Jesus speaks about living water to the Samaritan woman at Jacob’s well.

 Jesus said to her , “Everyone who drinks of this water will be thirsty again, but those who drink of the water that I will give them will never be thirsty. John 4:13-14

Living Water is Him.  His Presence so fills us so that spending time with Him, one to One, gives us all that we desire.  In His Presence we are complete– with our will submitted to His will.  We are His children in His Presence.
