Last week, I was preparing to do some seminars on outreach. I pulled out Flavil Yeakley’s Why Churches Grow, a book that was published in 1979.

Yeakley conducted a nationwide survey of growth patterns among Churches of Christ. He looked at attendance numbers from the 1960s and 1970s, then conducted surveys seeking to answer two questions:

1. Why do some churches grow?
2. Why are some people receptive to the gospel?

I found a lot of what he had to say to be surprisingly relevant. Well, I say surprisingly. Actually I’m not surprised. The basic truths about how to reach out to others haven’t changed all that much.

You see, Yeakley found that the most significant factor in someone coming to be a member of a church had little to do with church programs or church staff. The most significant factor was relationships. Other research says that 75-90% of converts report that the main influence, or one of the main influences, was a friend or relative. Yeakley’s work backed that up.

In his book, Yeakley looked at differing views of evangelism among those reaching out. Some saw evangelism as a transmission of information. Others used a manipulative monologue, steering their listeners through a set presentation. Others approached the process as an open dialogue. What Yeakley found was startling in how clear-cut the results were.

• Those who saw evangelism as a transmission of information were highly unsuccessful. In Yeakley’s study, evangelists using this style had converted only 35 people out of 240 studies. An additional 25 had dropped out soon after joining the church. The rest did not respond positively to the evangelist.
• When the worker used a type of manipulative monologue, they had 36 converts out of 303 studies. With this group, the dropout rate was extremely high: 209 out of 303. These were people who were initially convinced, then fell away. The rest did not accept the message at all.
• With the third group, those using a style of open dialogue, Yeakley found 169 conversions out of 177 studies. An additional 5 people were in the “dropout” category, and only 2 completely rejected the message.

I don’t think that’s changed, from what I’ve seen here and in Latin America. Relationships are key. It’s not about methods. It’s not about programs. It’s not even about worship styles. It’s about people sharing God’s message with other people.
