The group "NeedtoBreathe" has a great song titled "Walking on Water." Their lyrics correctly capture the essence of the story --that faith doesn't empower us to walk on water, but rather, Jesus is teaching us that he saves when we falter and sink in the storms.
Supporting Members: I've linked to the "Walking on Water" video clip and discussed the lyrics over here in the post below the "Peter Sinks~Jesus Saves" Writing Team lesson --which also includes a lesson plan for showing and dramatizing the video in a creative way.
