From this week's Advent Devotional (found here):

There are people in our neighborhoods, in our church, and in our community who need to know of God's love. Select someone to visit today. Visit by phone or in person. Go as a family or by yourself. It doesn't necessarily have to be a visit to a home. Maybe there is someone who waits on you at the grocery store. Stop by today and talk with that person. Tell the person you visit how you are reminded of God’s love because of what that person has said or done.
