From Darrell Guder in TREASURES IN CLAY JARS:
It may seem more than obvious that the Bible should stand at the center of the missional church. Virtually every Christian tradition affirms the centrality of Scripture to the Christian church. In theory at least, the sermon preached every Sunday is a proclamation of the biblical word. Certainly all of the congregations under review would make such affirmations and expect such preaching from their ministers.
There is a problem, however, It is possible to be biblically centered, to expect and to experience biblical preaching, and not to be a church that acknowledges, much less practices, its missional calling. This is the crisis and the dilemma of much of the Western church. It is possible to study the Scriptures in such a way that its central emphasis upon formation for mission is missed. It is possible to hear the gospel primarily in terms of what God’s grace does for me, or for you. It is possible to take the Bible seriously, persuaded that it is primarily about one’s personal salvation. It is possible to preach the Bible in such a way that the needs of persons are met but the formation of the whole community for its witness in the world is not emphasized. It is, in short, possible to be Bible-centered and not wholeheartedly missional.
Dallas Willard has said that our churches are full of converts who do not intend to become disciples. Another way to put it would be this: Our churches are full of people who are there to receive the benefits of grace without knowing that they are receiving such blessings “in order to be a blessing.”
