'At that day ye shall know that I am in My Father, and ye in Me, and I in you. He that hath My commandments, and keepeth them, he it is that loveth Me; and he that loveth Me shall be loved of My Father, and I will love him, and will manifest Myself to him.'—JOHN xiv. 20, 21.
We have heard our Lord in the previous verse unveiling His deepest and strongest encouragements to His downcast followers. These were: His presence with them, their true sight of Him, and their participation in His life. The first part of our present text is closely connected with these, for it gives us their upshot and consequence. Because Christ's true disciple is conscious of Christ's presence, sees Him with the eyes of his spirit, and draws life from Him, therefore he will know by experience the deep truths of Christ's indwelling at once in the Father and in His servant, and of His servant's indwelling in Him. Our Lord had just previously been exhorting His disciples to _believe_ that He was in the Father and the Father in Him; and had been gently wondering at the slowness of their faith. Now He tells them that, when He is gone, their spiritual stature will be so increased as that they shall _know_ the thing which, with Him by their side, they found it so hard to believe.
The second part of our present text is the close of this whole section of our Lord's discourse, and in it He urges the requirement of practical obedience, as the sign and test of love, and as the condition of receiving these high and wonderful things of which He has been speaking. He has been unveiling spiritual blessings, which may seem recondite and up in the clouds, and which, as a matter of fact, have often been perverted into dreamy mysticisms of a most immoral and unpractical kind. And so He brings us sharp back again here to very plain truths, and would teach us that all these lofty and ineffable gifts of which He has been dimly speaking are to be reached only by the commonplace road of honest obedience and simple conformity to His commandments. In these last words of my text, He administers the antidote and the check to the possible abuses of the great things which He has been saying.
I. Note, then, first, the knowledge that comes with the Christ who comes.
'At that day' covers the whole period of which He has been speaking, between His withdrawal from the disciples and His final corporeal coming to judgment—that great day of which generations are but the moments. In it the men who love Him are to have His presence, His vision, His life, and because they have, 'Ye shall know that I am in My Father, and ye in Me, and I in you,' The principle that underlies these wonderful words is that Christian experience is the best teacher of fundamental Christian truth. Observe with what decision, and with what strange boldness, our Lord carries that principle into regions where we might suppose at first sight that it was altogether inapplicable. 'Ye shall know that I am in My Father.' How can such a thing as the relation between Christ and God ever be a matter of consciousness to us here upon earth? Must it not always be a truth that we must take on trust and believe because we have been told it, without having any verification in ourselves? Not so; remember what has gone before. If a man has the consciousness of Christ's presence with Him, sees Him with the true inward eye, which is the only real organ of real vision, and is drawing from Him, moment by moment, His own high and immortal life, then is it not true that this man's experiences are of such a sort as to be utterly inexplicable, except on the ground that they come from a divine source? If I have these experiences I know that it is Jesus Christ who gives them, and I know that He could not give them, if He did not dwell in God and were not divine. These new influences, this revolution in my being, this healing, constraining, cleansing touch, these calming, gladdening, elevating powers, these new hopes, these reversed desires, loving all to which I was formerly indifferent, and growing dead to all that formerly appealed most strongly to me; all these things bear upon their very front the signature that they are wrought by a divine hand, and as sure as I am of my own Christian consciousness, so sure am I that all its experiences proclaim their Author, and that Christ who gives me them is in God. 'Ye shall know that I am in My Father.'
