This picture makes me think of verses such as Psalm 18:2.
"The LORD is my rock and my fortress and my deliverer,
my God, my rock, in whom I take refuge,
my shield, and the horn of my salvation, my stronghold."
Mightier than the thunders of many waters,
mightier than the waves of the sea,
the LORD on high is mighty!
Then, if we turn the picture a different way, we might think of....
"Everyone then who hears these words of mine and does them will be like a wise man who built his house on the rock. And the rain fell, and the floods came, and the winds blew and beat on that house, but it did not fall, because it had been founded on the rock. And everyone who hears these words of mine and does not do them will be like a foolish man who built his house on the sand. And the rain fell, and the floods came, and the winds blew and beat against that house, and it fell, and great was the fall of it." (Matthew 7:24-27)
