How, then, shall the pastor maintain an inner life such that he shall be "endued with power from on high" and God shall speak through him to the souls of men? In answer this I suggest as a means of chief importance: I. THE HABITUAL PRACTICE OF SECRET PRAYER.--For prayer is the bond which links the Divine power with the human. It is the channel through which God pours His life into the soul. It is the uplifted hand of man's weakness taking hold on God's strength. It calls down from heaven the sacred fire, which alone may kindle the preacher's sacrifice. It has the most vital relations to the character and work of a pastor. 1. _The relation of secret prayer to the spirit and purpose of the ministry._ Special dangers beset the pastor. The most sacred services, from their frequent recurrence, may come to be performed in a perfunctory spirit, and his life may thus degenerate into mere professionalism. Unconsciously he comes to meditate, read, and even pray with a view only to others and its effect on others. The sense of his personal relation to God is lost. As a public speaker a desire for popularity may unduly influence his preaching, and conspicuous position tempt his ambition, obscuring his vision of the great end of his ministry--the honor of Christ and the salvation of souls. The very respect which his office secures may foster spiritual pride and make him insensible to his defection in heart from God. Few men are environed by such subtle and powerful seductions to a false life as a Christian minister, and against these only a vivid consciousness of his high calling is an adequate safeguard. He is God's ambassador, receiving his commission and his message, not from men, but from the Sovereign of heaven and earth. The souls of his congregation are entrusted to him, and the words he is charged to speak are the words of God's saving power. "In them that are saved" he is "a savor of life unto life," but "in them that perish" "a savor of death unto death" (2 Cor. ii. 15, 16). If faithful to his trust, he "shall shine as the brightness of the firmament" and "as the stars for ever and ever" (Dan. xii. 3); if unfaithful, the blood of souls will be found on him in the day of God's inquisition. Now, only a distinct realization of these responsibilities as an ever-present, living force pervading his spirit will hold the minister in his inmost life true to Christ and to his work.
