Don't work for the food which perishes, but for the food which remains to eternal life, which the Son of Man will give to you. For God the Father has sealed him."
To everlasting life - The strength derived from the doctrines of the gospel is not exhausted. It endures without wasting away. It nourishes the soul to everlasting life. “They that wait upon the Lord shall renew their strength; they shall run and not be weary, and shall walk and not faint,” Isaiah 40:31.
