The Great Commission is a commission to “teach all things” whatsoever Christ has commanded us. Those include why we eat and sleep, the proper view of government, the proper view and place of vehicles, the proper view of warfare, in short, everything that can be imagined. “The scripture is authoritative on everything which it speaks, and the Scripture speaks to everything.”
The Great Commission is a call to teach the gospel of Christ, which reforms the world. Thus, if, in your life, right now, that takes the form of “just” being respectful to your parents, then you are reforming the world. If you are just being kind to you brothers and sisters when they break something of yours or ask for your time, then you are reforming the world. If you are “just” spending your time to glorify God in whatever you are doing, even if it is “just” being a faithful son or daughter, then you are reforming the world.
Through His Strength We Will Conquer,
