Thoughts on welcoming newcomers at church

• Be warm, friendly and interested. 
• Find out what brought them to church that day. How did they hear about our church? Do they usually go to church?
• Show an interest in the person. Find out their story: where are they from? Where did they grow up? Do they live locally? Are they a Christian (if so, how did they become one?)? If not, what is their understanding of the Christian faith (probe to see interest levels and share the gospel if appropriate)?
• What does their daily life look like?
• What are their key relationships? Married? Single? Family?
• What are they interested in? What are they passionate about?
• If they're a Christian, and they're looking for a church to join, tell them about small groups and what usually happens at church. 
• Invite them to join you for morning tea, supper, dinner etc etc after church. The regulars know that supper is in the church hall after the service, but newcomers don't know anything: that there even is a church hall, let alone where it is, and that supper is on.
• Introduce them to other people at church, so they can start getting to know people and building relationships. It also takes the pressure off you for maintaining a conversation with a stranger. Also means that if they come back, other people will be around to say hello if you're not there.
• Include them in conversations, and when in a group conversation, be deliberate in making eye contact, so they know you are aware of them, that you're interested in them being a part of your group. Find a way to include them in the conversation.
• Find a point of commonality.
• Talk less, listen more.
• Be aware of what it's like to be new and a stranger. Think how you would feel and what would make you feel as if people wanted you there and wanted you to return.
