In John 4 we hear the conversation with Jesus and the woman at the well. When Jesus asks her for a drink; her reply was; "Thou hast nothing to draw with, and the well is deep: from whence then hast Thou that Living water?" And everyone no doubt knows what Jesus' response was ..? John 4:10 "Jesus answered and said unto her, If thou knewest the gift of God, and who it is that saith to thee, Give me to drink; thou wouldest have asked of him, and he would have given thee living water."
