(Friend Dec. 2004, suggestion # 1)
Show a picture of the Last Supper (GAK 225).
Before Jesus' Crucifixion, He broke the bread, blessed it, and commanded that those who were with Him partake of it. Jesus gave His Apostles the sacrament so that they would have a way to always remember Him and His sacrifice and so that they could have His Spirit to be with them. The sacrament is a covenant to remember Him and to keep His commandments. Read together Luke 22:19.
Show a picture of Christ visiting the Nephites (GAK 316). Following His Resurrection, Jesus Christ appeared to the Nephites on the American continent. During this visit, He taught the people how to prepare and partake of the sacrament. The Savior broke the bread, blessed it, and commanded that the disciples who were with Him partake of it. Read together 3 Nephi 18:6–7. The Savior also blessed the wine (we use water now—see D&C 27:2) and commanded the disciples to drink of it. Read together 3 Nephi 18:11. Jesus Christ taught the disciples that when they partook of the sacrament, they were renewing their baptismal covenants to always remember Him, to take His name upon them, and to keep His commandments.
Show the pictures of blessing and passing the sacrament today (GAK 603 and 604). We can participate in the same ordinance that Jesus taught. The sacrament prayers tell us that if we remember Jesus Christ and keep His commandments, we will always have His Spirit with us. He wants us to remember Him so we can be strong and faithful. Read the sacrament prayers in Moroni 4:3 and 5:2.
Remind the children that without the Atonement, which we remember as we take the sacrament, we would not celebrate Christmas. To reinforce this teaching moment, sing "The Sacrament" (p. 72), "I'm Trying to Be like Jesus" (pp. 78–79), or a favorite sacrament hymn. If the song or hymn is new for the children, sing one line at a time and have them echo it back to you. Bear testimony that we can remember the Savior when we take the sacrament and try to become more like Him.
