Why is Christ called the 'water of life'?

In Scripture, Christ is designated as the 'water of life' because He satisfies the deepest spiritual thirst of humanity. John 4:14 emphasizes that whosoever drinks of the water Christ gives will never thirst again, referring to the eternal life and fulfillment found in Him. As believers, we draw from Him not only for salvation but for ongoing strength, joy, and sustenance throughout our lives. This metaphor signifies that spiritual life and vitality are entirely derived from Christ, illustrating the necessity of ongoing reliance on Him for all aspects of existence.
