Two quotes from John Stott's book The Living Church: Convictions of a Lifelong Pastor that I found at Thabiti Anyabwile's Pure Church blog:
First, I am assuming that we are all committed to the church. We are not only Christian people; we are also church people. We are not only committed to Christ, we are also committed to the body of Christ. At least I hope so. I trust that none of my readers is that grotesque anomaly, an unchurched Christian. The New Testament knows nothing of such a person. For the church lies at the very centre of the eternal purpose of God. It is not a divine afterthought. It is not an accident of history. On the contrary, the church is God's new community. For his purpose, conceived in a past eternity, being worked out in history, and to be perfected in a future eternity, is not just to save isolated individuals and so perpetuate our loneliness, but rather to build his church, that is, to call out of the world a people for his own glory. ... So then, the reason we are committed to the church is that God is so committed.
The Lord did two things together. He 'added to their number... those who were being saved.' He didn't add them to the church without saving them, and he didn't save them without adding them to the church. Salvation and church membership went together; they still do.
Read Thabit's commentary here and don't forget our membership orientation on March 8.
