We all followed Jesus in the pre-mortal life. We all fought to keep our agency and be allowed to choose in this life.
I used this one in Primary many years ago - First I had the kids count off, 1, 2, 3, 1, 2, . . . so that each child was assigned a number 1, 2, or 3.
Then I had those with the numbers one and two go to one side of the room and those with the number 3 go to the other side of the room.
Ahead of time I had chosen 2 young men to take the parts of Jesus and Lucifer. Then we read scriptures talking about the war in heaven and how one third of the hosts of heaven were lost.
I had the kids look across the room at each other and ask themselves if they think it was easy to battle against friends / family members.
Then I told the #3 kids to go and join the #1 and #2 kids and explained that all of them had chosen to follow Jesus. How did I know? They were here.
(Jenny says: As of today (Nov 16, 2018) The current Church Handbook of Instructions Book 2 Section 13.6.15 has some new instructions on the portrayal of Deity. "If the Savior is portrayed, it must be done with the utmost reverence and dignity. Only brethren of wholesome personal character should be considered for the part. The person who portrays the Savior should not sing or dance. When speaking, he should use only direct quotations of scriptures spoken by the Savior. At the end of the performance, the person should not wear the costume in the foyer or elsewhere. He should change immediately into street clothes. The Savior should not be portrayed by children in dramatization except in a nativity scene.")
