We wanted to get secular people to think about spiritual things. The people involved in the current ad campaigns seem to have the same motivation. If we are going to advertise for God, either publicly or privately, there are a few things to keep in mind. The first is to speak in a language people outside the church actually can understand. This is why the new Bible ads are having so much success.
People judge books by their covers, so the way a Bible looks is important.
The billboards work for the same reason. Their short, simple statements are easy enough to communicate with the average commuter. When we advertise for God, the way we say what we say is important. But what we say is even more important. We do not use deception, nor do we distort the word of God.
