When you are reading through blogs, they are often people who are planting churches or starting new type of works. To be involved in transitioning a church is a much harder calling, in my opinion. It is harder because it involves a lot more emotional and relational pain. Planting a church or doing a new work involved other types of pain, I imagine. Like financial pain and having to be bivocational. However I am no expert on planting churches, so I would be interested to hear what sort of pain growing a new church involves.
As to transitioning a church, Rick Warren nails it in this article.

He says,
"For a church to turn around it may take many, many minute degrees of change and a long time to make a complete turn around. I personally believe you have to be called to a church like that.
People ask, "Is it easier to start new churches, or is it easier to take existing churches and turn them around?" My answer is this: "It's always easier to have babies than to raise the dead." However, God is in the business of raising the dead! He's a pro at resurrections, but it just might take some time. "

He states that it takes as long to turn a church around, as it has been plateud for. GREAT! That means I am here for about 38 years.
We have seen Bedford turn around in about 11 years, not completely, but we are a whole lot more healthy now than when I first came here, and it has come with a lot of pain.
