My boys had the opportunity to train in martial arts at a young age. It was hard work, but they loved it. Their heroes, I mean instructors, taught them by example. If the instructor expected them to do a complex combination, then he or she had modeled it first. If there were questions, he or she broke down the combination and performed it in slow motion. My boys were won over immediately.
Two things happened at about the same time. Their favorite instructors left the school to pursue other endeavors such as military, first responder, and full-time mom. There was a shift in the atmosphere. Those remaining had reasons for staying and no reasons for going. My boys were strongly invited to become teachers to fill the gap in the roster. They felt incredibly blessed to be chosen to fill the shoes of those who had gone before.
"The harvest is abundant, but the laborers are few. Therefore, ask the Lord of the Harvest to send forth laborers for His harvest. Go on your way. Behold, I am sending you out like lambs among wolves..." Luke10: 2-3
