Now that I have your attention :) have a look at Matthew 9:27-31. Two blind mind follow Jesus, begging him to heal them. After doing so in private,
"Jesus spoke sternly, 'Don't tell this to anyone!' But they left and spread the news about Jesus all over that part of the country.
However, Jesus has already become well-known in his travels, and he has performed a number of public miracles:
"Jesus went all over Galilee, teaching in the synagogues, preaching the Good News about the Kingdom, and healing people who had all kinds of disease and sickness. The news about him spread through the whole country of Syria, so that people brought him all those who were sick...and Jesus healed them all."
When Jesus came down from the hill, large crowds followed him. Then a man suffering from a dreaded skin disease came to him, knelt down before him, and said, 'Sir, if you want to, you can make me clean.'...At once the man was healed of his disease."
It's also interesting that, unlike in the previous miracles, Jesus questions the faith of the blind men.
" 'Have mercy on us, Son of David'! they shouted. When Jesus had gone indoors, the two blind men came to him, and he asked them, 'Do you believe that I can heal you?' 'Yes, sir!' they answered."
My question is, given the previous events, 1) why do you think Jesus insisted that the miracle be kept a secret, and 2) why did he question their expressed faith?
