I make a mistake in this talk by saying in the OT God is spoken of as the only one who walks on water. However, I confused this miracle with the one of Jesus calming the sea.
In Psalm 89: 8,9 it says:
8 O LORD God Almighty, who is like you?
You are mighty, O LORD, and your faithfulness surrounds you.
9 You rule over the surging sea;
when its waves mount up, you still them.
So it is that miracle that Jesus does what is known to be an act of God
