But the Apostle speaks of 'a perfect man' in the singular and not of 'men' in the plural, as he has already described the result of the union of Jew and Gentile as being the making 'of twain one new man.' This remarkable expression sets forth, in the strongest terms, the vital unity which connects all members of the one body so closely that there is but one life in them all. There are many members, but one body. Their functions differ, but the life in them all is identical. The eye cannot say to the hand, 'I have no need of thee,' nor again the head to the feet, 'I have no need of you.' Each is necessary to the completeness of the whole, and all are necessary to make up the one body of Christ. It is His life which manifests itself in every member and which gives clearness of vision to the eye, strength and deftness to the hand. He needs us all for His work on the world and for His revelation to the world of the fulness of His life. In some parts of England there are bell-ringers who stand at a table on which are set bells, each tuned to one note, and they can perform most elaborate pieces of music by swiftly catching up and sounding each of these in the right place. All Christian souls are needed for the Master's hand to bring out the note of each in its place. In the lowest forms of life all vital functions are performed by one simple sac, and the higher the creature is in the scale the more are its organs differentiated. In the highest form of all, 'as the body is one, and hath many members, and all the members of the body, being many, are one body, so also is Christ.'
III. This perfect manhood is the possession of all who are in Christ.
The fulness of Christ is the fulness which belongs to Him, or that of which He is full. All which He is and has is to be poured into His servants, and when all this is communicated to them the goal will be reached. We shall be full-grown men, and more wonderful still, we all shall make one perfect man, and individual completenesses will blend into that which is more complete than any of these, the one body, which corresponds to the measure of the stature of the fulness of Christ.
This is the goal of humanity in which, and in which alone, the dreams of thinkers about perfectibility will become facts, and the longings that are deeply rooted in every soul will find their fulfilment. By our personal union with Jesus Christ through faith, our individual perfection, both in the sense of maturity and in that of the realisation of ideal manhood, is assured, and in Him the race, as well as the individual, is redeemed, and will one day be glorified. The Utopias of many thinkers are but partial and distorted copies of the kingdom of Christ. The reality which He brings and imparts is greater than all these, and when the New Jerusalem comes down out of heaven, and is planted on the common earth, it will outvie in lustre and outlast in permanence all forms of human association. The city of wisdom which was Athens, the city of power which was Rome, the city of commerce which is London, the city of pleasure which is Paris, 'pale their ineffectual fires' before the city in the light whereof the nations should walk.
The beginning of the process, of which the end is this inconceivable participation in the glory of Jesus, is simple trust in Him. 'He that is joined to the Lord is one spirit,' and he who trusts in Him, loves Him, and obeys Him, is joined to Him, and thereby is started on a course which never halts nor stays so long as the faith which started him abides, till he 'grows up into Him in all things which is the head, even Christ.' The experience of the Christian life as God means it to be, and by the communication of His grace makes it possible for it to become, is like that of men embarked on some sun-lit ocean, sailing past shining headlands, and ever onwards, over the boundless blue, beneath a calm sky and happy stars. The blissful voyagers are in full possession at every moment of all which they need and of all of His fulness which they can contain, but the full possession at every moment increases as they, by it, become capable of fuller possession. Increasing capacity brings with it increasing participation in the boundless fulness of Him who filleth all in all.
