In Memory Of Him Whose Name We Cannot Remember

Talking about a friend of his, Paul Newsham related the following story: The Holy Spirit keeps a testimony in different cultures. 

One missionary went to an African tribe that had had little contact with white people. When he arrived, they were in the middle of a ceremony which was remarkably like our Communion. Because he was a linguist, he was able to understand a lot of what was said. 

When they got to the end they said, "We do this in memory of Him whose name we cannot remember." He stood up and said, "I want to tell you His name. His name is Jesus."
