Simply put, the Metric Black Hole is the idea that there are many things that we do for which we do not have an accurate measurement of how they contribute to the bottom line.

We’d been on the road in South Asia for three weeks. We’d covered thousands of kilometers and met hundreds of people. The purpose was to hear their stories and experience the life of a movement of God.
