As I have been making some tentative forays in evangelism here in So Cal it seems that two things have been particularly useful, joy and ceremony:
(1) Joyfulness. Real joyfulness is a definite calling card. Instead of telling people about how doctrinally sound you are or what you are against we are living out the genuine joy we feel. Talk is cheap and people want to see and feel what you claim as truth. Hey, how can we not? King Jesus is risen and reigning and he has brought us along for the ride. Its infectious but awkward for us scowling super-serious reformed types.
(2) Ceremony. We seem to have reached the end of the road with the rational church. Ockham's Razor has sheered away everything but the hollow shell of a building and drably dressed parishioners. We also try to worship drably in order to supposedly fulfill a mandate to worship in "spirit and in truth." Its really all in our heads. This has hit a block wall in the Post-Modern, Post-Christian world that is LA. It all made some sense when your audience had a Christian frame of reference but it all looks terribly arid and meaningless to a generation that was raised outside of Christianity or within drab evangelicalism.
So what do you do? Well, you could take the typical evangelical approach and spruce up some of the outward trappings or you could re-vamp into an earlier mode of thinking, contextualized of course. There's a reason why the church for 2000 years thought the faith, in its corporate expression, should be seen, felt and heard. Its not just a set of dry facts, its a kingdom advancing in all its splendor. I am finding it very easy to invite people to a church that is unapologetically liturgical and robust in its expression of the same.
So, how does this all work? I don't know yet but I will keep you posted. You see, its not a strategy but the way the church has always lived and worshiped. We, in the West, are the ones who got off track and its time to get back into the rhythm of God's glorious, ever maturing and expanding Kingdom.
