Oh yes. The Message. I forgot.
The church's primary "purpose" is to preach the word, in season and out. that's it. The rest of his so-called 'purposes' will come from that, because that's what the Word, rightly handled, does.
Focusing on polishing the cart will not put a horse in front of it.
I’m a little confused by your implication though that because he is seeking to ‘polish the cart’ he is not seeking to preach the Word.
Part of our responsibility as followers of Christ is ‘to live such good lives among the pagans that , though they accuse you (us) of doing wrong, they see your (our) good deeds and glorify God on the day He visits us.’(1Peter 2:12)
We are Christ’s ambassadors, and as such need to keep our cart ‘polished’... not so that we look good, but so that we represent our Father in a dignified manner. My cart may be simple, but I will keep it looking it’s best.
It would seem by the number of people that have come to Christ through Warren that he is preaching the Word adequately. The honor and glory though, belong to God and His Word, and not to Warren.
