Congregations seeking to transform are faithful to God first and others second. They do not compromise their faithfulness to God to create a successful congregation. They do not compromise their faithfulness to God by compromising their doctrinal convictions in order to reach people.
Yet they do understand the difference between doctrinal convictions consistent with their understanding of the living Word of God, and cultural convictions that may not be based in sound theology. It is likely at the point of cultural convictions where it is the toughest to keep faithfulness to God first. But they willingly place God first.
