Before you finish reading this sentence, approximately one hundred billion (100,000,000,000) operations will have been completed inside your eyes. However fantastic it may seem, you possess an example (two, in fact) of the Universe's ultimate technology. No scientist has ever come close to fully grasping it, let alone inventing anything remotely similar. Whatever you have in your life is meaningful through your senses—vision and others. Without eyes, you could never imagine colors, forms, scenes, human faces, or what the word beauty means. But you do have eyes, and thanks to them, you can now read these printed words before you. Nor does the act of vision cost you very much effort. To see an object, all you have to do is to turn your gaze at it. Nor did you have to struggle to develop a pair of those wonderful instruments. At birth, your eyes came as standard equipment, with free installation and, unless you had a particular defect, in perfect working order. Since then, you’re not likely to have felt any urge to ask the kind of questions you might upon receiving an expensive, anonymous gift, such as “Why did I get this?” or, “Who sent this to me?” or, “Exactly what do they want from me in return?.” Be assured that the Creator, Who lent you this blessing, will call you to account when the contract ends—which is sooner than you imagine.
