How does one teach with authority?

The people were amazed at his teaching, because he taught them as one who had authority, not as the teachers of the law.  Mark 1:22

            Teaching with authority means that Jesus provided insight they never heard before.  He taught with knowledge, never fumbling, but always backing up his teaching with scripture.  It also hints that Jesus didn’t turn to clichés and quotes from previous rabbis because he had his own way of understanding it.  In addition, he spoke telling people, confidently, what they needed to do like a boss or one in authority (but with compassion).
