There are four things suggested to me by the words of our text--the Obligation, the Sufficiency, the Pattern, and the Motive, of Christian love. I. First, the Obligation of love. The two ideas of commandment and love do not go well together. You cannot pump up love to order, and if you try you generally produce, what we see in abundance in the world and in the Church, sentimental hypocrisy, hollow and unreal. But whilst that is true, and whilst it seems strange to say that we are commanded to love, still we can do a great deal, directly and indirectly, for the cultivation and strengthening of any emotion. We can either cast ourselves into the attitude which is favourable or unfavourable to it. We can either look at the facts which will create it or at those who will check it. We can go about with a sharp eye for the lovable or for the unlovable in man. We can either consciously war against or lazily acquiesce in our own predominant self-absorption and selfishness. And in these and in a number of other ways, our feelings towards other Christian people are very largely under our own control, and therefore are fitting subjects for commandment. Our Lord lays down the obligation which devolves upon all Christian people, of cherishing a kindly and loving regard to all others who find their place within the charmed circle of His Church. It is an obligation because He commands it. He puts Himself here in the position of the absolute Lawgiver, who has the right of entire and authoritative control over men's affections and hearts. And it is further obligatory because such an attitude is the only fitting expression of the mutual relation of Christian men, through their common relation to the Vine. If there be the one life-sap circling through all parts of the mighty whole, how anomalous and how contradictory it is that these parts should not be harmoniously concordant among themselves! However unlike any two Christian people are to each other in character, in culture, in circumstances, the bond that knits those who have the same relations to Jesus Christ one to another is far deeper, far more real, and ought to be far closer, than the bond that knits either of them to the men or women to whom they are likest in all these other respects, and to whom they are unlike in this central one. Christian men! you are closer to every other Christian man, down in the depths of your being, however he may be differenced from you by things that are very hard to get over, than you are to the people that you like best, and love most, if they do not participate with you in this common love to Jesus Christ.
