“Pastor,” we heard the conference speaker say, “your front door is the most important, but you can’t forget to pay attention to the back door.” That sounds like good advice, doesn’t it? Growth comes through the front door, but growth is retained by means of the back door. The voice of wisdom might be understood to say that depth of discipleship is best attained by keeping the back door closely guarded. (In case these terms are unfamiliar, the front door refers to people coming to your church for the first time while the back door refers to people quitting your church).
