But without this Presence great gifts and profound and accurate learning are without avail in the salvation of men. We often see men with great natural powers, splendidly trained, and equipped with everything save this fiery baptism, and they labour and preach year after year without seeing a soul saved. They have spent years in study; but they have not spent a day, much less ten days, fasting and praying and waiting upon God for His anointing that should fill them with heavenly wisdom and power for their work. They are like a great gun loaded and primed, but without a spark of fire to turn the powder and ball into a resistless lightning bolt. It is fire men need, and that they get from God in agonising, wrestling, listening prayer that will not be denied; and when they get it, and not till then, will they preach with the Holy Ghost sent down from Heaven, and surely men shall be saved. Such preaching is not foolish. The Holy Spirit makes the word alive. He brings it to the remembrance of the preachers in whom He abides, and He applies it to the heart of the hearers, lightening up the soul as with a sun until sin is seen in all its hideousness, or cutting as a sharp sword, piercing the heart with resistless conviction of the guilt and shame of sin. Peter had no time to consult the Scriptures and prepare a sermon on the morning of Pentecost; but the Holy Spirit quickened his memory, and brought to his mind the Scriptures appropriate to the occasion. Hundreds of years before, the Holy Spirit, by the mouth of the prophet Joel, had foretold that in the last days the Spirit should be poured out upon all flesh, and that their sons and daughters should prophesy. And the same Spirit that spoke through Joel now made Peter to see and declare that this Pentecostal baptism was that of which Joel spoke. By the mouth of David He had said: "Thou wilt not leave My soul in hell, neither wilt Thou suffer Thy Holy One to see corruption"; and now Peter, by the inspiration of the same Spirit, applies this Scripture to the resurrection of Jesus, and so proves to the Jews that the One they had condemned and killed was the Holy One foretold in prophecy and psalm. And so to-day the Holy Spirit inspires men who receive Him to use the Scriptures to awaken, convict, and save men.
