Whether this event in Montgomeryshire was a preparation for what took place six or seven years later is a suggestive question only, but when the wave of spiritual power from the great American revival of 1857-8 reached England, its first messenger to Wales, Rev. H.R. Jones, a Wesleyan, had only to drop the spark that "lit a prairie fire." The reformation, chiefly under the leadership of Mr. Jones and Rev. David Morgan, a Presbyterian, with their singing bands, was general and lasting, hundreds of still robust and active Christians today dating their new birth from the Pentecost of 1859 and its ingathering of eighty thousand souls. A favorite hymn of that revival was the penitential cry,-- _O'th flaem, O Dduw! 'r wy'n dyfod_, --in the seven-six metre so much loved in Wales. Unto Thy presence coming, O God, far off I stand: "A sinner" is my title, No other I demand. For mercy I am seeking For mercy still shall cry; Deny me not Thy mercy; O grant it or I die! * * * * * I heard of old that Jesus, Who still abides the same, To publicans gave welcome, And sinners deep in shame. Oh God! receive me with them, Me also welcome in, And pardon my transgression, Forgetting all my sin. The author of the hymn was Thomas Williams of Glamorganshire, born 1761; died 1844. He published a volume of hymns, _Waters of Bethesda_ in 1823. The Welsh minor tune of "Clwyd" may appropriately have been the music to express the contrite prayer of the words. The living composer, John Jones, has several tunes in the Welsh revival manual of melodies, _Ail Attodiad_.
