Isaiah 58:11

The Lord will guide you continually, and satisfy your soul in drought, and strengthen your bones; you shall be like a watered garden, and like a spring of water, whose waters do not fail.

The promise of God to continually guide us and satisfy our soul in drought is real.  God promises to keep us fresh and strengthen us with His word.  As we daily maintain contact with the word and renew our minds, He guides us in the way we should go.  A watered garden is green and flourishing, and with God, so will our lives be.
