The first one (Matthew 14:1-12) involved Jesus having to hear the news of John the Baptist being beheaded - it was John's discples who brought the tragic news to Jesus.
In trying to get away from the crowds in order to pray and process this news, Jesus is then swamped by 5000 people all needing help (Matthew 14:13-21). Jesus then feeds them with the 5 loaves and 2 fish, reminding us that God supplies all our needs - physical and spiritual.
The third incident involves the disciples trapped in their boat in the midst of a huge storm. Jesus comes to them in their trouble, fear and doubt and he says these words:
"But Jesus immediately said to them: “Take courage! It is I. Don’t be afraid.” - Matthew 14:27
I can think of no better word for the present crisis in our world than these words of Christ.
It is I.
Don't be afraid.
Living in Grace
