Then let me say, too, that if we love Him, it will be the motive power and spring of all manner of obediences and glad services. Love is the mother-tincture, so to speak, which you can colour, and to which you can add in various ways, and produce variously tinted and tasted and perfumed commixtures. Love lies at the foundation of all Christian goodness. It will lead to the subjugation of the will; and that is the thing that is most of all needed to make a man righteous and pure. So St. Augustine's paradox, rightly understood, is a magnificent truth, 'Love! and do what you will.' For then you will be sure to will what God wills, and you ought.
If this be the summing-up of all religion, a practical conclusion follows. When we feel ourselves defective in the glow and operative driving power of love to God, what is the right thing to do? When a man is cold, he will not warm himself by putting a clinical thermometer into his mouth, and taking his temperature, will he? Let him go into the sunshine and he will be warmed up. You can pound ice in a mortar, and except for the little heat generated by the impact of the pestle, it will keep ice still. But float the iceberg south into the tropics, and what has become of it? It has all run down into sweet, warm water, and mingled with the warm ocean that has dissolved it. So do not think about yourselves and your own loveless hearts so much, but think about God, and the infinite welling up of love in His heart to you, a great deal more. 'We love Him, because He first loved us'; therefore, to love Him more, we must feel more that He does love us.
III. Lastly, here is the ultimate word about our conduct to men.
I said that John, by leaving out any specification of the object of love, as well as by the verses that immediately follow, shows that he regards the emotion as one, though its direction is two-fold. That just comes to the plain truth, that the only victorious antagonist to the self-regarding temperament of average men, and the only power which will change philanthropy from a sentiment into a self-denying and active principle of conduct, is to be found in the belief of the love of God in Jesus Christ, and in answering love to Him.
That is a lesson for many sorts of people to-day. What they call altruism is no discovery of Christianity, but its practice is. I freely admit that there is much honest and self-sacrificing beneficence and benevolence which are not connected, in the men who practice them, with faith in Jesus Christ. But I question very much whether these would have existed if the story of the Cross had been unknown. And sure I am that the history of non-Christian attempts to promote the brotherhood of man, and to diffuse a wide and operative love of mankind, teaches us, on the one side, that the emotion is not strong enough to last, and to work, unless it is based on God's love in Jesus Christ. And the history of Christianity, on the other side, though with many defects and things to be ashamed of, teaches us, conversely, that wherever there is a genuine love of God, its exterior form, so to say, the outside of it which is presented to the world, will be true love to man.
Christian people, lay this to heart; you are to be mirrors of the love to which you turn for all blessedness and peace. It is of no use to say, 'My religion is the love of God' unless the love of God is manifested in the love of man. If you love God, you will love those that God loves, those for whom Christ died, those who are just like what _you_ were when you learned that God loved you. The service of God is the service of man.
