Activity is good. Better is to produce. Still better is to reproduce.
Being busy is good. But mere activity could be just spinning your wheels in gravel. With production, you have something to show for your work.
But production is still inferior to “reproduction.” As Christians, we are ultimately called to reproduce Christians, not just “produce” things like manuals and seminars. Reproduction is the highest rung.
It’s also the hardest. With hard work and competent strategy, we get from activity to production. But only God can bring about reproduction. (Just ask couples afflicted with sterility!)
That’s why you shouldn’t just sprinkle prayer on top of your ministry like sugar. You should make it a main ingredient, like flour.
Remember, the disciples fished all night without catching anything. Then Jesus sent them out once more, and when they threw the nets, they were so full they were ripping!
