(Friend Nov 2004, suggestion # 3)
To help the children understand that fasting can bring them closer to Heavenly Father and His Son Jesus Christ and that our families are strengthened and blessed through fasting and prayer, show "The Law of the Fast" from the Family Home Evening Video Supplement (item no. 53276).
To fast is to go without food and drink. When we are willing to fast and pray, we show Heavenly Father and Jesus Christ that we love them and are trying to keep the commandments so we can receive their help.
We need Heavenly Father's help all the time, but there are times when we have a particularly difficult problem to solve or when someone in our family is very ill.
That is when we can also fast on days other than fast Sunday.
Invite two or three families to share an experience of when a family or family member has fasted and prayed for the Lord's help. Have them express how they were blessed and strengthened through this experience.
Sing "I Feel My Savior's Love" (pp. 74–75). (Note: Young children should not be expected to fast. "Neither should parents compel their little children to fast" [Joseph F. Smith, Gospel Doctrine, 244].)
