Don't be so sure of yourself...

As we look at this failure in Peter's following after Jesus, the most striking point is that he was the most courageous and confident of the apostles, often willing to speak up and step out of the boat when none else would.  In other words, we would be no different.  Even in his failure, he followed longer and closer than the rest.  He falling fell in the fact that he was relying on his own faithfulness, rather than relying on the grace and strength of Jesus.  And that is where we usually fail as well - trying to show God how strong we are, instead of relying on how strong He is.  Take heed, lest ye fall.
