Another church planting principle that we’ve noticed through the years has been that believers who are maturing in the Faith also broaden their acceptance of other people from different cultures. Whereas, in the Ingress Principle, people feel more welcome with others who are like them, this principle says that believers mature toward people who are unlike themselves. So, a church should seek to provide opportunities to integrate the cultures (that are welcoming others) into a Christ-centered, alternative culture. People usually need to be warmly-welcomed and meet Jesus before they begin to appreciate and care for others that are different than they are. At the same time, we don’t want to leave the church body to be isolated into separate cultures because the fullest expression of the Gospel will be lost and enculturated back into a certain people group.
For example, in the Ingress Principle, I mentioned a group of Chinese people who are being welcomed by a group of Germans who are believers. In time (could be long or short-term), when more Chinese people are also saved, they will come to see more of Jesus in the Germans and appreciate them as brothers and sisters. This will happen not just because they’re Germans, but because they are of Jesus. They will have a deep appreciation for the Germans because the Germans originally showed them the love of Jesus. So then, we want the Chinese to be together with the Germans so that, altogether, they can simply be Christians in God’s family. These principles of welcoming (ingress) and maturing (integration) will repeat themselves through the joy of outreach and evangelism.
