There is a great interview with Sri Lankan lay theologian, Vinoth Ramachandra, the author of the excellent book, Subverting Global Myths. Here is a quote from the interview in which Ramachandra talks a bit about what he thinks Christian faithfulness means (or should mean) in our world:

My fundamental conviction remains the absolute lordship of the crucified and risen Jesus Christ over every area of life. My second conviction is that we cannot bear credible witness to this truth without entering, imaginatively, into the pain of those who suffer the consequences of the worship of lords other than Jesus Christ. Such false lords—idols, ideologies—need to be unmasked in every age. I try to use my speaking and writing gifts to do that, but I find myself coveting other gifts—music, novel writing, filmmaking—which may be more effective in this present age. I have discovered that it is by embracing the suffering of others—in my case, remaining in a war-torn, poverty-stricken nation rather than seeking security in the rich West—that one is given insights and sensitivities that may elude others. Another conviction is that faithfulness to Christ requires constant openness to others, even our fiercest anti-Christian critics, to see how our own faith and lifestyle may themselves be redolent with idolatry. The biggest objections to Christians and Christianity are ethical, not intellectual. I have little time for the kind of apologetics that is divorced from ethics and political life.

Some stuff we should all ponder there, I think.
