John Wesley, the founder of the Methodist movement, wrote this on May 24, 1738:

In the evening I went very unwillingly to a society in Aldersgate Street,1 where one was reading Luther’s preface to the Epistle to the Romans.2 About a quarter before nine, while he 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, 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.
