In "God's Word for Today" Gordon Snider writes:

God has always called His people to give special attention to their relationships with their neighbors. A review of the nearly thirty times the word is used in the first five books of the Bible shows that any wrong is magnified if it is committed against a neighbor. In his attempt to avoid that added responsibility, the lawyer who questioned Jesus in Luke 10 asked, “Who is my neighbor?” Jesus' answer was the story of the Good Samaritan. Our age of electronic communication has greatly expanded our neighborhoods. Many people carry on meaningful relationships with people they have never seen. A starting place for today's lesson could easily be a repeat of the lawyer's question, “Who is my neighbor?” Once that question has been answered, the Christian is faced with the responsibility of that relationship. The texts for today's les-son help us to better understand that responsibility.
