"Teaching that stimulates the intellect without speaking to the spirit cannot nourish."
I believe this is not just a message for Sunday school teachers. I believe it is something we should be trying to apply in everything, including as parents and in working with the Scouts. I have come to see more and more that Scouting in the Church is meant to be about more than just camping and fun activities. Used well, it is an effective vessel for serving the gospel to boys and teaching them their priesthood responsibilities. Like the priesthood, the ideal Scouting program will merge temporal and spiritual in a seamless unit. (Notice I said "ideal." See former post about taking steps "line upon line.")
"Teaching that is nourishing to the soul uplifts others, builds their faith, and gives them confidence to meet life's challenges. It motivates them to forsake sin and to come to Christ, call on His name, obey His commandments, and abide in His love."
One of my training handouts I keep on hand is a checklist titled, "How do I rate as an effective leader?" While there is nothing wrong with the handout, I think this quote can give us a simpler and more useful yardstick to measure our effectiveness. Ask yourself, "Does my teaching accomplish these things? Am I building their faith, giving them the confidence to meet life's challenges and motivating them to forsake sin?" (Is is just me, or does that sound a lot like the Aims of Scouting with a gospel slant?)
However, in trying to accomplish this, especially with teenage boys, you might relate to this statement:
"Some people may not seem interested in hearing the principles of the gospel. You should prayerfully search for a way to teach them those principles anyway."
I think the key words here are "prayerfully search." Maybe sneaking some gospel teaching into a camp out or hike is one way to accomplish it. Remember, we can't always tell when they are listening or what they get out of something. I like the story from a mom about their family's struggle to have family scripture study:
"...we were often frustrated when one son complained and had to be coaxed out of bed. When he finally came, he would often put his head down on the table. Years later, while serving his mission, he wrote home in a letter: 'Thank you for teaching me the scriptures. I want you to know that all those times I acted like I was sleeping, I was really listening with my eyes closed.'"
Please remember to teach with a purpose, even if you need to let them "listen with their eyes closed" sometimes. Pray about your boys and let the Spirit guide you.
