Pastoral work is of immense importance, and all preachers should be diligent in performing it. But it cannot take the place of preaching, nor fully compensate for lack of power in the pulpit. The two help each other, and neither of them is able, unless supported by the other, to achieve the largest and most blessed results. When he who preaches is the sympathizing pastor, the trusted counselor, the kindly and honored friend of young and old, rich and poor, then “truths divine come mended from his lips,” and the door to men’s hearts, by the magical power of sympathy, will fly open at his word. But on the other hand, when he who visits is the preacher, whose thorough knowledge of Scripture and elevated views of life, whose able and impassioned discourses have carried conviction and commanded admiration, and melted into one the hearts of the multitude, who is accustomed to stand before them as the ambassador of God, and is associated in their minds with the authority and sacredness of God’s Word,–when he comes to speak with the suffering, the sorrowing, the tempted, his visit has a meaning and a power of which otherwise it must be destitute. If a minister feels himself specially drawn towards either of these departments of effort, let him also constrain himself to diligence in the other.
