Debate
Winning hearts is a lot more important than winning arguments. (Chris Tiegreen, devotional writer)
Organized debate was once a helpful means of achieving understanding. It allowed equal but limited time for debaters on both sides. Discussions were open and fair with careful listeners. Today, talking is too often interrupted with constant objections and little attention to logic or fairness. A civil exchange of ideas will more likely speak to the heart and result in better understanding.
Do everything without complaining and arguing (Philippians 2:14).
