But the conception of life derived from, and sustained by, God involves the idea of immortality. 'No work begun shall ever pause for death.'[15] To live in God is to live as long as God. The spiritual man pursues his way through conflict and achievement towards a higher and yet a higher goal, ever manifesting, yet ever seeking, the infinite that dwells in him. All knowledge and quest and endeavour, nay existence itself, would be a mockery if man had 'no forever.' Scripture corroborates the yearnings of the heart and represents life as a growing good which is to attain to ever higher reaches and fuller realisations in the world to {132} come. It is the unextinguishable faith of man that the future must crown the present. No human effort goes to waste, no gift is delusive; but every gift and every effort has its proper place as a stage in the endless process.[16] 'There shall never be lost one good! What was shall live as before.'[17] II The foregoing discussion leads naturally to the second aspect of the highest Good, the Ideal in its social or corporate form--_the kingdom of God_. Properly speaking, there is no such thing as an individual. As biologically man is only a member of a larger organism, so ethically he can only realise himself in a life of brotherhood and service. It is only within the kingdom of God and by recognition of its social relations that the individual can attain to his own blessedness. Viewed in the light of the mutual relation of its members the kingdom is a brotherhood in which none is ignored and all have common privileges and responsibilities; viewed in the light of its highest good it is the entire perfection of the whole--a hierarchy of interests subordinated to, and unified by, the sovereignty of the good in the person of God.[18] 1. By reason of its comprehensiveness the doctrine of the kingdom has been regarded by many as the most general conception of the ideal of Jesus. 'In its unique and unapproachable grandeur it dwarfs all the lesser heights to which the prophetic hopes had risen, and remains to this day the transcendent and commanding ideal of the possible exaltation of our humanity.'[19] The principles implicitly contained in the teaching of Jesus concerning the kingdom have become the common possessions of mankind, and are moulding the thoughts and institutions of the civilised world. Kant's theory of a kingdom of ends, Comte's idea of Humanity, and the modern conceptions of scientific and {133} historical evolution are corroborative of the teaching of the New Testament. Within its conception men have found room for the modern ideas of social and economic order, and under its inspiration are striving for a fuller realisation of the aspirations and hopes of humanity.[20]
