MISSION TO PLANET EARTH - Third Grade The Mission to Planet Earth emphasizes equipping third graders to fulfill Jesus’ call to be His witnesses and His light to the world. As “shining stars” the cadets learn how to obey God’s 12 representatives by studying the book of Acts and the lives of great, historical missionaries. The preparation for their life’s mission includes studying the Keys to the Kingdom, a system that teaches them how to become a Christian and what it means to be a Christian. Their lessons are taught on board the Starship Redeemer, captained by Ambassador Lightbearer and first mate, Pixel. After a year of training, concluding with an “invitation” of Planet Earth, the children are launched into their mission as life-long ambassadors for Christ.
