I wonder what Jesus saw when he looked at this man. As soon as Jesus gets out of the boat this man comes out of the tombs to meet him. Did Jesus know that he too would one day be spending time in a tomb? Perhaps he also knew that, like the demon possessed man, no one could bind him. Chains could not hold the demoniac, hell couldn’t hold Jesus. The man knew who Jesus was instantly. It was as if all the evil in the world, bound up in this one man, knew the power of “Jesus, Son of the Most High God” to put an end to the suffering. As a fellow chain-breaker, Jesus knew what freedom would mean for this man. The man (or rather the demons inside) did not want Jesus to send them away, but Jesus – perhaps seeing in the man his own after death experiences, sent them away, leaving the formerly demon-possed man in his right mind. Later something interesting happens. Everyone around wanted Jesus to leave and the man, now without demons wanted to go with him. Throughout the entire book of Mark, Jesus is commanding people not to tell about their healing. Over and over again, he commands them to keep quiet. Here, but not only here, Jesus commands him to go and tell. The only other place in the entire book that Jesus commands someone to go and tell is after his own resurrection.
When tombs become empty, then people are told to go.
