Our Lord's words that we are making our subject indicate the paramount importance that He laid upon the acceptance of God's will as the ultimate rule of life. "Whosoever shall do the will of My Father which is in heaven, the same is my mother, and my sister, and my brother." "Ye are my friends, if ye do whatsoever I command you." That is the common ground on which we are all invited to stand, the ground of a common loyalty to God, of intense zeal for the cause of God. Our Lord gave His whole life to that cause. As His disciples watched Him on an occasion, they remembered that it was written: "The zeal of thine house hath eaten me up." Zeal is not a very popular quality because it is always disturbing the equanimity and self-complacency of lukewarm people. And then, we dislike to be thought fanatics. But I fancy that there will always be a touch of the fanatic about any very zealous Christian, and it is not worth while to suppress our zeal for fear of the world's judgment upon it. What we have to avoid is the misdirection of zeal. There is, no doubt, a zeal which is "not according to knowledge." We need to be sure, in other words, that our zeal is a zeal for God, and not a zeal for party or person or cause. It is no doubt quite easy to imagine that we are seeking to do God's will when we are merely seeking to impose on our own will. Self-seeking is quite destructive of the friendship and service of God. The Kingdom whose interests we are attempting to forward may turn out to be a Kingdom in which we expect to sit on the right hand or the left of the throne because of the brilliance of the service rendered.
