Respect does not exists to the degree that it once had 50, 25, or even 10 years ago. How about respect in your life? You probably "honor your father and mother," a lot of the time, but what about other adults? God calls us to respect them just as much. Teachers, Pastors, adults in the church and in public, friends of your parents...all of these people. Especially people who are your leaders. The amount of respect you give to all of these people represents the amount of respect you really have for your parents, and most of all, God. If you have this respect for God, you will show it to all people, because that's what He asked, and that's what your parents ask. You parents don't just want you to respect them, they want you to respect all adults. That's what God wants as well. This respect also needs to be shown to your friends and peers, and yes, maybe even to those upper classmen, so long as they aren't abusing you. You should strive to have a high level of respect for all.
