Mike Brantley has done another great post where he dialogues with his brother in law Gavin Knight (a successful church leader of a mainline Christian Congregation.) He was asked by gavin on how you define success in the Missional Church paradigm. Mike Brantley replied:
Measuring success: Just had a conversation this past week of how we are doing that. Souls in heaven is the ultimate isn’t it?! What we (our community and not able to speak for anyone else) is using a pathway: not interested, potential contact, contact, participating, journeying, embracing the Gospel, grounding, serving, growing, reproducing, catalyst... This left to right scale is a method we use to measure where we are with EVERY contact... From a Rona (whom you know) to Justin (latest newsletter) they are on there; what we are doing is discussed, what next, managing the conversational journey with them, etc. SO there is a measure of success as we move them along.
Anyway, there are many great things that are said in this post, especially some really practical thoughts on Missiology (the study of how to do mission in the culture we live.) You can find the full post here.
