Drawing from Jesus's prayer in John 17, we discover that Christ's final petition before His arrest wasn't about doctrine, miracles, or even protection from persecution. Instead, He prayed for unity among His followers, connecting this unity directly to the world's ability to believe in Him. The message challenges us to examine how our preferences, from trivial matters like phone choices to weightier issues like worship styles and political views, can become sources of division that undermine our witness. We're reminded that Satan isn't concerned when we argue over secondary matters because our infighting accomplishes his goal without him lifting a finger. The sobering reality is that division functions as evangelism in reverse, canceling out even our best ministries, facilities, and theology. As we reflect on Galatians 5:15's warning that we can destroy each other through biting and devouring, we're called to ask ourselves a crucial question: Did our words, actions, and attitudes in the past year make our church more united or more divided? This isn't merely a church growth strategy but a matter of eternal significance, as Jesus Himself tied unity to the world knowing that the Father sent Him.
