RC 243.8
(Reflecting Christ 243.8)
Parents, teach your children regarding the things that are coming upon the earth, and lead them to prepare to meet their Lord in peace. Gain a knowledge of the Scriptures. Do not fill the head with the nonsense of novels. Brain nerve power is required by those who desire to comprehend the truth so clearly that they can teach it intelligently to others. We have none too much brainpower. Never can we afford to use tobacco, or alcoholic liquors, or any other injurious substance; for we must strive to keep our minds clear for the work of saving souls. The Lord is pleased with those who manifest fervid earnestness in His service. It is the privilege of everyone to cultivate faithfully every God-given power. (RC 243.8) MC VC
