John Wesley in his June 1742 journal recounts a question from a woman that caught him by surprise. She asked:
Ought not a Minister of Christ to do three things: First, To preach his Law, in order to convince of sin; Then, To offer free pardon, through faith in his blood, to all convinced sinners; And, in the Third place, To preach his Law again, as a rule for those that believe? I think, if one does otherwise, he is no true Minister of Christ. He divides what God has joined, and cannot be said to preach the whole Gospel.
Wesley’s surprise, I assume, was that she asked one of those questions that completely confirmed what he believed and practiced.
