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.

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.

Too often we forget that the great men of faith reached the heights they did only by going through the depths.

The question the doubter does not ask is whether faith was really useless or simply not used. What would you think of a boy who gave up learning to ride a bicycle, complaining that he hurt himself because his bicycle stopped moving so he had no choice but to fall off? If he wanted to sit comfortably while remaining stationary, he should not have chosen a bicycle but a chair. Similarly faith must be put to use, or it will become useless.

Christianity is the only religion whose God bears the scars of evil.

In our day it's worse to judge evil than to do evil.

Negative freedom is freedom from - freedom from oppression, whether it's a colonial power or addiction to alcohol oppressing you. You need to be freed from negative freedom. Positive freedom is freedom for, freedom to be. And that's what's routinely ignored today.
