There is not much evidence that we are putting out high quality disciples and the number of disciples sure isn't encouraging either. In a way we have sought joy to hard, but in a way, we have settled for two little. God would give us far more joy in Him than the meager offerings of this world could ever afford. We have not sought joy to much, we have settled for two little. The quality of life we create is more important than the number of lives we impact.
Numbers also matter.
The more important it is, the harder it is to measure. The bigger the scope, the easier it is to do so. For example, we can plot on a graph the fact that church attendance during my life time has been flat lined. I call this disobedience to what our Father told us to do. I write this lesson an encourage you to do this study for the purpose of fixing that problem.
