Here’s an interesting example of how miracle power can work. Apparently, just touching Jesus’ cloak may have been enough in some cases. Jesus said after his cloak was touched that power went out from him. It seems like he wasn’t even sure who touched him, but that didn’t stop her faith from healing her.
Luke 8
43And a woman was there who had been subject to bleeding for twelve years, but no one could heal her.
44She came up behind him and touched the edge of his cloak, and immediately her bleeding stopped.
45“Who touched me?” Jesus asked.
When they all denied it, Peter said, “Master, the people are crowding and pressing against you.”
46But Jesus said, “Someone touched me; I know that power has gone out from me.”
47Then the woman, seeing that she could not go unnoticed, came trembling and fell at his feet. In the presence of all the people, she told why she had touched him and how she had been instantly healed.
48Then he said to her, “Daughter, your faith has healed you. Go in peace.”
