Trust in Divine Power
The Saviour of the world loves to have children and youth give their hearts to Him. There may be a large army of children who shall be found faithful to God, because they walk in the light as Christ is in the light. They will love the Lord Jesus, and it will be their delight to please Him. . . .Through childhood and youth they will be found faithful disciples of our Lord.  Adventist Home, p. 297

Temperance
We are not to indulge in any habit that will weaken physical or mental strength, or abuse our powers in any way. We are to do all in our power to keep ourselves in health, in order that we may have sweetness of disposition, a clear mind, and be able to distinguish between the sacred and the common, and honor God in our bodies and in our spirits, which are His.  Child Guidance, p. 364
