Yesterday I preached on 4 incredible stories from Mark 4:35-5:43 where Jesus calms the storm, heals the demoniac and the hemorrhaging woman, and raises Jairus' daughter from the dead. Afterwards, a member of my church asked me a great question: Why did Jesus tell the demon possessed man to go and tell others but told the ones who saw Jairus' daughter being raised to strictly tell no one? What a great question! Here's my response: The demon-possessed man was in a Gentile region where not many knew about Jesus or cared about the coming Messiah. In Mark 5:17, after Jesus had healed the man, they begged him to leave the area. Jesus left, but told the demoniac to go and tell what had happened to him since he would now be the only real witness in this region (Mark 5:19).
Now Jairus and his daughter lived in Galilee. This region would've been Jewish and therefore anticipating a coming Messiah and so Jesus wanted to keep this a secret because he didn't want to stir up a big crowd. The concern on Jesus' part was that people's attention would be distracted from what he really came to do, namely, the ministry of the word (Mark 1:38). His essential aim was to preach repentance and faith (the message of the kingdom) and then die on a cross. After he died and rose again, that's when he told his disciples to go and tell everyone who he was because that was the real message he came to bring as the Messiah.
