was born on December 18, 1707, the 18th child out of 19 of Samuel and Susanna Wesley. The rector of Epworth in Lincolnshire, Samuel Wesley, was also a poet who passed on his poetic gifts to his son.
Charles followed his father and brother John into Anglican orders. In October 1735, the siblings sailed for Savannah in Georgia Colony in British America at the request of its governor, James Oglethorpe. There, Charles met a Mr. Bray, who he described as "a poor, innocent mechanic who knows nothing but Christ."
After returning to England, Charles converted from High Church to Evangelical Christianity on May 21, 1738 through a sister of Mr. Bray, Mrs. Turner. As she spoke to him about Christ, he picked up his Bible and opened to Psalm 40 v 3: "He hath put a new song, in my mouth, even praise unto our God." Three days later, John Wesley had the same conversion experience.
A year later, Charles Wesley wrote the hymn "O For A Thousand Tongues" to celebrate the first anniversary of his conversion. He penned it after a Moravian friend, Peter Bohler, remarked to him, "If I had a thousand tongues I would praise Christ with them all." The words set Wesley's heart aglow, and he penned the hymn with a full and thankful heart as a testimony of what Christ has done for him.
