Luke's surgery is almost over!

I just received an update from Luke's daddy, Ed and Luke's grandmother, Mammee (pronounced Ma-mee).  They are over half-way through with Luke's surgery.  Everything is going well.  The doctors are getting ready to take Luke off the bypass machine and then they will need to restart his heart.  That just sounds so frightening to me.  Hopefully Luke will be in recovery within 1-2 hours.  Please keep praying!
