Cross-Selling

I just finished reading Your Marketing Sucks and wanted to convey something stuck out to me from one of the final chapters.  In the chapter entitled "Pick the Low Hanging Fruit" we encounter the term "cross-selling."  Cross-selling basically means that you try and sell another product to an existing customer.  This idea struck me because I think that is what we can do inside the church.  We cross sell the Gospel and our events to existing customers.  We have to go out and find people who don’t already have the Gospel.  Stop cross-selling and start opening lines of communication with people who aren’t within the church.
