Jesus then asks them if they have the faith to believe he can do this. Jesus tells them not to announce their healing to others, but they go and announce it all over the district. The lesson for us seems to be that we are never encourage those who are healed to announce this to the public. At the same time we recognize that there is nothing we can do to stop the news getting around. This person is possessed by a spirit that prevents him declaring his faith in words, or even asking friends to take him to Jesus.
Faith therefore seems to be effective in many different ways.
But as we have seen it is the direction of faith towards the power of a loving God that is important, not our specification of what we think a proper faith should be. As the work of teaching and healing proceeds, the needs multiply. The greater the harvest the more workers must be called in to help, and the way this is done is by prayer. Presumably in each case hearers will respond in faith in different kinds of way. As the crowds gathered around Him, the Messiah is touched by their need of care and shepherding.
