Some there are who speak disparagingly of the blessed and holy work of evangelization. We tremble for them. We feel persuaded they are not in the current of the Master's mind, and hence we utterly reject their thoughts. It is to be feared that their hearts are cold in reference to an object that engages the heart of God. If so, they would need to humble themselves in His presence, and seek to get their souls restored to a true sense of the magnitude, importance and interest of the grand question before us. At least let them beware of how they seek to discourage and hinder others whose hearts the Lord has moved to care for precious, immortal souls. The present is most assuredly not the time for raising difficulties, and starting questions which can only prove stumbling-blocks in the pathway of earnest workers. It becomes us to seek in every right way to strengthen the hands of all who are endeavoring, according to their measure, to publish the glad tidings, and make known the unsearchable riches of Christ. Let us see that we do so, so far as in us lies; and above all things, let us never utter a sentence calculated to hinder any one in the blessed work of winning souls to Christ. But we must draw this paper, and this series of papers, to a close. We might do so here, were it not that there is one more point in our subject which we feel must not be omitted, and that is the _power_ by which "the great commission" was to be carried out. To leave this out would be a great defect, a serious blank indeed; and we are the more anxious to notice it, inasmuch as the special form in which the power was communicated links itself, in a very remarkable way, with that which has been before us in this paper. If the _sphere_ was to be "all nations," the _power_ must be adapted thereto; and, blessed be God, so it was. Our blessed Lord, in closing His commission to His disciples, said, "And ye are witnesses of these things. And behold, I send the promise of My Father upon you; but tarry ye in the city of Jerusalem, until ye be endued with power from on high." This promise was fulfilled, this power was communicated on the day of Pentecost. The Holy Ghost came down from the ascended and glorified Man, to qualify His servants for the glorious work for which He had called them. They had to "tarry" until they got the power. How could they go without it? Who but the Holy Ghost could speak adequately of the love of God, of the person, work and glory of Christ? Who but He could enable any one to preach repentance and remission of sins? Who but He could properly handle all the weighty subjects comprehended in "the great commission?" In a word, the power of the Holy Ghost is absolutely essential in every branch of Christian service, and all who go to work without it will find it to be barrenness, misery, and desolation.
