John 4:10 Jesus answered and said to her, “If you knew the gift of God, and who it is who says to you, ‘Give Me a drink,’ you would have asked Him, and He would have given you living water.”
Think about what Jesus is saying He is giving this woman? Is it the Holy Spirit? Somehow I don’t think so; I think it is more likely to the Himself.
Jesus was going to give Himself for those people who did not yet believe. This woman became a believer based on what Christ was telling her.
Christ was giving a beautiful picture of His own sacrifice which was needed before she could become a believer and receive the Holy Sprit.
