Why Have a Statement of Purpose?

There was a helpful article that I came across from John Piper (written in 1983) on having a clear vision statement for the church: Why Have a Statement of Purpose? I am praying and planning to introduce and preach the vision I have for Cornerstone in Orange City this upcoming Sunday: "To glorify God by making disciples of Christ who will impact the world with His Gospel." I always appreciate any prayers for our church and I am continually humbled to serve Christ.
