The Welsh Revival 
I. A Narrative of Facts II. The Revival: Its Power and Source

I am a child of the revival of 1859-60. I have witnessed the Revival in South Wales, and it is borne in upon me that I must testify as to what I have seen and know.
I have been urged and entreated to speak in public on the subject. I have refused, although sorely tempted to comply. But though I am not physically strong enough to face the immense strain which public speaking always makes upon my nervous system, I cannot keep silent. Woe is me if I bear not my testimony, and bear it now! For never is it so true as in times of Revival that Now is the accepted time. Now is the day of salvation.
That is not a mere hackneyed text; it is a somewhat awe-inspiring fact. A fact, not a theory. The importance of the psychological moment so much insisted upon by Bismarck is as true in religion as in politics. It is the familiar truth, which all admit in other departments of life.
“There is a tide in the affairs of men
Which, taken at the flood, leads on to fortune.
Omitted, all the voyage of their life
Is bound in shallows, and in miseries.”
