WHAT suggested this lovely parable of the vine and the branches is equally unimportant and undiscoverable. Many guesses have been made, and, no doubt, as was the case with almost all our Lord's parables, some external object gave occasion for it. It is a significant token of our Lord's calm collectedness, even at that supreme and heart-shaking moment, that He should have been at leisure to observe, and to use for His purposes of teaching, something that was present at the instant. The deep and solemn lessons which He draws, perhaps from some vine by the wayside, are the richest and sweetest clusters that the vine has ever grown. The great truth in this chapter, applied in manifold directions, and viewed in many aspects, is that of the living union between Christ and those who believe on Him, and the parable of the vine and the branches affords the foundation for all which follows. We take the first half of that parable now. It is somewhat difficult to trace the course of thought in it, but there seems to be, first of all, the similitude set forth, without explanation or interpretation, in its most general terms, and then various aspects in which its applications to Christian duty are taken up and reiterated, I simply follow the words which I have read for my text. I. We have then, first, the Vine in the vital unity of all its parts. 'I am the True Vine,' of which the material one to which He perhaps points, is but a shadow and an emblem. The reality lies in Him. We shall best understand the deep significance and beauty of this thought if we recur in imagination to some of those great vines which we sometimes see in royal conservatories, where for hundred of yards the pliant branches stretch along the espaliers, and yet one life pervades the whole, from the root, through the crooked stem, right away to the last leaf at the top of the farthest branch, and reddens and mellows every cluster, 'So,' says Christ, 'between Me and the totality of them that hold by Me in faith there is one life, passing ever from root through branches, and ever bearing fruit.'
