The first recorded instruction given to Adam after the Fall dealt with the eternal principle of work. The Lord said: "In the sweat of thy face shalt thou eat bread." (Gen. 3:19.) Our Heavenly Father loves us so completely that he has given us a commandment to work. This is one of the keys to eternal life. He knows that we will learn more, grow more, achieve more, serve more, and benefit more from a life of industry than from a life of ease.
