How many times have we disappointed Jesus, or God our Father? How many times have we felt such remorse that it drove us to our prayer closets in deep contrition, and how many of us cry tears of remorse? Peter wept when he realized that not only had he denied Christ, but that Jesus knew this was going to happen even as he was pledging his love and dedication... so great is the love of Jesus for us that he loves us while we are yet sinners, and can see our coming tears, even hearing our contrition as an echo.
