 When we think in terms of God's kingdom, we're thinking of his rule over his people and over his world. And when Mark introduces us to Jesus, he shows us that Jesus is the King and the Lord of creation. Hence the winds and the waves are subservient to him. That's why he's able to feed the 5,000 with the five loaves and the two fish. That's why he walks on the water. That's why the lame walk. That's why the blind see.
