In practice it undermines the transformation of faith. 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.

What has happened to create this doubt is that a problem (such as a deep conflict or a bad experience) has been allowed to usurp God's place and become the controlling principle of life. Instead of viewing the problem from the vantage point of faith, the doubter views faith from the vantage point of the problem. Instead of faith sizing up the problem, the situation ends with the problem scaling down faith. The world of faith is upside down, and in the topsy-turvy reality of doubt, a problem has become god and God has become a problem.

Calling means that everyone, everywhere, and in everything fulfills his or her (secondary) callings in response to God's (primary) calling.

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.

In working out our callings, we are to perform for one audience, the audience of One.

Calling is not only a matter of being and doing what we are but also of becoming what we are not yet but are called by God to be.

The story of Christian reformation, revival, and renaissance underscores that the darkest hour is often just before the dawn, so we should always be people of hope and prayer, not gloom and defeatism. God the Holy Spirit can turn the situation around in five minutes.
