The remainder of this prayer reaches out to all generations of believers to the end. We may incidentally note that it shows that Jesus did not anticipate a speedy end of the history of the world or the Church; and also that it breathes but one desire, that for the Church's unity, as though He saw what would be its greatest peril. Characteristic, too, of the idealism of this Gospel is it that there is no name for that future community. It is not called 'church,' or 'congregation,' or the like--it is 'them also that believe on Me through their word,' a great spiritual community, held together by common faith in Him whom the Apostles preached. Is not that still the best definition of Christians, and does not such a conception of it correspond better to its true nature than the formal abstraction, 'the Church'? We can but touch in the most inadequate fashion the profound words of this section of the prayer which would take volumes to expound fitly. We note that it contains four periods, in each of which something is asked or stated, and then a purpose to be attained by the petition or statement is set forth. First comes the prayer for unity and what the answer to it will effect (v. 21). Now in this verse the unity of believers is principally regarded as resulting from the inclusion, if we may so say, of them all in the ineffable union of the Father and the Son. Jesus prays that 'they may all be one,' and also 'that they also may be in us' (Rev. Ver.). And their unity is no mere matter of formal external organisation nor of unanimity of creed, or the like, but it is a deep, vital unity. The pattern of it is the unity of the Father and the Son, and the power that brings it about is the abiding of all believers 'in us.' The result of such a manifestation in the world of a multitude of men, in all of whom one life evidently moves, fusing their individualities while retaining their personalities, will be the world's conviction of the divine mission of Jesus. The world was beginning to feel its convictions moving slowly in that direction, when it exclaimed: 'Behold how these Christians love one another!' The alienation of Christians has given barbs and feathers to its arrows of scorn. But it is 'the unity of the Spirit,' not that of a, great corporation, that Christ's prayer desires.
