.

Last summer, I saw two streams emptying into the sea. One was a sluggish, niggardly rivulet, in a wide, fat, muddy bed; and every day the tide came in and drowned out that poor little stream, and filled it with bitter brine. The other was a vigorous, joyful, brimming mountain-river, fed from unfailing springs among the hills; and all the time it swept the salt water back before it and kept itself pure and sweet; and when the tide came in, it only made the fresh water rise higher and gather new strength by the delay; and ever the living stream poured forth into the ocean its tribute of living water,—the symbol of that influence which keeps the ocean of life from turning into a Dead Sea of wickedness.
