And what, we may ask, produced this marvelous change? Simply the word of God brought home to their souls in the mighty power of the Holy Ghost. We have referred to the inspired account of the apostle's visit to Thessalonica. We are told that "he reasoned with them out of the Scriptures." He sought to bring their souls into direct contact with the living and eternal word of God. There was no effort to act on their feelings and imagination. All this the blessed workman judged to be utterly valueless. He had no confidence whatever in it. His confidence was in the word and Spirit of God. He assures the Thessalonians of this very thing in the most touching manner, in chap. ii. of his epistle. "For this cause," he says, "thank we God without ceasing, because, when ye received the word of God which ye heard of us, ye received it _not as the word of men_, but, as it is in truth, _the word of God_, which effectually worketh also in you that believe." This is what we may call a vital and cardinal point. The word of God, and that alone, in the mighty hand of the Holy Ghost, produced these grand results in the case of the Thessalonians, which filled the heart of the beloved apostle with unfeigned thanksgiving to God. He rejoiced that they were not linked on to him, but to the living God Himself, by means of His word. This is an imperishable link. It is as enduring as the Word which forms it. The word of man is as perishable as himself; but the word of the Lord endureth forever. The apostle, as a true workman, understood and felt all this, and hence his holy jealousy, in all his ministry, lest the souls to whom he preached should, in any way, lean upon him instead of on the One whose messenger and minister he was. Hear what he says to the Corinthians: "And I, brethren, when I came unto you, came not with excellency of speech or of wisdom, declaring unto you _the testimony of God_. For I determined not to know anything among you, save Jesus Christ, and Him crucified. And I was with you in weakness, and in fear, and in much trembling. And my speech and my preaching was not with enticing words of man's wisdom, but _in demonstration of the Spirit_ and of power; that your faith should not stand in the wisdom of men, but _in the power of God_" (1 Cor. ii. 1-5). Here we have true ministry--"the testimony of God," and "the demonstration of the Spirit"--the Word and the Holy Ghost. Nothing else is of any value. All mere human influence, human power, and the results produced by human wisdom or energy, are perfectly worthless--yea, positively mischievous. The workman is puffed up by the apparent results of his work paraded and talked of, and the poor souls that are acted upon by this false influence are deceived, and led into an utterly false position and false profession. In a word, the whole thing is disastrous in the extreme.
