Discipline in a Long Distance Race

I got this from fellow Scout Dad J Stirling, last night:

... at the end of the trip I had a brief Interaction with Taylor where I told him he needed to be helping with the clean up and he said "shut up" to me in response. I am not sure if he intended for me to hear it or not, but I did hear it.
I spoke with him about it, and let him know he wasn't permitted to speak to me or any other adult or any other scout like that because it was disrespectful. To that he responded "I know it was disrespectful - that's why said it to you."  At that point I just let him know that I would speak with his father about the issue and I walked away from him.
Another father on the trip spoke with Taylor about his response to me and instructed him to come apologize to me.  Taylor did so in a sincere manner and I accepted his apology. I let him know that we were out here to learn how to work with others and that required everybody to contribute to the effort and that the process also involved learning how to be respectful in the process. I also let him know that I wasn't angry with him. I think he was pretty emotional and tired at this point and I think some of that overflowed in his reactions with me.
 I am not upset about the matter as this is part of the learning process, but I did think it was important for you to know what happened. If you have any questions about this please let me know.

While I am so grateful for the obvious care and effort from Stirling, it is also remarkable that I just heard this preached from Pastor Lam yesterday, from Heb 12 (the Message):

4-11 In this all-out match against sin, others have suffered far worse than you, to say nothing of what Jesus went through—all that bloodshed! So don’t feel sorry for yourselves. Or have you forgotten how good parents treat children, and that God regards you as his children?My dear child, don’t shrug off God’s discipline,    but don’t be crushed by it either.It’s the child he loves that he disciplines;    the child he embraces, he also corrects.God is educating you; that’s why you must never drop out. He’s treating you as dear children. This trouble you’re in isn’t punishment; it’s training, the normal experience of children. Only irresponsible parents leave children to fend for themselves. Would you prefer an irresponsible God? We respect our own parents for training and not spoiling us, so why not embrace God’s training so we can truly live? While we were children, our parents did what seemed best to them. But God is doing what isbest for us, training us to live God’s holy best. At the time, discipline isn’t much fun. It always feels like it’s going against the grain. Later, of course, it pays off handsomely, for it’s the well-trained who find themselves mature in their relationship with God.12-13 So don’t sit around on your hands! No more dragging your feet! Clear the path for long-distance runners so no one will trip and fall, so no one will step in a hole and sprain an ankle. Help each other out. And run for it!
