If Jesus Christ is the head of the church and hence the source and goal of its entire life, true growth is only possible in obedience to Him. Conversely, if the church becomes detached from Jesus Christ and His Word, it cannot grow however active and successful it may seem to be.

When Christians concentrate their time and energy on their own separate spheres and their own institutions-whether all-absorbing megachurches, Christian yellow-page businesses, or womb-to-tomb Christian cultural ghettoes-they lose the outward thrusting, transforming power that is at the heart of the gospel. Instead of being 'salt' and 'light' -images of a permeating and penetrating action-Christians and Christian institutions become soft and vulnerable to corruption from within.
