We can face any challenge​—all because Jehovah is our Grand Instructor. (Isa. 30:20, 21) His Word gives us everything we need to be “fully competent” and “completely equipped for every good work.” (2 Tim. 3:17) When we live by Bible teachings, we become wiser than those who promote “the wisdom of this world.” (Ps. 119:97-100) Regrettably, the wisdom of the world often appeals to our fleshly desires. So we might find it difficult to resist thinking and acting like those who are part of the world. For good reason, the Bible says: “Look out that no one takes you captive by means of the philosophy and empty deception according to human tradition.” (Col. 2:8) As the Bible foretold about the last days, people would to a remarkable degree become “lovers of pleasures.” (2 Tim. 3:4) The prevalence of sexually transmitted diseases, such as AIDS, is just one indication that the wisdom of the world is foolishness.​—2 Pet. 2:19. w19.05 21 ¶1-2; 22 ¶4-5
