One of my most favorite parts of that story is Christ's statement when he enters, "Peace be with you." How often, when we pass the peace at church, are we merely saying the words, without thinking about what they actually mean? Part of participating in the community is participating wholeheartedly. Don't just say the words - Mean them!
Think about what you are wishing for the other person - do you wish them peace? Then look them in the eye, and say so, with all your heart. Do you give hugs when you pass the peace? Have you ever thought that your hug might be the only physical contact another person gets all week? How special that is to that person - and it can be more special by meaning the words you're saying, by passing the peace of Christ, which passes all understanding, onto that person. You might surprise even yourself.
Watch the video here, and think about how God sees each of us as His children - maybe you'll recognize some of your own congregants' inner children here. Peace be with You!
