When I was baptized I made a covenant to take upon me the name of Jesus Christ and to serve Him and be obedient.
Heavenly Father has given me the Holy Ghost. Through the Atonement of Jesus Christ, I can be forgiven of my sins when I repent. If I keep my baptismal covenant, I can return to live with Him.
When I take the sacrament, I renew my covenant to take upon me the name of Jesus Christ, to always remember Him, and to obey His commandments. When I do this, I can feel the Holy Ghost guiding me.
