Matthew faithfully records how Jesus affected people. When they knew he was around, they knew he would heal the sick. They knew that the power of the Holy Spirit was in him. All they needed was to touch him to tap into that power.
I need to understand the power of Jesus, my Master. Do I “get it”? Do I really understand it?
All I need to do is to touch him, connect with him. The power of God is already there. It is just waiting for me to reach out.
On return, they beached the boat at Gennesaret. When the people got wind that he was back, they sent out word through the neighborhood and rounded up all the sick, who asked for permission to touch the edge of his coat. And whoever touched him was healed.
