The tendency in our spiritual life but also our more general attitude toward love is that our feelings are all that is going on. And so to us the totality of love is what we feel. But to really love someone requires commitment, fidelity and vulnerability. Mother Teresa wasn't "feeling" Christ's love, and she could have shut down. But she was up at 4:30 every morning for Jesus, and still writing to him, "Your happiness is all I want."
