In other words, Paul wishes them to understand that, after all, the only sure test of a man's Christianity is his actual submission to Christ. No wonderful works he may accomplish in the Church or in the world prove his possession of Christ's Spirit. "Many will say to Me in that day, Lord, Lord, have we not prophesied in Thy name, and in Thy name have cast out devils, and in Thy name done many wonderful works? And then will I profess unto them, I never knew you; depart from Me, ye that work iniquity." A man may gather and edify a large congregation, he may write ably in defence of Christianity, he may be recognised as a benefactor of his age, or he may be considered the most successful of missionaries, but the only test of a man's claim to be listened to by the Church is his actual submission to Christ. He will seek not his own glory, but the good of men. And as to the gifts themselves, they should be no cause of discord, for they have everything in common: they have their source in God; they are for Christ's service; they are forms of the same Spirit. "There are diversities of gifts, but the same Spirit. And there are differences of administrations, but the same Lord. And there are diversities of operations, but it is the same God which worketh all in all." The new life then introduced by Christ into the individual and society was found to assume various forms and to suffice for all the needs of human nature in this world. Paul delighted to survey the variety of endowment and faculty which appeared in the Church. Wisdom, knowledge, faith, power to work miracles, extraordinary gifts of exhortation or prophecy and also of speaking in unknown tongues, capacity for managing affairs and general helpfulness--these and other gifts were the efflorescence of the new life. As the sun in spring develops each seed according to its own special kind and character, so this new spiritual force develops in each man his most intimate and special character. Christian influence is not an external appliance that clips all men after one pattern as trees in an avenue are clipped into one shape; but it is an inward and vital power which causes each to grow according to his own individuality, one with the rugged irregularity of the oak, another with the orderly richness of the plane. Variety in harmony is said to be the principle of all beauty, and it is this which the Divine Spirit in man produces. Individual distinctions are not obliterated, but developed and directed for the service of the community. At one in their allegiance to Christ, bound into one body by common affections, beliefs, and hopes, and aiming at the advancement of one cause, Christians are yet as different as other men in faculty, in temperament, in attainment.
