“I counsel all of you brethren to avoid every kind of addiction. At this time Satan and his followers are enslaving some of our choicest young people through addiction to alcohol, all kinds of drugs, pornography, tobacco, gambling, and other compulsive disorders. Some people seem to be born with a weakness for these substances so that only a single experimentation will result in uncontrollable addiction. Some addictions are actually mind-altering and create a craving that overpowers reason and judgment. These addictions destroy the lives not only of those who do not resist them but also their parents, spouses, and children. As the prophet Jeremiah lamented, “The kings of the earth, and all the inhabitants of the world, would not have believed that the adversary and the enemy should have entered into the gates.” “The Lord in His wisdom has warned us that substances that are not good for us should be totally avoided. We have been warned not to take the first drink, smoke the first cigarette, or try the first drug. Curiosity and peer pressure are selfish reasons to dabble with addictive substances. We should stop and consider the full consequences, not just to ourselves and our futures, but also to our loved ones. These consequences are physical, but they also risk the loss of the Spirit and cause us to fall prey to Satan.”
