I caught myself about 18 months ago while I was thinking about the work I'm involved. I suddenly realized that my perspective upon church planting was amazingly small and self-centred: I only thought in terms of 5-10 years. I was focused on what I achieved and what God did through me. Immediately I was struck by a strange thought. How about if I took a 100 year perspective?!! Let me commend the benefits....
If I think in terms of a 100 years everything changes. I might fail to really grow a church but the next guy will improve upon it, and then the guy after him. My failure does not mean the failure to impact the culture.... I'm just too short-sighted.Thus I can persevere in something because I don't have to 'win' now. Someone else down the line can 'win' by building on what seemed small and pathetic now. Ultimately, I can be patient with slow change in a community because taken over a 100 years it might be part of very Big Change. The real goal is not my life-span, my ministry and my success but God's glory - if I'm thinking 100 years ahead it gets my mind off myself to the true goal of history: Jesus Christ and His repute. How liberating this is! I recommend that every ministry have a 100 year plan.
