I have not read these words as a text, but as an introduction, to what I desire to say, as God shall help me, concerning the most recent manifestation of’ the Pentecostal power. I refer to the great work of God that is going on in Wales at this time; and I trust that something more than curiosity makes you desire to hear of this work, for I am not speaking with any intention to satisfy curiosity. I want now in the simplest way to speak to you, first, very briefly, and as far as it is possible, of what my own eyes have seen, my own ears heard, and my own heart felt.I do this in order that, we may ask finally, what are the lessons God would teach us in this day of His visitation? Yet I cannot help reverting, before going further, to the passage that I have read in your hearing. Peter stood in the midst of one of the most wonderful scenes that the world has ever beheld. When men said of the shouting multitude that they were drunk, Peter said, “No, those men are not drunken as ye suppose”; but “this is that,” which was spoken by the Prophet Joel. If anyone shall say to me, “What do you think of the Welsh Revival?” I say at once, “This is that.”
