In today's Gospel reading (Mk 4:35-41), the apostles ask a question in wonder and fear. "Who then is this whom even wind and sea obey?" They really don't realize that God is in their midst in a very direct, personal way. They are beginning to see it, and I am sure it frightens them.
On another level, *we* are being asked the same question. We know from Mark's account that Jesus calmed the sea - commanded the "proud waves be stilled". We are asked, then, "who is this?"
In the first reading (Jb 38:1, 8-11), God tells Job who can still the waves and bar the sea. He can - God alone. By considering God's words to Job, we can answer the question posed by the apostles in the Gospel of Mark. Who is this Jesus that can command the sea? He must be God Himself in flesh.
