While crossing a bridge in London, John Wesley stumbled and sprained his ankle. Some friends carried him to the house of Mrs. Mary Vazielle on Threadneedle Street. She was a widow with several children. She cared for Wesley and his response to her concern was to ask her to marry him. If we were writing fiction we might say that the sprained ankle was God's providential way to bring those people together.
But the marriage was a disaster, and Mary finally left John. Had Wesley consulted with his brother Charles, and asked for the prayers of the brethren, he might have avoided that unfortunate situation. Mary was accustomed to her quiet home, and it was difficult for her to travel with her husband and stay in uncomfortable inns. It is unfortunate that Mary was not content just to ignore John's ministry; she actually opposed it. She gave certain personal letters to his enemies and even made additions to them that made them worse! Once she even pulled her husband around on the floor by his hair! "I felt as though I could have knocked the soul out of her!" one of Wesley's friends said.
Wesley concluded that his unhappy marriage encouraged him to work harder and not complain about missing the comforts of a home. Certainly it encouraged him to be away from home more!
