On Route 3 somewhere between Augusta to Belfast, you will find a bright, shiny red Mustang with two signs printed on the back. The first sign is the name of a driving academy and a telephone number. The second sign has three simple words: "DRIVE THIS MUSTANG!"
It is quite a contrast to the driving academies in most hometowns; their cars are nondescript, uninteresting vehicles, and if the academy put a sign on their cars that said, "DRIVE THIS CAR", everyone would laugh.
"The car represents the academy in two ways: The sign represents the academy in words, but also, the car itself is a representative of the academy. People who see the Mustang will know all the information they need to contact the academy, but it is the Mustang itself that is the real advertisement. People who see this car will say, "That is the academy I want to go to!"
In the same way, we should be the "advertisement" for Christianity both in our words, and in our lives. Our words tell others about Salvation which is to be found only in Christ. But our lives must be an advertisement for Christianity as well; when people look at our lives, they ought to say, "That's a life that's a cut above the rest, and if that's what Christianity is, I want that!"
Our words and deeds must go hand in hand. One without the other is pointless.
We are therefore Christ’s ambassadors, as though God were making his appeal through us. We implore you on Christ’s behalf: Be reconciled to God.
-2 Corinthians 5:20 (New International Version)
Dear Lord we pray that we would be the advertisement that you would have us to be. We pray that when those around us see us they will want to be a Christian also. In Jesus’ name, amen.
