Many people were touching Jesus as he passed through the crowd. They touched him as he was another person in the crowd.
One person touched Him as if He were God.
This He felt. Faith drew power from Him. This faith is that which knows God is all good, all powerful, all loving. She entered Christ.
When He came to the dead girls house all He asked for was `only believe`. He was asking of them the very act the woman had done just before. Those who ridiculed were `put outside`.
So many powerful images. `lived in the tombs`, `no clothes`, `pigs`...
For me this event is saying that these demons that divide us into `legion` are much more suited to dwell in pigs , and even then, they will destroy. This also showed those who were present that there was in fact a foreign presence in the man that drove the pigs to rush down the banks.
