H M S Richard's 1957 sermon titled "The Tongue of Fire"
The Tongue of Fire
"And there appeared unto them
cloven tongues like as of fire
and it sat upon each of them." (Acts 2:3).
A great many people did not like the preaching of Peter on the day of Pentecost. Lots of people today wouldn't like it. His sermon would be considered dry by many who do not like preachers to make them go to the trouble of thinking. . . . Lots of people don't like preachers who make them think about what they are saying.
But the day of Pentecost is come. Peter begins to preach. The Holy Spirit is present with mighty power. Peter's sermon is no more than quoting from the Word of God and reasoning upon them. Yet as he continues, the tongue of fire by degrees begins to burn its way into the feelings of the great multitude. They are arguing among themselves in various languages as to what is the matter with these men. Some think they are drunk. But, as Peter preaches, the tongue of fire does its work. The murmuring ceases. The mob becomes the congregation. The words rush on like a stream of fire. First one coating of prejudice is burned through, then another, and another; and at last the fire cuts through the innermost covering of prejudice that lies upon the heart. It burns away and now the message touches the very soul of man. There seems to be one mind in the congregation. That's the way it is in preaching with the Holy Spirit's power -- that one mind takes control of the congregation.
