These questions are answered in vv. 19 and 20. It is made very plain that it is no question of numbers, but of union with one another and the Lord. Let it be remembered that the whole discourse has grown out of the strife with one another which should be the greatest. Our Lord has already shown that, instead of ambition to be the greatest, there must be readiness to be the least. He now makes it plain that instead of strife and division there must be agreement, unity in heart and desire. But if only there be this unity, this blending of hearts in prayer, there is found the true idea of the Church. Two disciples in full spiritual agreement, with hearts uplifted to the Father in heaven, and Christ present with them,--there is what may be called the primitive cell of the Church, the body of Christ complete in itself, but in its rudimentary or germinal form. It comes to this, that the presence of Christ with His people and of His spirit in them, uniting them with one another and with Him, is that which constitutes the true and living church; and it is only when thus met in the name of Christ, and acting in the spirit of Christ, that assemblies of believers, whether large or small, have any guarantee that their decrees on earth are registered in heaven, or that the promise shall be fulfilled to them, that what they ask "shall be done for them of My Father which is in heaven." These words were spoken in the day of small things, when the members of the Church were reckoned by units; therefore it is a mistake to use them as if very small gatherings for prayer were especially pleasing to the great Head of the Church. It does indeed remain true, for the encouragement of the faithful few, that wherever two or three are met in the name of Jesus He is there; but that makes it no less disappointing when the numbers might be reasonably expected to be very much larger. Because our Lord said, "Better two of you agreed than the whole twelve at strife," does it follow that two or three will have the power in their united prayers which two or three hundred would have? The stress is not on the figure, but on the agreement. The words "There _am I_ in the midst of them" are very striking as a manifestation of that strange consciousness of freedom from limitations of time and place, which the Lord Jesus felt and often expressed even in the days of His flesh. It is the same consciousness which appears in the answer to the cavil of the Jews as to the intimacy with Abraham He seemed to them to claim,--"Before Abraham was, I am." As a practical matter also it suggests that we do not need to ask and wait for the presence of the Master, when we are truly met in His name. It is not _He_ that needs to be entreated to draw near to us: "There _am I_."
