Müller started out his life as a petty thief and a gambler. He turned his life around and studied divinity in the University of Halle and soon began preaching regularly in nearby churches. In 1828, Müller became the pastor of Ebenezer Chapel in Devon, England and married. During his time as the pastor here, he refused a regular salary and eliminated the practise of renting of church pews. Müller moved to Bristol in 1832 where he preached until his death.
In 1834, with no governmental support, he founded the Scriptural Knowledge Institution for Home and Abroad to aid Christian schools and missionaries and distribute the Bible. He never made requests for financial support and took only unsolicited gifts, and by the time of his death, it had supported the orphanages and distributed hundreds of thousands of Bibles and other religious texts. It also supported other “faith missionaries” around the world, and the work continues to this day.
His charges had a tight schedule. They were well-dressed, well-fed and well-educated. In 1871 an article in The Times stated that since 1836, 23,000 children had been educated in his schools and many thousands had been educated in other schools at the expense of the orphanage. In 1875, at the age of 70, Müller began missionary travels, preaching (in English, French, and German) in the US, India, Australia, Japan, China, and nearly 40 other countries. For 17 years, he travelled over 200,000 miles. In 1898, he died in England. After his life, his work was continued by The George Müller Foundation, which was renamed The George Müller Charitable Trust in 2009.
