The reality of imminent death has a way of enhancing what really matters in life. The greatest waste of a life begins when a person is convinced that life is unimportant and spend it on frivolous living. At the end of the day there will be nothing carried over to the following day. We will spend it somehow, even if we lay in bed all day sleeping and then sit up half the night watching television. We should recognize each day how we have spent our allotment and determine what we will do with the balance.
Wasting life is a sin.
The apostle Paul lived his life as if his life could end any moment. Such an idea, when preached today, is considered to be negative and oppressive. Many consider the idea of full surrender to God a legalistic notion unsupported by the Scriptures, so they capitulate to the hypnotic call of the World System and manage to keep their ears and minds free from anything that would convict them to do otherwise. As a result, many professing Christians are subject to hopelessness and may battle feelings of emptiness and unworthiness. This self-inflicted disorder keeps vain religion in business as psychological support for people with collapsing faith systems.
