Quantity (i.e. attendance numbers) isn’t a bad thing, as long as the quality is good. But quantity is useless when the quality is bad. Who wants to eat a whole truckload of rotten apples? One good apple is more valuable.
In his letter to the Galatians the Apostle Paul gives us a list of the good fruits followers of Jesus should be looking for in their lives.
But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control. Against such things there is no law. Galatians 5:22-23
These are the indicators of success. Does a kid love better? Is he joyful? Does she exhibit self-control? If you think filling out your denominational reports is hard now, try measuring fruit in a report!
