In Jewish culture, the sea is a representation of chaos and the origin of evil. So, when Jesus came walking on the sea to the disciples who were in great distress in the storm, it is a sign. It is a sign that leads us to life and informs our faith in Jesus. When we see Jesus walking on water on the rough sea in a dark and stormy night, it tells us that Jesus is Lord! When our life feels like a sinking ship and we are in a dark and stormy situation, we are not alone.
