He giveth power to the faint; and to [them that have] no might he increaseth strength. Even the youths shall faint and be weary, and the young men shall utterly fall: But they that wait upon the LORD shall renew [their] strength; they shall mount up with wings as eagles; they shall run, and not be weary; [and] they shall walk, and not faint. (Isaiah 40:29-31)

Though we struggle to walk in the light and grow weary in the work of the Lord, our gracious Father is always there to renew us in His strength and power. By the might of God's word, we are encouraged and brought to a place of rest in His wonderful peace and love.
