In his latest book, In Search of the Common Good, Jake Meador writes:

Love also must be faithful because when we love we do not simply will the person’s good a single time and then stop. We see this in marriage and parenting, of course, but friendship should be faithful as well. In the aftermath of my father’s injury, one of the qualities we most appreciated in many of my parents’ friends was their fidelity. One woman from the church is still mowing their yard once a week over three years after Dad’s injury. We could depend on them not simply on the day of the injury but a month later, a year later, three years later.
