What we see in the Great Commission is the mandate to make disciples (i.e. see people saved, baptized, and brought into the church where they can be taught to observe all things - beliefs, practices, ministries, etc.). If we have a mandate to teach, then the flip side must also be true. We have a mandate to learn. A disciple is a learner. And to learn we must have some discipline.
In Lk 2:46-47 Jesus was learning. He was doing it the old fashioned way, i.e. asking questions, reading the law, discussing, etc. If Jesus was determined to learn, then let's follow His example. Jesus didn't sit in a school of religious law, but He certainly leaned the Word of God. (John 7:15)
