Jesus tells us to love one another, always. But sometimes we may meet people who we believe are genuinely unloveable by any human standards. That is when we let God love them through us.
In a number of workshops, I have asked people whether they have had one or more experiences that they would identify as an experience of God and, if so, to share them in small groups. On average, 80 percent of the participants identify one or more and are eager to talk about them. They also frequently report that they had never before been asked that question in a church setting or given an opportunity to talk about it.
