This quote from Einstein was a great introduction to the sermon ("Danger Sign?") last week. Jesus helped people see things differently: Himself, Suffering, Others and, last week, Danger. Its not that Jesus doesn't see danger, it is just that he puts up "Danger!" signs in different places than we do. We think its dangerous when we are vulnerable or out of control. Jesus sees danger when we are self satisfied and think we are in control.
The story we read was Matthew 14:22-33 where Jesus walks on water- and then invites Peter to join him. One of the other quotes I used was from John Ortberg (who wrote a whole book based on this story):
"There is something inside of you that wants to walk on water- to leave the comfort of routine existence and abandon yourself to the high adventure of following God."
