John 4 - a fountain of living water within

Jesus has more in mind that quenching your first on a weekly basis. There are many streams, even in Christianity that you can drink from, that will leave you thirsty again. In Jesus' conversation with the Samaritan woman he reveals a source of living water that will leave us continually satisfied.
Correction: Where I spoke of Agnostic, I meant Gnostic! ...thanks for the understanding :)
