I was really taken the other day with the story of Legion in Mk 5:1-20; especially with the conclusion of the story. Here is the man, delivered from his terrible affliction (perhaps 2000 demons!) and in his right mind. He says to Jesus, 'can I come with you?' In other words, can I join the 12, the team; and join the mission? Jesus' answer is no! You can join the team, but I have another task for you to do. Rather than come with me and my apostolic team, I want you to go back to your home and community and tell them what I have done for you.
This illustrates a lot about call for me. First, we don't call ourselves to a particular role or ministry; rather, Jesus assigns us our task. Second, some of us will be told not to go to another mission field, but told to go home and testify to the salvation we have experienced in Christ. Third, this tells us that essential to mission is the power of testimony; sharing what God has done for us. For this guy, it was an amazing deliverance from terrible suffering and bondage.
It is not clear whether the guy obeyed Jesus or not. We are not told where he is from. He goes to the Decapolis, a region including ten cities and he tells what Jesus has done. Perhaps this is his home, perhaps not; either way, I love this guy. He takes on 10 cities for Jesus! So it is a great story of obedience to Christ.
So we can take from this that we are all called to tell others about what the Lord has done for us. The question for us all is, where do you want us to do it Lord? There is only one way to find this out; sitting silently in the presence of the Lord and seeking his direction and then going for it.
