"Congo is over 90% Christian, Kelley says, but "It's the old adage in Africa where they say 'Christianity is a mile wide and an inch deep.'
"It comes back to the original instruction [Jesus] told us. He [didn't tell] us 'Make converts.' He said, 'Go and make disciples'! That's depth, and that's what Congo really lacks today. If you were to say, what's the one issue, it's that the church lacks disciple-making."
