D.L. Moody emphasizes that when individuals are filled with the Holy Spirit, they focus on preaching Christ rather than themselves. He illustrates this through various biblical figures, such as Zacharias, who proclaimed God's redemption, and Peter, who preached powerfully at Pentecost. Moody asserts that the Holy Spirit empowers believers to magnify the Word of God, leading to the spread of the Gospel in every corner of society. He encourages the congregation to seek the Spirit's filling to effectively share the message of salvation. Ultimately, the sermon calls for a commitment to preaching Christ as revealed in Scripture.

Then you will find all through the Scriptures, when men were filled with the Holy Spirit, they preached Christ and not themselves. They preached Christ and Him crucified. It says in the first chapter of Luke, 67th Verse, speaking of Zacharias, the father of John the Baptist: "And his father, Zacharias, was filled with the Holy Ghost, and prophesied, saying: Blessed be the Lord God of Israel, for He hath visited and redeemed His people, and hath raised up an horn of salvation for us in the house of His servant David. As He spake by the mouth of His Holy prophets, which have been since the world began." See, he is talking about the Word. If a man is filled with the Spirit, he will magnify the Word; he will preach the Word, and not himself; he will give this lost world the Word of the living God. "And thou, child, shalt be called the prophet of the Highest; for thou shalt go before the face of the Lord to prepare His ways. To give knowledge of salvation unto His people by the remission of their sins, through the tender mercy of our God, whereby the day-spring from on high hath visited us. To give light to them that sit in darkness and in the shadow of death, to guide our feet into the way of peace. And the child grew and waxed strong in spirit, and was in the deserts till the day of his showing unto Israel." And so we find again that when Elizabeth and Mary met, they talked of the Scriptures, and they were both filled with the Holy Ghost, and at once began to talk of their Lord. We also find that Simeon, as he came into the temple and found the young child Jesus there, at once began to quote the Scriptures, for the Spirit was upon him. And when Peter stood up on the day of Pentecost, and preached that wonderful sermon, it is said he was filled with the Holy Ghost, and began to preach the Word to the multitude, and it was the Word that cut them. It was the sword of the Lord and Peter, the same as it was the sword of the Lord and Gideon. And we find it says of Stephen, "They were not able to resist the spirit and wisdom by which he spake." Why? Because he gave them the Word of God. And we are told that the Holy Ghost came on Stephen, and none could resist his word. And we read, too, that Paul was full of the Holy Spirit, and that he preached Christ and Him crucified, and that many people were added to the Church. Barnabas was full of faith and the Holy Ghost; and if you will just read and find out what he preached, you will find it was the Word, and many were added to the Lord. So that when a man is full of the Spirit, he begins to preach, not himself, but Christ, as revealed in the Holy Scriptures. The disciples of Jesus were all filled with the Spirit, and the Word was published; and when the Spirit of God comes down upon the Church, and we are anointed the Word will be published in the streets, and in the lanes, and in the alleys; there will not be a dark cellar nor a dark attic, nor a home where the Gospel will not be carried by some loving heart, if the Spirit comes upon God’s people in demonstration and in power.
