2. The example of their Saviour is another argument for brotherly love: As I have loved you. It is this that makes it a new commandment—that this rule and reason of love (as I have loved you) is perfectly new, and such as had been hidden from ages and generations. Understand this, (1.) Of all the instances of Christ's love to his disciples, which they had already experienced during the time he went in and out among them. He spoke kindly to them, concerned himself heartily for them, and for their welfare, instructed, counselled, and comforted them, prayed with them and for them, vindicated them when they were accused, took their part when they were run down, and publicly owned them to be dearer to him that his mother, or sister, or brother. He reproved them for what was amiss, and yet compassionately bore with their failings, excused them, made the best of them, and passed by many an oversight. Thus he had loved them, and just now washed their feet; and thus they must love one another, and love to the end. Or, (2.) It may be understood of the special instance of love to all his disciples which he was now about to give, in laying down his life for them. Greater love hath no man than this, ch. xv. 13. Has he thus loved us all? Justly may he expect that we should be loving to one another. Not that we are capable of doing any thing of the same nature for each other (Ps. xlix. 7), but we must love one another in some respects after the same manner; we must set this before us as our copy, and take directions from it. Our love to one another must be free and ready, laborious and expensive, constant and persevering; it must be love to the souls one of another. We must also love one another from this motive, and upon this consideration—because Christ has loved us. See Rom. xv. 1, 3; Eph. v. 2, 25; Phil. ii. 1-5.
3. The reputation of their profession (v. 35): By this shall all men know that you are my disciples, if you have love one to another. Observe, We must have love, not only show love, but have it in the root and habit of it, and have it when there is not any present occasion to show it; have it ready. "Hereby it will appear that you are indeed my followers by following me in this." Note, Brotherly love is the badge of Christ's disciples. By this he knows them, by this they may know themselves (1 John ii. 14), and by this others may know them. This is the livery of his family, the distinguishing character of his disciples; this he would have them noted for, as that wherein they excelled all others—their loving one another. This was what their Master was famous for; all that ever heard of him have heard of his love, his great love; and therefore, if you see any people more affectionate one to another than what is common, say, "Certainly these are the followers of Christ, they have been with Jesus." Now by this it appears, (1.) That the heart of Christ was very much upon it, that his disciples should love one another. In this they must be singular; whereas the way of the world is to be every one for himself, they should be hearty for one another. He does not say, By this shall men know that you are my disciples—if you work miracles, for a worker of miracles is but a cypher without charity (1 Cor. xiii. 1, 2); but if you love one another from a principle of self-denial and gratitude to Christ. This Christ would have to be the proprium of his religion, the principal note of the true church. (2.) That it is the true honour of Christ's disciples to excel in brotherly love. Nothing will be more effectual than this to recommend them to the esteem and respect of others. See what a powerful attractive it was, Acts ii. 46, 47. Tertullian speaks of it as the glory of the primitive church that the Christians were known by their affection to one another. Their adversaries took notice of it, and said, See how these Christians love one another, Apol. cap. 39. (3.) That, if the followers of Christ do not love one another, they not only cast an unjust reproach upon their profession, but give just cause to suspect their own sincerity. O Jesus! are these thy Christians, these passionate, malicious, spiteful, ill-natured people? Is this thy son's coat? When our brethren stand in need of help from us, and we have an opportunity of being service able to them, when they differ in opinion and practice from us, or are any ways rivals with or provoking to us, and so we have an occasion to condescend and forgive, in such cases as this it will be known whether we have this badge of Christ's disciples.
Peter's Self-Confidence.
36 Simon Peter said unto him, Lord, whither goest thou? Jesus answered him, Whither I go, thou canst not follow me now; but thou shalt follow me afterwards. 37 Peter said unto him, Lord, why cannot I follow thee now? I will lay down my life for thy sake. 38 Jesus answered him, Wilt thou lay down thy life for my sake? Verily, verily, I say unto thee, The cock shall not crow, till thou hast denied me thrice.
In these verses we have,
I. Peter's curiosity, and the check given to that.
1. Peter's question was bold and blunt (v. 36): Lord, whither goest thou? referring to what Christ had said (v. 33), Whither I go, you cannot come. The practical instructions Christ had given them concerning brotherly love he overlooks, and asks no questions upon them, but fastens upon that concerning which Christ purposely kept them in the dark. Note, It is a common fault among us to be more inquisitive concerning things secret, which belong to God only, than concerning things revealed, which belong to us and our children, more desirous to have our curiosity gratified than our consciences directed, to know what is done in heaven than what we may do to get thither. It is easy to observe it in the converse of Christians, how soon a discourse of that which is plain and edifying is dropped, and no more said to it, the subject is exhausted; which in a matter of doubtful disputation runs into an endless strife of words.
2. Christ's answer was instructive. He did not gratify him with any particular account of the world he was going to, nor ever foretold his glories and joys so distinctly as he did his sufferings, but said what he had said before (v. 36): Let this suffice, thou canst not follow me now, but shalt follow me hereafter, (1.) We may understand it of his following him to the cross: "Thou hast not yet strength enough of faith and resolution to drink of my cup;" and it appeared so by his cowardice when Christ was suffering. For this reason, when Christ was seized, he provided for the safety of his disciples. Let these go their way, because they could not follow him now. Christ considers the frame of his disciples, and will not cut out for them that work and hardship which they are not as yet fit for; the day shall be as the strength is. Peter, though designed for martyrdom, cannot follow Christ now, not being come to his full growth, but he shall follow him hereafter; he shall be crucified at last, like his Master. Let him not think that because he escapes suffering now he shall never suffer. From our missing the cross once, we must not infer that we shall never meet it; we may be reserved for greater trials than we have yet known. (2.) We may understand it of his following him to the crown. Christ was now going to his glory, and Peter was very desirous to go with him: "No," saith Christ, "thou canst not follow me now, thou art not yet ripe for heaven, nor hast thou finished thy work on earth. The forerunner must first enter to prepare a place for thee, but thou shalt follow me afterwards, after thou hast fought the good fight, and at the time appointed." Note, Believers must not expect to be glorified as soon as they are effectually called, for there is a wilderness between the Red Sea and Canaan.
II. Peter's confidence, and the check given to that.
1. Peter makes a daring protestation of his constancy. He is not content to be left behind, but asks, "Lord why cannot I follow thee now? Dost thou question my sincerity and resolution? I promise thee, if there be occasion, I will lay down my life for thy sake." Some think Peter had a conceit, as the Jews had in a like case (ch. vii. 35), that Christ was designing a journey or voyage into some remote country, and that he declared his resolution to go along with him wherever he went; but, having heard his Master so often speak of his own sufferings, surely he could not understand him any otherwise than of his going away by death; and he resolves as Thomas did that he will go and die with him; and better die with him than live without him. See here, (1.) What an affectionate love Peter had to our Lord Jesus: "I will lay down my life for thy sake, and I can do no more." I believe Peter spoke as he thought, and though he was inconsiderate he was not insincere, in his resolution. Note, Christ should be dearer to us than our own lives, which therefore, when we are called to it, we should be willing to lay down for his sake, Acts xx. 24. (2.) How ill he took it to have it questioned, intimated in that expostulation, "Lord, why cannot I follow thee now? Dost thou suspect my fidelity to thee?" 1 Sam. xxix. 8. Note, It is with regret that true love hears its own sincerity arraigned, as ch. xxi. 17. Christ had indeed said that one of them was a devil, but he was discovered, and gone out, and therefore Peter thinks he may speak with the more assurance of his own sincerity; "Lord, I am resolved I will never leave thee, and therefore why cannot I follow thee?" We are apt to think that we can do any thing, and take it amiss to be told that this and the other we cannot do, whereas without Christ we can do nothing.
2. Christ gives him a surprising prediction of his inconstancy, v. 38. Jesus Christ knows us better than we know ourselves, and has many ways of discovering those to themselves whom he loves, and will hide pride from. (1.) He upbraids Peter with his confidence: Wilt thou lay down thy life for my sake? Me thinks, he seems to have said this with a smile: "Peter, thy promises are too large, too lavish to be relied on; thou dost not consider with what reluctancy and struggle a life is laid down, and what a hard task it is to die; not so soon done as said." Christ hereby puts Peter upon second thoughts, not that he might retract his resolution, or recede from it, but that he might insert into it that necessary proviso, "Lord, thy grace enabling me, I will lay down my life for thy sake." "Wilt thou undertake to die for me? What! thou that trembledst to walk upon the water to me? What! thou that, when sufferings were spoken of, criedst out, Be it far from thee, Lord? It was an easy thing to leave thy boats and nets to follow me, but not so easy to lay down thy life." His Master himself struggled when it came to his, and the disciple is not greater than his Lord. Note, It is good for us to shame ourselves out of our presumptuous confidence in ourselves. Shall a bruised reed set up for a pillar, or a sickly child undertake to be a champion? What a fool am I to talk so big. (2.) He plainly foretels his cowardice in the critical hour. To stop the mouth of his boasting, lest Peter should say it again, Yea Master, that I will, Christ solemnly asserts it with, Verily, verily, I say unto thee, the cock shall not crow till thou hast denied me thrice. He does not say as afterwards, This night, for it seems to have been two nights before the passover; but, "Shortly thou wilt have denied me thrice within the space of one night; nay, within so short a space as between the first and last crowing of the cock: The cock shall not crow, shall not have crowed his crowing out, till thou has again and again denied me, and that for fear of suffering." The crowing of the cock is mentioned, [1.] To intimate that the trial in which he would miscarry thus should be in the night, which was an improbable circumstance, but Christ's foretelling it was an instance of his infallible foresight. [2.] Because the crowing of the cock was to be the occasion of his repentance, which of itself would not have been if Christ had not put this into the prediction. Christ not only foresaw that Judas would betray him though he only in heart designed it, but he foresaw that Peter would deny him though he did not design it, but the contrary. He knows not only the wickedness of sinners, but the weakness of saints. Christ told Peter, First, That he would deny him, would renounce and abjure him: "Thou wilt not only not follow me still, but wilt be ashamed to own that ever thou didst follow me." Secondly, That he would do this not once only by a hasty slip of the tongue, but after he had paused would repeat it a second and third time; and it proved too true. We commonly give it as a reason why the prophecies of scripture are expressed darkly and figuratively, because, if they did plainly describe the event, the accomplishment would thereby either be defeated or necessitated by a fatality inconsistent with human liberty; and yet this plain and express prophecy of Peter's denying Christ did neither, nor did in the least make Christ accessary to Peter's sin. But we may well imagine what a mortification it was to Peter's confidence of his own courage to be told this, and to be told it in such a manner that he durst not contradict it, else he would have said as Hazael, What! is thy servant a dog? This could not but fill him with confusion. Note, The most secure are commonly the least safe; and those most shamefully betray their own weakness that most confidently presume upon their own strength, 1 Cor. x. 12.
