The determination of Christ to clear away all misunderstanding and all doubtfulness about the relation His professed followers hold to Him is strikingly exhibited in His subjecting Peter to a second and third interrogation. He invites Peter to search deeply into his spirit and to ascertain the very truth. It is the most momentous of all questions; and our Lord positively refuses to take a superficial, careless, matter-of-course answer. He will thus question, and thrice question, and probe to the quick all His followers. He seeks to scatter all doubt about our relation to Him, and to make our living connection with Him clear to our own consciousness, and to place our whole life on this solid basis of a clear, mutual understanding between Him and us. Our happiness depends upon our meeting His question with care and sincerity. Only the highest degree of human friendship will permit this persistent questioning, this beating of us back and back on our own feelings, deeper and deeper into the very heart of our affections, as if still it were doubtful whether we had not given an answer out of mere politeness or profession or sentiment. The highest degree of human friendship demands certainty, a basis on which it can build, a love it can entirely trust. Christ had made good His right thus to question His followers and to require a love that was sure of itself, because on His part He was conscious of such a love and had given proof that His affection was no mere sentimental, unfruitful compassion, but a commanding, consuming, irrepressible, unconquerable love--a love that left Him no choice, but compelled Him to devote Himself to men and do them all the good in His power.
Peter's self-knowledge is aided by the form the question now takes. He is no longer asked to compare the hold Christ has upon him with his interest in other things; but he is asked simply and absolutely whether love is the right name for that which connects him with his Lord. "_Lovest thou Me?_" Separating yourself and Me from all others, looking straight and simply at Me only, is "love" the right name for that which connects us? Is it love, and not mere impulse? Is it love, and not sentiment or fancy? Is it love, and not sense of duty or of what is becoming? Is it love, and not mere mistake? For no mistake is more disastrous than that which takes something else for love.
Now, to apprehend the significance of this question is to apprehend what Christianity is. Our Lord was on the point of leaving the world; and He left its future, the future of the sheep He loved so well and had spent His all upon, in the keeping of Peter and the rest, and the one security He demanded of them was the confession of love for Himself. He did not draw up a creed or a series of articles binding them to this and that duty, to special methods of governing the Church or to special truths they were to teach it; He did not summon them into the house of Peter or of Zebedee, and bid them affix their signatures or marks to such a document. He rested the whole future of the work He had begun at such cost on their love for Him. This security alone He took from them. This was the sufficient guarantee of their fidelity and of their wisdom. It is not great mental ability that is wanted for the furtherance of Christ's aims in the world. It is love of what is best, devotion to goodness. No question is made about their knowledge; they are not asked what views they have about the death of Christ; they are not required to analyse their feelings and say whence their love has sprung--whether from a due sense of their indebtedness to Him for delivering them from sin and its consequence, or from the grace and beauty of His character, or from His tender and patient consideration of them. There is no omission of anything vital owing to His being hurried in these morning hours. Three times over the question comes, and the third is as the first, a question solely and exclusively as to their love. Three times over the question comes, and three times over, when love is unhesitatingly confessed, comes the Apostolic commission, "Feed My sheep." Love is enough--enough not only to save the Apostles themselves, but enough to save the world.
