“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.”

“There is no problem with the wider culture that you cannot see in the spades in the Christian Church. The rot is in us, and not simple out there. And Christians are making a great mistake by turning everything into culture wars. It's a much deeper crisis.”

“Christians simply haven't developed Christian tools of analysis to examine culture properly. Or rather, the tools the church once had have grown rusty or been mislaid. What often happens is that Christians wake up to some incident or issue and suddenly realize they need to analyze what's going on. Then, having no tools of their own, they lean across and borrow the tools nearest them.They don't realize that, in their haste, they are borrowing not an isolated tool but a whole philosophical toolbox laden with tools which have their own particular bias to every problem (a Trojan horse in the toolbox, if you like). The toolbox may be Freudian, Hindu or Marxist. Occasionally, the toolbox is right-wing; more often today it is liberal or left-wing (the former mainly in North America, the latter mainly in Europe). Rarely - and this is all that matters to us - is it consistently or coherently Christian.When Christians use tools for analysis (or bandy certain terms of description) which have non-Christian assumptions embedded within them, these tools (and terms) eventually act back on them like wearing someone else's glasses or walking in someone else's shoes. The tools shape the user. Their recent failure to think critically about culture has made Christians uniquely susceptible to this.”

“Calling resists privatization by insisting on the totality of faith. Calling resists politicization by demanding a tension with every human allegiance and association. Calling resists polarization by requiring an attitude toward, and action in, society that is inevitably transforming because it is constantly engaged. Grand Christian movements will rise and fall. Grand campaigns will be mounted and grand coalitions assembled. But all together such coordinated efforts will never match the influence of untold numbers of followers of Christ living out their callings faithfully across the vastness and complexity of modern society.”

“To come to faith on the basis of experience alone is unwise, though not so foolish as to reject faith altogether because of lack of experience ... the quality of a Christian's experience depends on the quality of his faith, just as the quality of his faith depends in turn on the quality of his understanding of God's truth.”

“To believe in God is to "let God be God." This is the chief business of faith. As we believe we are allowing God to be in our lives what He already is in Himself. In trusting God, we are living out our assumptions, putting into practice all that we say He is in theory so that who God is and what He has done can make the difference in every part of our lives.This means that the accuracy of our pictures of God is not tested by our orthodoxy or our testimonies but by the truths we count on in real life. It is demonstrated when the heat is on, the chips are down, and reality seems to be breathing down our necks. What we presuppose at such moments is our real picture of God, and this may be very different from what we profess to believe about God. (God in the Dark, ch. 4)”

“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.”
