Ancient asceticism, in demanding for the ministry a hidden life of communion with God, gave voice not only to one of the profoundest intuitions of the Christian consciousness, but also to one of the clearest teachings of Scripture. The men who deal with spiritual things must themselves be spiritual. Our age, while rightly rejecting a perverted asceticism, is tending to the opposite error. It is intensely practical. "Action!" is its watchword. This practicalness often becomes mere narrowness and shallowness. It overlooks the profounder laws of the Christian life. Spiritual force comes from within, from the hidden life of God in the soul. It depends, not on mere outward activities, but on the Divine energies acting through the human faculties, God working through the man, the Holy Ghost permeating, quickening all the powers of the preacher, and speaking by his voice to the souls of the people. The soul's secret power with God thus gives public power with men, and the mightiest influences of the pulpit often flow from a hidden spring in the solitude of the closet; for a sermon is not the mere utterance of man: there is in it a power more than human. Its vital force comes from the Holy Spirit. Jesus said: "It is not _ye_ that speak, but the Spirit of your Father that speaketh in you" (Matt. x. 20). Its spiritual energy springs from something deeper than logic and rhetoric. As Bushnell has well said: "Preaching is nothing else than the bursting out of life which has first burst in or up from where God is among the soul's foundations." Such was the teaching of Christ. In His farewell words to His disciples He promised "another Comforter"--one who should take His place among them and abide with them for ever. As He had walked with them an Instructor, Friend, Helper, so after His departure the Holy Spirit should dwell among them, teaching, inspiring, guiding them, a true and living Divine Presence ever with them and mighty to help. Blessed as His own bodily presence had been, the presence of the Holy Spirit was of still higher moment, for He declared that it was better for them that He Himself depart and the Spirit come; for the Spirit, whose office it is to take of Christ and show Him, should reveal the Christ-presence within them in accordance with His promise: "He that loveth Me shall be loved of My Father, and I will love him, and _will manifest Myself to him_" (John xiv. 21); "I will not leave you comfortless; _I will come to you_" (John xiv. 18). Without this Divine Helper He expressly forbade their entrance on the ministry, and as His last charge before He ascended He said, "Tarry ye in the city of Jerusalem until ye be endued with power from on high" (Luke xxiv. 49).
