This whole "walking on water" business is hard for me to grasp. I don't know if it's because I grew up in a church that relegated miracles to the annals of history, if it's because I'm too concrete and logical, or it's because I have never seen such a miracle and lack faith. I do like to know things from experience, or at least be able to explain how they might be possible... and I can't with this story. But let's leave that thought where it is.
What I love about this passage is the following: Peter went through just about every possible emotion in the course of one day - elation, frustration, terror, bravado, doubt, fear, humiliation, confusion and awe. What a day!
The humanness of Peter - screaming like a sissy one moment and daring Jesus to give him superpowers the next - makes me smile and somehow encourages me tremendously. We're all a little bit like Peter, aren't we? Boastful and on top of the world one moment and running to our mommies the next, licking our wounds. We're human, in other words. Flawed but beautiful, full of emotions and life.
Some days are like that. It's okay. Embrace the moment and the emotion, because Jesus is right there, loving and laughing and crying with you... and that is a miracle in which I can easily believe.
