"Greater love hath no man than this, that a man lay down his life for his friends. Ye are My friends, if ye do the things which I command you. No longer do I call you servants; for the servant knoweth not what his lord doeth: but I have called you friends; for all things that I heard from My Father I have made known unto you. Ye did not choose Me, but I chose you, and appointed you, that ye should go and bear fruit, and that your fruit should abide: that whatsoever ye shall ask of the Father in My name, He may give it you. These things I command you, that ye may love one another."--JOHN xv. 13-17.
These words of our Lord are the charter of our emancipation. They give us entrance into true freedom. They set us in the same attitude towards life and towards God as Christ Himself occupied. Without this proclamation of freedom and all it covers we are the mere drudges of this world,--doing its work, but without any great and far-reaching aim that makes it worth doing; accepting the tasks allotted to us because we must, not because we will; living on because we happen to be here, but without any part in that great future towards which all things are running on. But this is of the very essence of slavery. For our Lord here lays His finger on the sorest part of this deepest of human sores when He says, "The slave knows not what his master does." It is not that his back is torn with the lash, it is not that he is underfed and overworked, it is not that he is poor and despised; all this would be cheerfully undergone to serve a cherished purpose and accomplish ends a man had chosen for himself. But when all this must be endured to work out the purposes of another, purposes never hinted to him, and with which, were they hinted, he might have no sympathy, this is slavery, this is to be treated as a tool for accomplishing aims chosen by another, and to be robbed of all that constitutes manhood. Sailors and soldiers have sometimes mutinied when subjected to similar treatment, when no inkling has been given them of the port to which they are shipped or the nature of the expedition on which they are led. Men do not feel degraded by any amount of hardship, by going for months on short rations or lying in frost without tents; but they do feel degraded when they are used as weapons of offence, as if they had no intelligence to appreciate a worthy aim, no power of sympathising with a great design, no need of an interest in life and a worthy object on which to spend it, no share in the common cause. Yet such is the life with which, apart from Christ, we must perforce be content, doing the tasks appointed us with no sustaining consciousness that our work is part of a great whole working out the purposes of the Highest. Even such a spirit as Carlyle is driven to say: "Here on earth we are soldiers, fighting in a foreign land, that understand not the plan of campaign and have no need to understand it, seeing what is at our hand to be done,"--excellent counsel for slaves, but not descriptive of the life we are meant for, nor of the life our Lord would be content to give us.
To give us true freedom, to make this life a thing we choose with the clearest perception of its uses and with the utmost ardour, our Lord makes known to us all that He heard of the Father. What He had heard of the Father, all that the Spirit of the Father had taught Him of the need of human effort and of human righteousness, all that as He grew up to manhood He recognised of the deep-seated woes of humanity, and all that He was prompted to do for the relief of these woes, He made known to His disciples. The irresistible call to self-sacrifice and labour for the relief of men which He heard and obeyed, He made known and He makes known to all who follow Him. He did not allot clearly defined tasks to His followers; He did not treat them as slaves, appointing one to this and another to that: He showed them His own aim and His own motive, and left them as His friends to be attracted by the aim that had drawn Him, and to be ever animated with the motive that sufficed for Him. What had made His life so glorious, so full of joy, so rich in constant reward, He knew would fill their lives also; and He leaves them free to choose it for themselves, to stand before life as independent, unfettered, undriven men, and choose without compulsion what their own deepest convictions prompted them to choose. The "friend" is not compelled blindly to go through with a task whose result he does not understand or does not sympathise with; the friend is invited to share in a work in which he has a direct personal interest and to which he can give himself cordially. All life should be the forwarding of purposes we approve, the bringing about of ends we earnestly desire: all life, if we are free men, must be matter of choice, not of compulsion. And therefore Christ, having heard of the Father that which made Him feel straitened until the great aim of His life could be accomplished, which made Him press forward through life attracted and impelled by the consciousness of its infinite value as achieving endless good, imparts to us what moved and animated Him, that we may freely choose as He chose and enter into the joy of our Lord.
