Step-by-step explanation:
John Wesley, along with his brother Charles, went on a trip to the New World in the 1730s as missionaries. They traveled to the colonies to engage in public service and missionary work. During their trip, they encountered Moravian passengers and associated with Moravians in England, which led to a deep religious conversion for both brothers. This conversion prompted them to preach about a personal, emotional relationship with God. Their preaching of this message continued when they returned to the colonies, influencing many people and contributing to the Great Awakening.
