Display a small, clear container of clean water inside a larger container of dirty water. Point out that it is possible for the water in the small container to remain pure even when it is surrounded by filthy water. Liken the clean water to people who are trying to live clean lives in an evil world. It is possible for us to remain pure and righteous if we do not allow any impurity or unrighteousness into our lives. Tell the children that in this lesson they will learn about Enoch, an Old Testament prophet, who was pure in heart.

Teach the children the account of Enoch from the scriptures listed in the “Preparation” section. (For suggested ways to teach the scripture account, see “Teaching from the Scriptures,” p. vii.) Emphasize the following points about Enoch’s life:

• When Enoch was first called to be a prophet, he felt inadequate. He was young and “slow of speech” (Moses 6:31), but he exercised faith and obeyed the Lord’s will.

• Enoch talked with the Lord face to face and saw many visions. He prophesied of the Restoration of the gospel and the coming forth of the Book of Mormon (“truth will I send forth out of the earth” [Moses 7:62]), the preaching of the gospel to all the world, the building of the New Jerusalem, and the ushering in of the Millennium.

• Enoch taught, helped convert, and baptized many people, who became so righteous that they lived in a “City of Holiness, even Zion” (Moses 7:19).

• This holy city was “taken up into heaven” and will return at the time of the Millennium. When it returns it will join with the earthly Zion, which is the New Jerusalem.

Study the following questions and the scripture references as you prepare your lesson. Use the questions you feel will best help the children understand the scriptures and apply the principles in their lives. Reading and discussing the scriptures with the children in class will help them gain personal insights.

• How did Enoch receive his calling? (Moses 6:26–27, 42.) What was Enoch called to do?

• How were most of the people living at the time Enoch received his call? (Moses 6:27–29.)

• Why did Enoch feel his calling was too difficult for him? (Moses 6:31.) What specifically did the Lord tell Enoch to do before he would be blessed? (Moses 6:32.) What did the Lord tell Enoch to say? (Moses 6:33.) How were the Lord’s promises in Moses 6:34 fulfilled? (Moses 7:13.)

• Think of a time when you struggled or had a problem that was difficult. What can you learn from Enoch’s example in dealing with challenges? (See enrichment activity 1.)

• What can we learn about the Lord from Enoch’s visions? (Moses 7:4.) What did Enoch learn about the people of the world? (Moses 7:41.)

• Display the picture The City of Enoch. How were the people who heard and obeyed Enoch’s words blessed? (Moses 7:16–17.) Why was their city called Zion? (Moses 7:18–19.) What do you think it means to be “of one heart and one mind”? How can you help your family be more like the people who lived in Zion? (See enrichment activity 4.)

• What happened to Enoch and all the people in the city of Enoch? (Moses 7:21, 69; D&C 107:49.) What does it mean to be “taken up into heaven,” or translated? Help the children understand that when people are translated, their bodies are changed so they will not experience pain and will “never taste of death” (3 Nephi 28:7). At the time of the Second Coming they will “be changed in the twinkling of an eye from mortality to immortality” (3 Nephi 28:8).

• Why did the Lord weep? (Moses 7:28, 32–33.) How do you want your parents and the Lord to feel when they see your actions? How do we know that each individual is important to the Lord?

• When Enoch wept, how did the Lord comfort him? (Moses 7:44–45, 47.) How can thinking about Jesus Christ and his love and sacrifice for us comfort us even though there is great wickedness in the world?

• When will Zion, or a city of the pure in heart, again be established? (Moses 7:62.) What is the “truth” that must “sweep the earth” to prepare for the establishment of Zion? (President Ezra Taft Benson defined this truth as the Book of Mormon [in Conference Report, Oct. 1986, p. 102; or Ensign, Nov. 1986, p. 79.) How can we help fulfill this prophecy about the Book of Mormon?

• Where will Zion, the New Jerusalem be located? (Articles of Faith 1:10.)

• How long will Jesus Christ dwell on the earth with the righteous in Zion? (Moses 7:64–65.) Point out that this period of one thousand years is called the Millennium.

• How can you take part in preparing for this joyous time when Zion will be established? (See enrichment activity 3.)

You may want to bear testimony that being pure in heart as Enoch and his people were brings happiness. Encourage the children to decide on one or two specific things they can do during the coming week to become more pure and thus help others around them become better also.

Encourage the children to share with their families a specific part of the lesson, such as a story, question, or activity, or to read with their families the “Suggested Home Reading.”

Suggest that the children study Moses 7:18–21 at home as a review of this lesson.
