Sunday School Closes the Back Door—Research Proves It!

As America has received immigrants throughout our nation’s history, one great challenge for these new residents is how to assimilate into a new culture. Our missionaries often face the same difficulty as they take the gospel to other countries. There is a new language to learn, new attitudes to adjust to, and even new customs to learn. A similar thing happens as God brings new people into His church. People often have difficulty felling like they fit in.

In the work of the church, one of our greatest challenges is good assimilation—that is, making people feel they are really part of the church family and making them feel they are accepted into the culture of our church. Without a doubt, studies have demonstrated time and again, that Sunday School is still one of the best ways to make people feel they belong and to close the “back door” of the church.

Thom S. Rainer, in his book High Expectations writes the following findings from his research, "The new Christians who immediately became active in the Sunday School were five times more likely to remain in the church five years later (we did not include those who moved to another community or those who died in the "dropout" category)." The studies conducted by LifeWay have concluded that five years after joining a church, those active in Sunday School are still active church members 83% of the time. Those active in Worship only are still active five years later only 16% of the time.

This book also has a section that states, "In the 1980s I had become a 'Sunday School skeptic.' Any lingering doubts I had about Sunday School were erased when my research team… conducted a study of 576 churches in America. One would think that I would have no surprise when the strength of the Sunday School became evident in yet another research project. This time, however, the overwhelmingly positive response regarding the Sunday School surprised me. No assimilation methodology came close to Sunday School in effectiveness."

Dr. Rainer, continues, "The research is clear if not overwhelming. Sunday School is the most effective assimilation methodology in evangelistic churches today. But the mere existence of a Sunday School does not produce assimilation. Sunday School works. But only if we work Sunday School. We have known that Sunday School is a vital component of the past for American churches. Its history is almost as old as our nation itself. But more and more the research indicated that Sunday School is not only our past, it is our future as well. And we who are leaders in the church will ignore this reality to our churches' peril."

It makes no sense to ignore the reality that if people attend worship only that they go out the back door almost as quickly as they come in the front door. The more people who are involved in Sunday School, the stronger our church will be now, and in the future.
