“Our Scriptures, confessions, and creeds are all very public, out in the open. Anyone can easily learn what it is supposed to mean to be a Christian. Our Bible is open to public examination; so is the church’s life. That is our problem. People can read what our Scriptures say, and they can see how Christians live. The gulf between the two has created an enormous credibility gap.” – Jim Wallis
