Without such faith we would not even consider committing ourselves to his direction. But trust demands knowledge. Some people seem to think faith is merely accepting what we cannot know. They think of faith as a shabby substitute for certain knowledge. That's not the way it is at all.
True faith is built on accurate knowledge.
If we do not know someone, we will find it very difficult to trust him. Let me illustrate. My father was one of the first white men to visit the Auca Indians after Rachel Saint and Betty Elliot had settled in that tribe's territory and had begun working with them. While Dad was there, Kimo, one of the tribesmen who had participated in the murder of the five missionary men, offered to take him out into the jungle to show him how the Indians hunt monkeys with blow guns. Off they went, just the two of them.
