Water is known for two important uses cleansing and relieving thirst. Those who are not yet baptized do not have Jesus in them, thus they thirst for Him. The grace of being united with Jesus, thus ending the thirst for Him, is signified by water. Also, just as water is used for cleansing, its use in Baptism symbolizes and brings about cleansing from all sin. Freed from sin, the baptized are reborn to new life.
