As defined, a mystery is “Something that is difficult or impossible to understand or explain.” To solve a mystery we look for clues, relying upon deductive reasoning. Some mysteries are more easier to solve than others. For example, when we consider the general revelation of the universe, when we look at the splendor of the heavens and earth, it is not difficult to deduce that it was designed and created by God: Indeed, “his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made” (1:20). It is not difficult to solve the mystery of creation’s origin, even a child can deduce it. It is only the fool who says in his heart, “There is no God” (Ps. 14:1).
