I look to my Incarnate God, ’Till He His work begin, And wait ’till His redeeming blood Shall cleanse me from all sin. His great salvation I shall know, And perfect liberty; Onward to sin he cannot go, Whoe’er abides in Thee: Added to the Redeemer’s fold, I shall in Him rejoice, I all His glory shall behold, And hear my Shepherd’s voice. O that I now the voice might hear That speaks my sins forgiven! His word is past to give me _here_ The inward pledge of heaven. His blood shall over all prevail And sanctify the unclean; The grace that saves from future hell Shall save from present sin. In no part of the kingdom was the Evangelical Revival more influential than in Wales. Whitefield, Howell Harris, and, perhaps more than all, Lady Huntingdon, were the controlling minds, and they led the people of the Principality to the Calvinistic rather than to the Wesleyan Methodists. The quaint poetry of Vicar Rees Prichard’s _Welshman’s Candle_ and the Psalms of Archdeacon Prys seem to have been the songs of the Welsh Church until William Williams of Pantycelyn arose—a great light, well worthy to be called the Watts of Wales. His father was deacon of an Independent Church, which at one time met ‘in a cave during the hours of twilight,’ for fear of their enemies. Williams himself was studying medicine, and had no thought of the ministry. One Sunday morning, as he passed through Talgarth in Breconshire, he went into the parish church. After the service the congregation gathered in the churchyard, and Howell Harris, standing on a tomb-stone, preached with the Holy Ghost and with power. That was the hour of Williams’s conversion. He prepared for the ministry of the Established Church, and was ordained deacon in 1740. He acted as curate of two small parishes for three years, and then, drawn into the current of the Revival under the influence of Whitefield, David Rowlands, and Howell Harris, he became an earnest evangelist, travelling throughout the Principality. His hymn-writing is said to have been occasioned by a challenge of Howell Harris to the Welsh Calvinistic preachers to write better hymns than their congregations then possessed. He wrote hymns by the hundred, and they won an immediate and enduring popularity in Wales. ‘What Paul Gerhardt has been to Germany, what Isaac Watts has been to England, that and more has William Williams of Pantycelyn been to Wales.’[169] He was a great favourite with Lady Huntingdon, at whose suggestion he prepared a volume of hymns for Whitefield’s Orphan House. In this work, entitled _Gloria in Excelsis_, some of his best hymns appeared. In modern hymn-books he is known by two hymns— Guide me, O Thou great Jehovah! and O’er those gloomy hills of darkness.
