Approximately 70% of the human body is composed of water. A deficiency of just 2 % of the water causes us to feel extreme thirst. Spiritually, water refers to the word of God. As water is absolutely necessary for our bodies to survive, the word of God is necessary for the survival of our spirits. To the same extent that we live by the word of God, our spirits will be restored, everything we do will be successful, we will enjoy good health, and in the end, we will enter heaven.
"The law of the Lord is perfect, restoring the soul."(Psalm 19:7)
