"do you not care that we are perishing?"

We read this story for our family worship Sunday morning:

And leaving the crowd behind, they took him with them in the boat. Other boats were with him. A great windstorm arose, and the waves beat into the boat, so that the boat was already being swamped.

But he was in the stern, asleep on the cushion; and they woke him up and said to him, "Teacher, do you not care that we are perishing?"

He woke up and rebuked the wind, and said to the sea, "Peace! Be still!"

Then the wind ceased, and there was a dead calm. He said to them, "Why are you afraid? Have you still no faith?"

And they were filled with great awe and said to one another, "Who then is this, that even the wind and the sea obey him?" (Mk 4.36-41)

And then we sang this:

My life flows on in endless song;
above earth’s lamentation,
I catch the sweet, though far off hymn
that hails a new creation.

No storm can shake my inmost calm
while to that Rock I’m clinging.
Since Christ is Lord of heaven and earth,
how can I keep from singing?

Through all the tumult and the strife,
I hear that music ringing.
It finds an echo in my soul.
How can I keep from singing?

What though my joys and comforts die?
I know my Savior liveth.
What though the darkness gather round?
Songs in the night he giveth.

No storm can shake my inmost calm
while to that Rock I’m clinging.
Since Christ is Lord of heaven and earth,
how can I keep from singing?
