Something to keep in mind when opening small groups and planting churches (among different cultures) is that people feel most at home and accepted when they are around people who are like them and things that are familiar to them. In other words, people (generally) will be more at ease when they don’t have to cross- “out” of their culture to be a welcome part of a group. This might also be called the principle of homogenity. However, the reason that I call it the Ingress principle is because of the type of welcome that is involved. A Gospel welcome involves believers who are culturally like the guests with accompanying tastes, sounds, colors, smells, music, and even slang (or ways to say things that are particular to their culture).
If you have a group of Germans, it will be difficult to welcome Chinese people — until there are one or two Chinese who are spending time with the German group AND the Germans make efforts to really affirm, adapt, and understand the Chinese. This really takes some time, energy, and understanding. It sounds missional, doesn’t it?
Remember, in this illustration we are not trying to conform the Chinese to the Germans even though, at first, the Germans are the predominant group. We are saying, because of the Gospel, the Germans are willing to be uncomfortable and uncultural in their way of life for the sake of the Chinese welcoming other Chinese.
