“Make disciples” is about making “followers” or “apprentices” of Jesus. His “Great Commission” involves “teaching them” (knowing) “to obey/observe/put into practice” (doing) all that He taught them. Not just “teaching them,” but “teaching them to obey.”
Knowing and doing.
You have to know it before you can do it, but if you know it and don’t do it, …you never really knew it the way it was meant to be known.
You might want to read that last sentence again.
Know, go and do.
