The world in which we live is troubling. As Christians, we must understand where the trouble comes from. It is easy to list many reasons for the wrongs we observe: disease, natural disasters, wars, etc., but the root cause, the real reason for the troubles we have is sin—sin and its impact on creation. Sin brings trouble and discord. Sin has brought trouble to relationships, sickness and inherited diseases to untold millions throughout history—and the list could go on. So whether directly or indirectly, the darkness in the world and in our lives comes from sin.
