What if the secret to a joy-filled life isn't found in accumulating more possessions, achievements, or even moral superiority, but in something radically counter-cultural? This message confronts us with a powerful visual metaphor: we are like cups full of holes, constantly trying to fill ourselves with things that promise happiness—technology, success, recognition, comfort—only to watch it all leak out. Jesus offers a different path in John 13-17, where He gives what might be called the 'internal Great Commission.' Right after washing His disciples' feet and sharing the Last Supper, Jesus commands them five times to love one another as He has loved them. This isn't merely a nice suggestion; it's the pathway to complete joy. The Greek word used suggests being filled to the brim, overflowing. Jesus Himself demonstrates this principle—Hebrews tells us that 'for the joy set before Him,' He endured the cross. His 'why'—His love for others—sustained Him through unimaginable suffering. When we make loving one another our central mission rather than self-focused pursuits, we tap into a sustaining joy that doesn't leak away. This doesn't mean life becomes easy or conflict-free, but it means we find fullness even amid difficulty. The challenge before us is clear: will we continue chasing the 'iPhone life' of convenience and self-centeredness, or will we embrace the cross-shaped life of sacrificial love that actually plugs the holes and fills us with lasting joy?
