It is surely no illegitimate application of the mind of Christ if we see in His teaching concerning the kingdom a great social ideal to be realised by the personal activities and mutual services of its citizens. It finds its field and opportunity in the realm of human society, and is a good to be secured in the larger life of humanity. This ideal, though only dimly perceived by the early Church, has become gradually operative in the world, and has been creative of all the great liberating movements in history. It lay behind Dante's vision of a spiritual monarchy, and has been the inspiring motive of those who, in obedience to Christ, have wrought for the uplifting of the hapless and the down-trodden. It has been the soul of all mighty reformations, and is the source of that conception of a new social order which has begun to mean so much for our generation. Loyalty to the highest and love for the lowest--love to God and man--these are the marks of the men of all ages who have sought to interpret the mind of Christ. Mutual service is the law of the kingdom. Every man has a worth for Christ, therefore reverence for the personality of man, and the endeavour to procure for each full opportunity of making the most of his life, are at once the aim and goal of the new spiritual society of which Christ laid the foundations in His own life and ministry. Everything that a man is and has, talents and possessions of every kind, are to be used as instruments for the promotion of the kingdom of God. 'For life, with all it yields of joy and woe, And hope and fear . . . Is just our chance o' the prize of learning love.' {139}
