First of all, then, let me say a few words as to the general application of the metaphor.
The usual notion of these words confines itself to the natural meaning, and runs out into very true, but perhaps a little sentimental, considerations, laying hold of what is so plain on the very surface that I need not spend any time in speaking about it. Christ's pattern is my law; Christ's providence is my guidance and defence --which in the present case means Christ's companion-ship--is my safety, my sustenance--which in the present case means that Christ Himself is the bread of my soul. The Good Shepherd exercises care, which absolves the sheep from care, and in the present case means that my only duty is meek following and quiet trust. I am the Good Shepherd'--here is guidance, guardianship, companionship, sustenance--all responsibility laid upon His broad shoulders, and all tenderness in His deep heart, and so for us simple obedience and quiet trust.
Another way by which we get the whole significance of this symbol is by noticing how the idea is strengthened by the word that accompanies it. Christ does not say I am a Shepherd,' but He says, I am the good Shepherd.' At first sight that word good' is interpreted, as I have said, in a kind of sentimental, poetic way, as expressing our Lord's tenderness and love and care; but I do not think that is the full meaning here. You find up and down this Gospel of St. John phrases such as, I am the true bread,' I am the true vine,' and the meaning of the word that is here translated good' is very nearly parallel with that idea. The true bread, the true vine, the true Shepherd--which comes to this, to use modern phraseology, that Jesus Christ, in His relation to you and me, fulfils all that in figure and shadow is represented to the meditative eye by that lower relationship between the material shepherd and his sheep. That is the picture, this the reality. There is another point to be made clear, and that is, that whilst the word good' is perhaps a fair enough representation of that which is employed by our Lord, there is a special force and significance attached to the original, which is lost in our Bible. I do not know that it could have been preserved; but still it is necessary to state it. The expression here is the one that is generally rendered fair,' or lovely,' or beautiful,' and it belongs to the genius of that wonderful tongue in which the New Testament is written that it has a name for moral purity, considered as being lovely, the highest goodness, and the serenest beauty, which was what the old Greeks taught, howsoever little they may have practised it in their lives. And so here the thought is that the Shepherd stands before us, the realisation of all which that name means, set forth in such a fashion as to be infinitely lovely and perfectly fair, and to draw the admiration of any man who can appreciate that which is beautiful, and can admire that which is of good report.
There is another point still in reference to this first view of the text. Our Lord not only declares that He is the reality of which the earthly shepherd is the shadow, and that He as such is the flawless, perfect One, but that He alone is the reality. I am the Good Shepherd; in Me and in Me alone is that which men need.' And that leads me to another point which must just be mentioned, that we shall not reach the full meaning of these great words without taking into account the history of the metaphor in the Old Testament. Christ gives a second edition of the figure, and we are to remember all that went before. The Lord is my Shepherd, I shall not want'; Thou leddest Thy people like a flock, by the hand of Moses and Aaron.' These are but specimens of a continuous series of utterances in the old Revelation in which Jehovah Himself is the Shepherd of mankind; and there is also another class of passages of which I will quote one or two. He shall feed His flock like a shepherd, and carry them in His arms.' Awake, O sword, against the Man who is my fellow; smite the Shepherd, and the sheep shall be scattered.' There were, we should remember, two streams of representation, according to the one of which God Himself was the Shepherd of Israel, and according to the other of which the Messiah was the Shepherd; and here, as I believe, Jesus lays His hand on both the one and the other, and says: They are Mine, and they testify of Me.' So sweet, so gracious are the words, that we lose the sense of the grandeur of them, and need to think before we are able to understand how great and immense the claim that is made here upon our faith, and that this Man stands before us and arrogates to Himself the divine prerogative witnessed from of old by psalmist and prophet, and says that for Him were meant the prophecies of ancient times that spake of a human shepherd, and asserts that all the sustenance, care, authority, command, which the emblem suggests meet in Him in perfect measure.
