They were filled with awe and asked...who then is this whom even wind and sea obey? This is not going to be the last time that the people are "amazed" at Jesus performing an out of the ordinary act (they had earlier labeled it a "new teaching"). In today's account, it is the disciples’ turn to be amazed. They get amazed at the harmony that has been displayed in Jesus' interaction with the forces of nature. Nature has "obeyed" Jesus.
Jesus came to right a wrong, a wrong that was perpetrated by our first parents and in which we continue to participate. The Genesis account of creation attributes the genesis of this wrong to disobedience (cf. Gen 3: 11b). Sadly, the disobedience of our first parents has since characterized the story of the created cosmos. The goodness that was exhibited when God created the universe has been annihilated and replaced by this disobedience. The harmony that existed at the beginning has been replaced by disorder and chaos. Creation is fighting itself and is tired (cf. Romans 8:19ff). Jesus' coming marked the beginning of the restoration of creation. By what he says and does, Jesus begins to restore the harmony that ought to exist (cf. Isaiah 11:6ff). In Jesus, the forces that have been at war begin to reconcile. Humanity and the rest of creation begin to come together and co-exist. The obedience that was lost is salvaged. Jesus is able to accomplish this because he himself is obedient to the Father (cf. John 14:31; Phil 2:6ff; Heb 5:8).
