"In computing the duration of a human life in the actual sense of life, if we wish to obtain the result in minutes and seconds, we must strike out from the calculations all those minutes and seconds in which he does not live in the proper sense of the word. This would include all periods of unconsciousness, of intoxitcation, and of mental alienations, -- in short, all moments which, when past, leave in our nature no rational record of their passage." Charles E. Sargent, M.A.
When I read the above quote it made me think about the scripture in 1 Peter 3:10, "if we would love life and see good days", then surely we must consider how much of our life is worth the living.
Like the quote suggests, if we consider the time spent in worry, resentment, anger, discouragement, all mental alienations, or mental derangements, from friends, family, co-workers or whoever; we must consider that time spent, is life not worth the living. That term mental alienations stuck out the most to me, and truly life in that state is lost time. So much of our time can be lost if we do not follow the Path.
As a Christian, our lives are in God's hands, every man our brother, every task a purpose, every trial a lesson, so that we can glorify God and enjoy Him forever, as the catechism states.
