The tree and its fruit represent the love of God (see 1 Nephi 11:25). The fruit is desirable above all other things to make one happy. The love of God is expressed through the Lord Jesus Christ and His atoning sacrifice (see John 3:16). The ultimate gift from God through His Son is eternal life (see D&C 14:7)—where we dwell with God in a state of never-ending happiness (see Mosiah 2:41). We receive this love as we come unto Christ and partake of His atoning sacrifice through obedience to the doctrines and principles of His gospel.
