An adhesive is any substance that, when applied to the surfaces of materials, binds the surfaces together and resists separation. Larry Osborne is lead pastor of North Coast Church in California. His thesis in Sticky Church is simple: churches often spent a lot of effort trying to attract people to attend, but not enough trying to retain them. As he puts it: ‘If the back door of a church is left wider open, it doesn’t matter how many people are coaxed to come in the front door … Yet most churches give the back door scant attention.’ Invitation is a key to binding the visitor to the group of people we call church. Invite someone today to take a closer look at Christ and his church and if they say yes invite them again. By inviting them a second time and on subsequent occasions we start the process of making sure they know we want them to stay.
