Everything in this phenomenal world has at least one thing in common: it all had a beginning, and it all will come to an end. The length of time, as we measure it, between beginning and end may be fractions of a second or millions of years, yet every form of physical life has a beginning and an end. Within the experience of a human lifetime, we have innumerable beginnings and endings. Every breath, every activity, every relationship has a beginning and an end. Our physical body had a beginning, and it will have an end. Each beginning is a type of birth, each ending a type of death.
Some of the most quoted words of the Bible are from the Book of Ecclesiastes, chapter 3, verses 1-8:
Have you ever wondered about the reason for things? Have you wondered why you are where you are in life, why you are doing what you are doing, why your life seems to have taken the turn it has? Even though you cannot answer these questions from a human standpoint—that is, not really answer them—you can find a satisfactory answer in the realization of the truth about yourself. If you realize that you are a spiritual being, a living soul sent out from God, that your life is without beginning or end, you can begin to see yourself and the events of your life from a different perspective. You are essentially a spiritual being, but you are at the same time a human being.
