One of the key places where sociology should be used is in analyzing 'the world' of our times, so that we can be more discerning. To resist the dangers of the world, you have to recognize the distortions and seductions of the world.

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.

This is also why it is wrong to treat God as a grand employment agency, a celestial executive searcher to find perfect fits for our perfect gifts. The truth is not that God is finding a place for our gifts but that God has created us and our gifts for a place of his choosing – and we will only be ourselves when we are finally there.

In other words, we are never freer than when we become most ourselves, most human, most just, most excellent, and the like.

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.

Idolatry is huge in the Bible, dominant in our personal lives, and irrelevant in our mistaken estimations

Followers of Jesus who count the cost and are willing to take up their crosses after him must have broad shoulders.
