It is a very instructive vignette in the life of Jesus and his disciples, recorded for us in Mark 6:45–52. Jesus has sent his disciples across the Sea of Galilee to Bethsaida. They have encountered an impossible headwind and angry seas. If you look at the time clues in the larger passage, you can see they have been rowing for about eight hours. They are in a situation that seems impossible, exhausting, frustrating, and potentially dangerous. They are far beyond their strength and ability.
