Another simple way of inviting someone is to let them evaluate your church as an outsider and give you feedback on its welcome level. Is your church really friendly to unbelievers or those who are not members of your church? These people are coming to your church for a purpose and their feedback will greatly help to improve the friendly level. In Appendix B, you will see the form you can print and give to them as secret shoppers.

Invite people to your church as secret shoppers and their feedback will greatly help streamline your church to be better especially in terms of how friendly the congregation is
