John Wesley wrote extensively on the use of money, the danger of riches, and the importance of giving. For Wesley, all things belong to God. This changes how we perceive the manner by which we earn money and save money, causing us to do so in appropriate ways. And in changes how we spend money, making us more responsible, and shapes how we give money. Wesley valued industrious and productive work, but he believed that acquiring money does not provide a profound enough life purpose to sustain the human spirit. When he wrote, “Earn all you can, save all you can, and give all you can,” he drew an unbreakable link between acquisition and generosity, inviting us to use our material wealth to deepen our relationship with God and to increase our positive impact for God’s purposes.
