Assurance (theology)

Early in his ministry Wesley had to defend his understanding of assurance. In 1738, Arthur Bedford had published a sermon in which he misquoted Wesley's teachings. Bedford had misunderstood Wesley as saying that a Christian could be assured of persevering in a state of salvation, the Reformed view. In a letter dated September 28, 1738, Wesley wrote, "The assurance of which I alone speak I should not choose to call an assurance of salvation, but rather (with the Scriptures), the assurance of faith. ...
