What people believe is a powerful part of being human, beliefs shape our thoughts and our actions. But what if those beliefs are not based on what's true and good? Christian author Abdu Murray says we actually live in what's called a "post-truth" world, one that puts feelings ahead of facts. In his new book, "Saving Truth," Murray says that because we've lost sight of truth, we actually live in a culture of confusion. He says, "What happens if my preferences conflict with someone else's preferences? And if truth doesn't decide who's right and who's wrong, what decides who's right and who's wrong won't be truth, it will be power."
