What is success?

I recently heard a church planting group in Georgia bragging because over 70% of their church plants are successful. So when I asked what they considered success, they said that if a church was still going after two years then they considered a success.

WHAT???????

I know many of these church plants firsthand and I consider very few of them a success. But what is success in a church plant? I am number driven but it can’t be all about numbers. I am life change driven but if a church isn’t growing is it seeing life change?

I don’t have the answers but I would love to hear your thoughts on what and when you consider a church plant a success?
