In "God's Word for Today" Gordon Snider writes:
As I write this lesson, the presidential race of 2016 is underway. In my lifetime, I have never seen the evangelical community so divided in a presidential election. Christians are “de-friending” other Christians on Facebook because the rhetoric is so strong. It just goes to show that it is difficult to fellowship with people who have strong feelings that differ from our own. Yet Paul, in today's lesson, calls for harmony in the face of disagreements. Disagreements will not vanish because the election is over. Serious conflicts still exist among believers over things like recreation, appearance, worship styles, and Sabbath observance, just to name a few. Paul was not calling us to compromise the truth, but he was calling the Church to live in harmony. Today's texts can give us clear direction about how to “shoot the rapids” of controversy while maintaining the unity of the Body of Christ. Perhaps no truth is more needed today than this one!
