Soul Renovatus

As I have journeyed through seminary, I have discovered this topic over and over again, yet find a variety of answers to the question, "What is a successful ministry?" I have contemplated undergoing a project to find out the answer. Is there actually a workable model we can use, or at least translate? What are the assumptions behind doing such a project?

There are many questions, but I've been dying to get to the bottom of it. So many variables are involved in answering the question, including the influence of consumerism. I feel compelled because many of my friends and colleagues over the years have been burnt by this question (including myself), and I'm curious on even if there is a workable answer or tool.

I know some have written books on this. I'm not sure if my contribution could be valuable or not. What do you think?

Or even more, what are your thoughts on the subject? What are some books, articles, or thoughts that have been helpful?

I am dreaming on how I can continue to make this a reality, which I foresee involves a lot of writing and research. We will see where it goes.
