2 Thessalonians 2:7–12 warns that the "mystery of iniquity" is the growing power of deception in the world. When people reject the truth of God's Word, God allows them to believe lies, because man has a free will to chose good or evil. The real mystery is how intelligent people can call evil good and good evil—but it happens when they refuse to love the truth. Throughout history people have justified great evil while believing they were right. The root problem is abandoning God's authority and replacing it with human opinion. Without the Bible as the final authority, morality collapses and society drifts into confusion and delusion. The only safeguard is a personal return to God—loving His truth, living by His Word, and refusing to be shaped by the lies of the age.
