Mark 6:46

And when he had taken leave of them, he departed into the mountain to pray.

To the mountain to pray ... A bold headland overlooks the grassy slope where these events occurred; and, as soon as the Lord had sent the Twelve to the other side and dispersed the multitude he had recourse at once to prayer. It was indeed an hour of crisis; never was the ministry of Jesus any more threatened than at that hour. It is from this that the surpassing importance of this miracle derives. John made it one of the only seven signs that he recorded, and none of the gospels left it out. Equally important was the accompanying wonder of our Lord's walking on the sea to go to the rescue of the storm-tossed apostles.
