You only live once--if then. Life is short, and it can be as easily wasted as lived to the full. In the midst of our harried modern world, how do we make the most of life and the time we have? In these fast and superficial times, Os Guinness calls us to consequential living. In strong contrast to both Eastern and secularist views of time, he reorients our very notion of history, not as cyclical nor as meaningless, but as linear and purposeful. In the Judeo-Christian tradition, time and history are meaningful, and human beings have agency to live with freedom and consequence in partnership with God. Thus we can seek to serve God's purpose for our generation, read the times, and discern our call for this moment in history. Our time on earth has significance. Live rightly, discern the times, and redeem the day.
