They say the definition of impatience is standing in front of a microwave oven screaming at it to hurry up!
I live in a semi-tropical country. That means that by all comparisons, things grow fast. In March I planted some trees from tiny little seeds around our parking area at our offices. Now these trees are over 3 meters tall already. Pretty fast, actually.
But these trees are still not big enough to provide shade for my vehicle parked there. When I look at them I think, "Hurry up! Grow taller. Grow bigger. And do it now!" I try to think of what fertilizer I can put on them to make them grow faster. I am being impatient.
The truth is, good things take time to grow. While I may wish for success overnight, I can't expect to plant a seed one day and get a tree the following day. It just takes time. Especially for things that grow.
You see, I could have constructed a shade roof for our parking area. It would have been finished in less than a week and our vehciles would have been basking in shade for the past six months. But that shade roof would never grow. In fact, without a lot of maintenance it would probably be unusable in a couple years, depending on the materials I used.
If I wait one more year my trees will provide better and cooler (as in temperature) shade than any roof I could build. And they will continue to grow providing shade for decades to come.
That which is built can be big fast; that which is grown takes time.
So it is with disciples and church planting. I could build a church. It is growth by addition. But I'd rather plant a seed by making a disciple and watch, over time, a church growth movement multiply far beyond my own influence.
