How do you measure influence? Is it tangible or theoretical? In my opinion, it is measured by visibly changed lives, especially when they span family and community, generations and geography. My father-in-law, Bert Vincent, had this kind of influence. From within the family circle and beyond, his legacy is one of evangelism, encouragement, passion and prayer. He inspired many to be active in the kingdom of God.

In Rwanda, the land of a thousand hills, a village in Kayenzi perches along the top of a ridge, overlooking the valley below. Green hills, dotted with rust-red roofs, disappear into the distance. The land is divided into small farms—about 90 percent of Rwandans depend on subsistence agriculture, growing only enough food to feed their families. Children cluster at communal water taps, filling yellow containers, smiling and waving at passing cars.
