I was slightly critical earlier on this document, and everyone pretty much knows my personal understanding on tongues, etc. And, there are many assumptions and views underlying the document that I'd take issue about. That's all an academic argument and probably unfruitful since they haven't asked my opinion. But, I did re-read it and I want to point out some things that are positive about it --- although it requires a little different reading than the one intended by the authors, I'm sure.
1. "Spirit-filled believers make up the largest and fastest-growing segment of reformation Christianity in the world." Now, I don't know precisely where that comes from statistically, and I supposed I'd differ with them on the definition of a "Spirit-filled believer", but I am enamored with the notion of "large" and "fast-growing" "reformation Christianity".
I hope that, whatever they are in terms of pentecostalism (and, let them be as Pentecostal as the BDP encourages for all I care), these people who meet what the BDP committee is defining turn out to be a force for truly and literally turning the world upside down.
2. The acknowledgement of Western drift from following the Holy Spirit. Again, they probably intend something different than I think of when I read that statement, but it is a true one nonetheless. Reform by really following Christ would not only challenge but maybe even eviscerate Western values, and I say that as a life-long and presently ardent Western values kind of guy. Nothing about transformation is going to be nicey-nice to any of us or our preferences for the world. For me, Acts 2 is the chapter that opens a door on what this looks like, but it has nothing to do with the tongues part (vss. 42-47).
3. "Be filled" is not optional. For any believer. I don't know how these authors would treat someone like myself; maybe they think I'm not a believer at all since I don't see "being filled" in the sense they are advocating in this context of manifestations, etc. But, the truth is still there in the recognition that being Spirit-filled is no option for a believer. When I couple that with what they said about reformation and drift, I take away from it a really relevant advice to walk humbly with God and to do something affirmative to serve Him and others, to expand His kingdom. Even if they'd disagree with me on how I'm interpreting their statement.
