The Methodist Church was founded by John Wesley, an Anglican Minister. Following a difficult and discouraging mission trip to America, he questioned his faith. In 1738, at the age of 34, John Wesley attended an evening worship service in London which moved him deeply. In his journal, Wesley described his "Aldersgate experience:"
In the evening I went very unwillingly to a society in Aldersgate Street, where one was reading Luther's preface to the Epistle to the Romans. About a quarter before nine, while the leader was describing the change which God works in the heart through faith in Christ, I felt my heart strangely warmed. I felt I did trust in Christ alone for salvation; and an assurance was given me that He had taken away my sins, even mine, and saved me from the law of sin and death.
