From Don Whitney:
Many of us struggle to make conversation at Christmas gatherings, whether church events, work-related parties, neighborhood drop-ins, or annual family occasions. Sometimes our difficulty lies in having to chat with people we rarely see or have never met. At other times we simply don’t know what to say to those with whom we feel little in common. Moreover, as Christians we want to take advantage of the special opportunities provided by the Christmas season to share our faith, but are often unsure how to begin. Here’s a list of questions designed not only to kindle a conversation in almost any Christmas situation, but also to take the dialogue gradually to a deeper level. Use them in a private conversation or as a group exercise, with believers or unbelievers, with strangers or with family.
You can find the questions here.
