"Now what do the waters represent? Hear it in Revelation 17:15, "... the waters which thou sawest,... are peoples, and multitudes, and nations, and tongues." His voice was as the sound of multitudes speaking. What is it? It is the judgment. For these are the voices of the multitudes of witnesses, who by the Holy Spirit all through the ages have testified to Christ and preached His Gospel. It will be the voice of every man rising in judgment against the sinner who would not take warning. The voices of the seven messengers will be heard loud and clear. Those faithful preachers who preached the saving power of Jesus, who preached water baptism in Jesus' Name, who preached the in-filling and power of the Holy Ghost, who stood with the Word more than they stood with their own lives; all of them were the voice of Jesus Christ by the Holy Ghost down through the ages."
