But why should unity be the ultimate desire of Christ, the highest point to which the Saviour's wishes for mankind can reach? Because spirit is that which rules; and if we be one with God in spirit the future is ours. This mighty universe in which we find ourselves, apparently governed by forces compared to which the most powerful of human engines are weak as the moth--forces which keep this earth, and orbs immeasurably larger, suspended in space,--this universe is controlled by spirit, is designed for spiritual ends, for ends of the highest kind and which concern conscious and moral beings.
It is as yet only by glimpses we can see the happiness of those who are one with God; it is only by inadequate comparisons and with mental effort we can attain to even a rudimentary conception of the future that awaits those who are thus eternally blessed. Of them well may Paul say, "All things are yours; for ye are Christ's, and Christ is God's." It is for Christ all things are governed by God; to be in Him is to be above the reach of catastrophe--to be, as Christ Himself expresses it, beside Himself on the throne, from which all things are ruled. Having been attracted by His character, by what He is and does, and having sought here on earth to promote His will, we shall be His agents hereafter, but in a life in which spiritual glory irradiates everything, and in which an ecstasy and strength which this frail body could not contain will be the normal and constant index of the life of God in us. To do good, to utter by word or deed the love and power that are in us, is the permanent joy of man. With what alacrity does the surgeon approach the operation he knows will be successful! with what pleasure does the painter put on canvas the idea which fills his mind and which he knows will appeal to every one who sees it! And whoever learns to do good by partaking of God's spirit of communicative goodness will find everlasting joy in imparting what he has and can. He will do so, not with the feeble and hesitating mind and hand which here make almost every good action partly painful, but with a spontaneity and sense of power which will be wholly pleasure; he will know that being one with God he can do good, can accomplish and effect some solid and needful work. Slowly, very slowly, is this arrived at; but time is of no consequence in work that is eternal, so long only as we are sure we do not idly miss present opportunities of learning, so long only as we know that our faces are turned in the right direction, and that a right spirit is in us.
If there lingers in our minds a feeling that the end Christ proposes and utters as His last prayer for men does not draw us with irresistible force, it might be enough to say to our own heart that this is our weakness, that certainly in this prayer we do touch the very central significance of human life, and that however dimly human words may be able to convey thoughts regarding eternity we have here in Christ's words sufficient indication of the one abiding end and aim of all wisely directed human life. Whatever the future of man is to be, whatever joy _life_ is to become, in whatever far-reaching and prolonged experiences we are to learn the fruitfulness and efficacy of God's love, whatever new sources and conditions of happiness we may in future worlds be introduced to, whatever higher energies and richer affections are to be opened in us, all this can only be by our becoming one with God, in whose will the future now lies. And it may also be said, if we think this the prayer of One who was not in the full current of actual human life, and had little understanding of men's ways, that this prayer is fulfilled in very many who are deeply involved and busily occupied in this world. They give their mind to their employment, but their heart goes to higher aims and more enduring results. To do good is to them of greater consequence than to make money. To see the number of Christ's sincere followers increasing is to them truer joy than to see their own business extending. In the midst of their greatest prosperity they recognise that there is something far better than worldly prosperity, and that is, to be kept from the evil that is in the world and to extend the knowledge of God. They feel in common with all men that it is not always easy to remember that great spiritual kingdom with its mighty but unobtrusive interests, but they are kept by the Father's name, and they do on the whole live under the influence of God and hoping in His salvation. And it would help us all to do so were we to believe that Christ's interest in us is such as this prayer reveals, and that the great subject of His intercession is, that we be kept from the evil that is in the world and be helpful in the great and enduring work of bringing into truer fellowship men's lives and God's goodness. Alongside of all our profitless labour and unworthiness of aim there runs this lofty aim of Christ for us; and while we are greedily following after pleasure, or thoughtlessly throwing ourselves into mere worldliness, our Lord is praying the Father that we be lifted into harmony with Him and be used as channels of His grace to others.
