Let’s be honest with ourselves when we are talking about our faith. Some days you walk on water and other days you sink like a stone. Faith invariably gives way to doubt before it again recovers its confidence, then it loses it again.
Remember the story of Peter walking on water. The story goes this way: The disciples had just witnessed a major miracle, Jesus fed more than 5000 people with five loaves of bread and two fishes. Having just witnessed a miracle, their faith was strong. Soon afterwards they get into a boat to cross a lake. Jesus is not with them. A few miles out they run into a fierce storm and begin to panic. Jesus comes walking towards them on the water. Initially they’re frightened and take him for a ghost. But he calms their fear by telling them, right from the center of the storm, that he is not just Jesus but that he is God’s very presence.
Peter is immediately buoyed up in his faith and asks Jesus to let him too walk on the water. Jesus invites him to do so and Peter gets out of the boat confidently and begins to walk on the water. But then, realizing what he was doing and the incredulous nature of it, he immediately starts to sink, cries out for help, and Jesus has to reach out and rescue him from drowning.
What we see illustrated here are two things that lie at the heart of our experience of faith, namely, that faith (literally) has its ups and downs and that it works best when we don’t confuse it with our own efforts.
Faith has its ups and downs. Our own faith works exactly like
that, at times it lets us walk on water and at other times we sink like a
stone. The gospel-image of Peter walking on the sea speaks for itself.
