I get asked all the time what is a good Christian business idea. Most people are hung up on the thought that the only good Christian business will be a bookstore or something similar. The product you sell isn’t near as important as the way you operate the enterprise. A person can run a Christian bookstore and rip people off as easily as any other type of store. The key is how you run the business not what it sells.
Are you honest and do you give fair value to your customers? When you are involved in commerce you are basically doing and exchange. Neither side should come out on the short end of the stick in these situations. Instead, both sides should feel good about the value they obtained and the value they provided.
