Sound travels further over water. When the crowd gathers around him, Jesus gets in the boat to make it easier for everyone to hear his teaching.
How blessed are we that our Lord is eager to speak to us and make sure we hear his voice. Today I will take time to listen.
On that day, Jesus went out of the house and sat down by the sea. Such large crowds gathered around him that he got into a boat and sat down, and the whole crowd stood along the shore. Matthew 13:1-2
