The disciples really missed the boat. Jesus wanted them to have a waterproof faith, an unquenchable trust in him. He wanted them to learn to ride the waves. But they were overcome by their fear. Their fear is contrasted with faith.
Faith drives out fear.
The Bible teaches that we have not been given a spirit of fear. When we trust God, we have no reason to fear. For we know that as long as we are in God's hands we are safe. That is faith. This story isn t about what Jesus did.
