keep this miracle a secret

Ever wonder why Jesus told people to keep his miracles a secret? Seems like a strange thing to do and usually no explanation is given. But there is one instance in Matt. 12 where we are told why Jesus did things this way: 

But Jesus knew what they were planning. So he left that area, and many people followed him. He healed all the sick among them, but he warned them not to reveal who he was. This fulfilled the prophecy of Isaiah concerning him: (Matthew 12:15-17 NLT)

 Jesus ministered like this because it was in keeping with what Isaiah prophesied about him. In the Isaiah passage (which Matthew also quotes), we see that this approach pleases the Father and has certain qualities:

Look at my servant, whom I strengthen. He is my chosen one, who pleases me. I have put my Spirit upon him. He will bring justice to the nations. He will not shout or raise his voice in publicHe will not crush the weakest reed or put out a flickering candle. He will bring justice to all who have been wronged. He will not falter or lose heart until justice prevails throughout the earth. Even distant lands beyond the sea will wait for his instruction. (Isaiah 42:1-4 NLT)

Ministry that is dependent on the Holy Spirit does not draw attention to itself, is completely gentle, and yet so strong it never gives up. This is what pleases God. This is what Jesus did. This is what Jesus calls his followers to do (and how to do it).
