Modern culture is obsessed with the idea of wholeness. We like solutions because it breaks our heart to see others hurting -- especially those we love. I used to think that everything would be sorted out eventually. The right girl would fall for the right guy, the bad guys would get comeuppance, and the lonely girl would find hope in the midst of depression.
The sad side to the story is that the world isn't like that. That guy who was abused? He's going to suffer with that for the rest of his life. That girl with depression? She may come out, she may not. That lonely woman who has no one to spend Thanksgiving with this year? She might not spend it alone, but someone will.
It seems dark because our world is dark and we don't want to believe that. We can't believe that because we would lose hope. We need to tell ourselves that humanity is better than that; but it's not. The story of humanity is a sad one, impossible to cope with on its own; but humanity's story was never meant to be told alone.
With redemption, with God, there is hope. We want wholeness because we were made to be whole. That does not mean a perfect ending without pain, but it does mean that God has redeemed suffering. He has made our pain the path to save our souls. Without him, none of it makes sense; but with him, real life is beautiful. Hollywood can take its endings. I'd rather have the real thing.
