Human existence can be described by this allegory: You open your eyes and find that you are in a large room filled with people. You ask someone, “Where am I?”, “Why are we here?” No one seems to know. As you look around, you notice that there are two doors. From time to time, one door opens and someone walks into the room. They open their eyes and ask, “Where am I”, “Why am I here?”. You try to look through the doorway and see what’s on the other side, but it’s all black. You can’t see anything. From time to time, the other door opens and someone walks out of the room. You try to see what’s on the other side of the door, but you can’t see anything. That’s life. That describes the situation in which we all find ourselves, which leads us to four basic questions: “Where did we come from?”, “Why are we here?”, “How should we live?”, and “Where are we going?”. None of the answers are self-evident, even though opinions abound.
