A person can survive between one and two months without food. But a person can survive only two to three days without water. Water is one of our greatest needs. Research shows that even slight dehydration will adversely affect your mood, memory, and motor coordination. Become seriously dehydrated, and life ends quickly.

This helps us understand what Scripture means when it says things like, “My soul thirsts for God” (Psalm 42:2). If one is separated from God, he is adversely affected. If he remains separated from God, he will die an agonizing eternal death. Not all admit it; yet it remains true for all.

Everyone has a deep spiritual thirst. In our heart of hearts, we all long for everlasting life. Unbelievers try to satisfy that deep thirst with worldly things, a strategy doomed for failure. Believers look to the One who has promised, “Whoever drinks the water I give them will never thirst.” Jesus meets our greatest needs. He alone possesses the water that satisfies those who are spiritually parched. He alone grants eternal life.
