American culture is growing increasingly hostile to biblical Christianity. However, it seems that whenever Christians call attention to this hostility in one of its various manifestations, other believers are quick to defend the world against the church.
I'm reminded of a children's movie that came out a few years ago. The film was clearly pushing a politically correct, anti-Christian agenda. Soon after, I read an article by a Christian leader praising said film.
Other examples abound. Christian parents excuse enrolling their children in public schools by claiming that the children (who may not even be converted) are missionaries. No. They're not. They're just kids, and you're allowing them to be indoctrinated into a worldview that is diametrically opposed to Christian orthodoxy. Evangelicals flock to see the latest biblical film (Noah, Exodus, etc.), and, regardless of how terribly anti-Christian said film is, they defend it on the grounds that it provides an evangelistic opportunity.
We don't need to defend the sins of unbelievers on the grounds that they provide us with such a wonderful opportunity to share the gospel. That is a bit like saying, contrary to the Apostle Paul, that one ought
to continue in sin so that grace may abound (Romans 6:1). Yes, God uses bad things to bring about good (Romans 8:28), but that's His job. We can be confident that God is using the sins of the world for the good of the church without minimizing or excusing those sins. Sin is still sin and ought to be condemned as such.
