“Jesus did not let him, but said, ‘Go home to your family and tell them how much the Lord has done for you, and how he has had mercy on you’”.

Mk 5:19 NIV 

“In the heart of New York City is a dry cleaning establishment my wife, Gail, frequents on almost a weekly basis. I’ve heard her talk about it several times. ‘The first time I went in I knew that there was something different about the place’, Gail usually tells friends. ‘In the city you get used to being treated as if you’re nothing in a lot of businesses. But then you come into this store, and you’re greeted as if they’d been waiting for you all day long. I almost think I want to get something dirty so that I can have a reason to stop in there. They always have a cheerful word, despite the fact that the cleaning machinery makes the store unbearably hot and humid. By the third time I stopped in, the men who run the cleaners knew my name. They always have my cleaning ready, and the quality of the work is excellent. One day when I was there (says Gail) I said to Larry, who works the counter, ‘You really make it a treat to come here. What’s the secret about your upbeat mood?’ He surprised me when he said, ‘I’m a Christian, and I figure that’s how Christians are supposed to treat customers’” (G.MacDonald, Forging a Real World Faith, p259).
Jesus refused to let the man follow him. Instead he sent him back home to tell the people there. He also wants witnesses in dry cleaning shops, engineering workshops, army barrack rooms, police stations and hospitals. 
Where does he want you? 

Lord, help me to bring glory to you where I am.
