There seems to be a resurgence of television shows that involve some form of time travel.  This really shouldn't surprise us because all of us have moments in our past that we wish we could have done differently.  This is true for us as a people and for us individually.  However, consider this.  Jesus is God.  He is the One who created time.  And yet, He chose to humble Himself by entering time and space.  He willingly submitted Himself to the these limitations.  Why?  Not to correct His past mistakes and not to change His future.  Rather, Jesus came to pay the penalty for our past mistakes and to change our futures forever.
