Lord make me humble....
I write this posting as humbly as I can, but realise it may sound arrogant. It really is what I think and I believe. I feel have good reasons to feel the way I do, having had many conversations with many dear brothers/sisters. And I want my motive to be gospel glory to God.
That said....Every so often, I am bewildered as to why more people are not doing church properly! Deliberately there are no names in this posting, though I could mention many. I think you know who you are. You are my dear brothers and sisters who are sold on the gospel principles of mission through community, even rave about them, but refuse to change.
It is bizarre. Good gospel people who want their lives and ministry to be bible-centred through and through, but 'cannot', for various reasons, make the paradigm shift. I put 'cannot' in quotes. I am convinced it is sheer disobedience in some. Fear of man. Fear of change. Fear of discomfort. An idolising of a certain form of ministry. A basic unwillingness to let the gospel and nothing else drive their ministry.

Before our difficult upheaval to Sheffield, I remember talking with several ministers at a conference. Bible men. Faithful men. It shocked me as they admitted, that they were convinced of the principles of TCH. Biblically convinced. But, it would not be 'practical' to do it. It would 'cost too much' (ie losing kudos and reputation among colleagues). They had been too long doing it the old way that they only knew how to do it that way. 'We'll leave the radical stuff to the mavericks and extremists'. Or what I often hear, 'we'll tinker with what we have and make it a little better by bolting on gospel principles to our longstanding traditions, without the paradigm shift'. Or even, 'let's see if it works first before committing ourselves'.
That's terrible! 'Let's see if the gospel works then we'll commit, if we deem it successful'!
Where is the willingness to put gospel first whatever the cost? Do you think it is easy for us? Do we just like being off the wall and breaking with convention? No!
It's a gospel decision that has led us here to do what we're doing. I too was convinced biblically of the principles of gospel centred church planting, so I moved. One of the hardest things we've ever done. But to not give myself to the gospel was disobedience. It has cost us reputation. It has cost us the loss of significant financial support. But so what? I have never been more convinced of anything.
I close with a quote from the intro to a very helpful book you must read: The Gospel-centred Church.

When the Bible talks about the church it uses a variety of exciting and
dynamic images. We are the Bride yearning for our wedding day and
beautifying ourselves for it. We are a thriving, bustling city of people
drawn from every race and walk of life. We are the active body, directed
and controlled by Jesus Christ our head. We are the pilgrim people of God,
being led across the desert to the promised land. We are the army of the
Lord, wielding the sword of the Spirit, which is the Word of God. We are
the light on a hill, shining the hope of salvation to a lost world.
But ask the impartial observer to come up with a metaphor for what he
observes, and we get a very diffent reality: we are fossils, hidden away in
our museum piece buildings. We are tortoises who move so slowly
because we are inherently conservative and resistant to change. We are a
spluttering candle that gives no light to anyone on anything. We are a
cosy club, dedicated to the preservation of our curious rituals, outdated
music, archaic buildings and stubborn and unreactive structures.
To greater or lesser degrees, we have fallen into accepting and perpetuating our own traditions and failed to remain dynamic, active and open to change for the Gospel’s sake. The result has been painfully obvious. A great decline in the those involved in church, and many congregations that have, for whatever reason, simply lost the plot.

In recent years, we have been bombarded with prescriptions for shaking
our churches out of this deadly spiral. We have been encouraged to adopt
new styles of worship, new cell or small-group structures, alternative
leadership patterns or to adopt the principles of business re-engineering.
While there is value in many of these approaches and techniques, they
are ultimately doomed to failure if they do not spring from the nature of
the Gospel truths which we are both saved by and serve.
