Luke 8:23
As they sailed he fell asleep. A squall came down on the lake, so that the boat was being swamped, and they were in great danger — Jesus asleep in a life-threatening storm is the same as Mark 4:38 — the one who knows the Father's sovereignty can rest in the storm that terrifies others. A squall (lailaps, a violent whirlwind storm) came down: the topography of the Sea of Galilee produces sudden severe storms. They were in great danger communicates the reality of the threat — experienced sailors recognize a life-threatening situation.
