The Gospel is all about walking.
Today's passage from Matthew 14:22-33 is all about walking. First, you have Jesus walking on the water, and the disciples thinking it was a ghost. "It is I; don't be scared" was his response.
Peter then says "Lord, if it is you (as if), command me to come to you on the water."
Peter started walking on the water...and then he sank.
Jesus says to us all: Walk! Follow me.
Jesus doesn't say how far, where, or when we can stop, or if we ever really stop.
Just said "Come" and "Follow me."
The rest is history...or story.
