We just need boredom. Our enemy is not interested in our utter rejection of the gospel if we are simply bored with our Christianity.
I ran across this great C.S. Lewis quote from The Screwtape Letters:
If you can once get him to the point of thinking that “all religion is all very well up to a point,” you can feel quite happy about his soul. A moderated religion is as good for us as no religion at all — and more amusing.
In our entertainment-driven church model (and I think again of that insane use of MMA for “evangelism”) it is a good reminder that Satan will use ANYTHING to take us out. If need be, he will simply make you BORED with Christianity. We will end up looking for the adrenaline rush instead of Christ.

To true here. It is ashame when I hear believers falling away from attending church saying in so many words “what’s in it for me?” Man what gives? Or put it this way, only go if so and so shows up (friends, etc), or if the Head pastor is preaching and not a fill in, or the worship music is exciting and not the boring hymnal songs. The list goes on. Whatever happened with the answer ‘Igo to Church because I want to hear the Gospel and be in the presence of the LORD’ We need to wake up.
