This was the sorrowing cry of Christ, "O righteous Father, the world hath not known thee!" This was His joy, "I have known thee, and these have known that thou hast sent me!"

But if Christ desired that His Father's name should be glorified, how was this to be accomplished? By what medium, or means? Now I would here observe that God's method of revealing Himself to man has ever been to do so by living men; and the Bible is a true record of such revelations in the past. Christianity is not the philosophy of life, but life itself; and is a revelation, not of abstract truth, but of the living personal God to living persons as His children, whom He hath created to glorify and enjoy Him for ever. The first grand medium of this revelation is the eternal Son of God. The very essence of God's character being love, He did not exist from all eternity with a mere capacity of loving, but without an object to love; like an eye capable of seeing light, but with no light to see. The object of His love was His Son, who from all eternity responded to that love and rejoiced in His Father. This eternal Son, when manifested in the flesh, revealed His Father directly, so that He could say, in all He was, and in all He did, and, in a true sense, in all He suffered, "He that hath seen me, hath seen the Father;" and men could say of Him, "We beheld His glory, the glory as of the only-begotten of the Father, full of grace and truth;" "The glory of God" was "in the face of Jesus Christ." Again, He had also, as the Son of Man, glorified His Father; and, by His reverence for, confidence in, and obedience to, Him, and by His joy in Him, had indirectly revealed what he knew God to be to Him and to all as a Father. "I have glorified Thee on the earth: I have finished the work which Thou gavest me to do." Such was His finished work. But something more was yet to be accomplished. Ere He descends to Gethsemane, He desires anew to have the joy of revealing a Father's heart by revealing to the world His own heart of love as a Son to that Father. Hence His prayer, "Glorify thy Son, that thy Son also may glorify thee." He does not prescribe the new circumstances in which His long-tried and perfect filial confidence and love as a Son were to be manifested. With the absolute consecration of true sonship He leaves these circumstances to be determined by His Father. Now, as on the cross, He commits His spirit, as a little child, into His Father's hands. He desires only that in any way, by any means, He may have the joy of showing forth the reality, the endurance, and the triumph of His Sonship. His Father may fill His cup according to His own will, the Son will drink it. The Father may permit a crown of thorns to be placed on His brow, and every conceivable horror of great darkness from the hate of men and devils to be cast over Him like a funeral-pall; He may be rejected by all His brethren and by the Church and by the State—"Amen!" He cries. Let His body be broken and His blood shed, He will give thanks! One thing only He prays for, "Glorify thy Son, that thy Son also may glorify thee!" As a further end to be accomplished, He prays that He may have the joy of making others share the same divine love and joy, and therefore adds, "As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him. And this is life eternal, that they might know thee, the only true God, and Jesus Christ, whom thou hast sent."

But while He as the Son was to be the first revealer of God the Father, He was not, therefore, to be the only revealer. He was the firstborn of many brethren in whom the same love was to be reproduced, and by whom the same high duty was to be performed. If the light of the glory of God shone directly in the face of Jesus Christ, that light was to be transmitted to those who were to shine as lights in the world, that others seeing them might glorify the same God. For now, as ever, God in a real sense manifests Himself in the flesh. Hence our Lord's desire that His brethren should, as sons, reveal the Father, like Himself the Son. He says accordingly, "As thou hast sent me into the world, even so have I also sent them into the world." Sent whom? Not apostles only, but those also who should believe through their word; not ministers of the Church only, but members also; all, in short, who were qualified to convince the world that God was a Father, by convincing it of this truth, that God had sent His Son to save sinners—the "faithful saying, worthy of all acceptation."

But the question is further suggested, What is this qualification? What is this which men must possess in order to accomplish Christ's purpose of inducing the world to believe? What is this evidence of Christianity which they are to present to the eyes of unbelieving men, by seeing which these are to know and glorify God as their Father in Christ? We reply, it is the oneness of those who are to be ambassadors from God and fellow-workers with Christ. "I pray for them," He says, and not for them only, but "for them also who shall believe on me through their word; that they all may be one; as thou, Father, art in me, and I in thee, that they may be one in us; that the world may believe that thou hast sent me."

Now this leads me to consider more particularly the nature of this oneness which is essential for such a successful mission as will convince the world of the truth of Christ's mission from the Father. What is meant by this oneness, or this union?

We are guided in our inquiry by three features which characterize it. First, It is a oneness such as subsists between Christ and God; secondly, It is a oneness which can be seen or appreciated; thirdly, It is a oneness which is calculated from its nature to convince the world of the truth of Christ's mission.

Now there are many kinds of union among men, which, however wonderful or excellent, may be set aside as obviously not fulfilling these conditions, and not such, therefore, as Christ prayed for. There is, e. g., the unity of an army which marches as one man, implicitly obeying its commander even unto death and without a question. Yet, however grand this is, and however illustrative of the character of good soldiers of Jesus Christ, it does not fulfil the conditions specified. Nor does the wonderful unity of a State, which makes and imposes laws, proclaims war or peace, administers justice, and executes its judgments. In neither case is there any union such as subsists betwixt God and Christ; nor such as is in any sense adapted to convince the world that God has sent His Son to save sinners. The same may be alleged of any outward and visible unity of a body of men which might be called a Church. Its organization might be as wonderful, and its members as disciplined, and its power as remarkable, as those of an army; it might be held together like a state by its laws and its enactments, its rewards and punishments, and might energetically advance until it possest the dominion of the world, and attracted such attention as that all men might marvel at it; its members might assent to all the details of a creed however large; the same rights and ceremonies and modes of worship might be repeated throughout all its parts; and it might be able to continue its organized existence from age to age,—yet it would by no means follow that any such system, however remarkable, possest that inward spiritual unity desired in Christ's prayer, no more than the compact unity of Brahminism does, nor the still more extraordinary unity of Buddhism, with its temples, its priesthood, its creed, its rites and ceremonies, continuing unchanged during teeming centuries, and dominating over hundreds of millions of the human race. May not all these and many similar unities be fully and satisfactorily accounted for by principles in human nature, altogether irrespective of the fact of a supernatural power having come into the world to which their origin or continuance is owing? For there is a oneness in the churchyard as well as in the church. There might be a oneness of assent amongst a deaf multitude with regard to the beauty of music, because determined by the fiat of authority, but not as the result of hearing and of taste; and the same kind of oneness of judgment as to the beauty of pictures, on the part of those who were blind. Unity alone proves nothing, apart from its nature and its origin.

There is but one kind of unity or oneness which fulfils the specified conditions, and that is, oneness of character or of spiritual life—in one word, the oneness of love;—for this is the highest condition of a personal spirit. It is such love as God had and has to Christ; "That the love wherewith thou has loved me may be in them;" such love as the Son has to the Father, and such as He manifested to His disciples that very evening when, conscious of His divine glory, and "knowing that he was come from God, and went to God," He girded Himself with a towel and washed His disciples' feet. Hence the declaration, "The glory," that is, of character, "which thou gavest me I have given them, that they," through its possession, "may be one, even as we are one: I in them, and thou in me." Hence again His saying, "They are not of the world, even as I am not of the world;" and His prayer, "I pray not that thou shouldst take them out of the world, but that thou shouldst keep them from the evil." Such love as this, when in the soul of ordinary men, does not originate in their own hearts, however naturally benevolent or affectionate these may be. Our Lord in this prayer recognizes it as inseparable from faith in His own teaching, and from personal conviction of the truth which they themselves were to preach; for they had received His words, and had "known surely that I came out from thee, and they have believed that thou didst send me"; and so He prays, "Sanctify them through thy truth; thy word is truth."

Now, if we would divide, as with a prism, this pure light of love, we might discern it as being composed, as it were, of at least two colors, or features—first, love to God, exprest in the desire that He should be known; secondly, love to man, exprest in self-sacrifice that all should share this true love. But these very features we discern as first existing in God the Father and in Christ the Son; for God desires, from the necessity of His own nature, that He should be known, and that all His rational creatures should see the glory of His character, and, in seeing it, should live. God has also manifested His love, according to the law of love, by giving and by self-sacrifice, inasmuch as He "spared not his own Son, but delivered him up for us all." In like manner, the Son desired that His Father might be known, and to accomplish this He became incarnate. He has manifested His love also in the form of self-sacrifice, in that His whole life and death were an offering up of Himself as a sacrifice unto God, and as an atonement for the sins of the world, in order that all men might be made partakers of His own eternal life in God. This, too, is the "mind" of the Holy Spirit, for He glorifies the Son, that the Son may glorify the Father, and glorifies Him in and by His true Church. Hence, wherever true love exists in man, it will manifest itself in these two forms; it will ever desire that God may be known, and will never "seek its own," but sacrifice itself that this end may be attained. In such oneness as this of mind, spirit, character—in one word, love—there is realized the first condition of that oneness for which our Lord prayed.

Secondly, This unity of character fulfils the second condition in its being such as the world can in some degree see and appreciate. Blind as the world is, it can see love in the form of self-sacrifice at least, seeking its good, even tho it may not at once see in this a revelation of such love as has its origin in the love of God to man. The world's heart can perceive more things and greater things than can its intellect. The child of the statesman or man of science may not be able to comprehend the world-politics of the one or the scientific discoveries of the other; but it can see and feel the love revealed in the glance of the eye, in the smile on the lips, or in the arms that clasp it to the bosom; and in seeing this, it sees an infinitely greater thing than the politics of the one or the scientific discoveries of the other. It sees, too, in this, tho unconsciously, the love of the Father's heart which fills the universe with glory, even as its eye, when opened to a little light, sees the same light which illumines a thousand worlds. And thus can the world see the light of love. Those who are in prison, in nakedness, or in thirst, are quite able to see and to appreciate the love that, for Christ's sake, visits them, clothes them, and gives them drink. The wretched lepers in the lazar-house, into which no one could enter and ever return to the world, could see and appreciate the love of the Moravian missionary who visited them, and who shut the door for ever between him and all he knew and loved, that he might share and alleviate the horrors of his wretched brethren whom he loved more than all. Blind as the world is, it can see this or nothing; bad as it is, it can appreciate this goodness or none.
