Note: As the Church has said, the manual has been prepared as the primary source of lesson material. These supplements, from general conference addresses, are meant only as a complement to your study on this lesson’s topic.
Supplement is from Elder Robert D. Hales' talk "The Covenant of Baptism: To Be in the Kingdom and of the Kingdom" from October 2000 general conference:
At baptism we make a covenant with our Heavenly Father that we are willing to come into His kingdom and keep His commandments from that time forward, even though we still live in the world. We are reminded from the Book of Mormon that our baptism is a covenant to “stand as witnesses of God [and His kingdom] at all times and in all things, and in all places that ye may be in, even until death, that ye may be redeemed of God, and be numbered with those of the first resurrection, that ye may have eternal life” (Mosiah 18:9; emphasis added).
When we understand our baptismal covenant and the gift of the Holy Ghost, it will change our lives and will establish our total allegiance to the kingdom of God. When temptations come our way, if we will listen, the Holy Ghost will remind us that we have promised to remember our Savior and obey the commandments of God...
The scriptures confirm that the truly converted do more than just forsake the enticements of the world. They love God and their fellowmen. Their minds and hearts are centered on the Savior’s atoning sacrifice. From the moment of their respective conversions, Enos, Alma the Younger, Paul, and others turned wholeheartedly to the task of bringing themselves and their fellowmen to God. Worldly power and possessions lost their former significance. The sons of Mosiah refused an earthly kingdom and risked their lives for the sake of others. These faithful sons were driven by the hope that they might be able to help save even one soul—thus winning for themselves and their brethren a place in God’s eternal kingdom.
