This verse is a reminder to turn to The Lord when you are young, before life slips away from you.
We are all under the delusion that we have a tomorrow and that we will turn to The Lord then. As James said; our life is but a mist. We are not here long and before we know it our time is up.
We are not guaranteed a tomorrow, all we have is today. So today is the day to remember our creator and turn to him. Whether we have obeyed the gospel or we haven't yet, today is the day to repent of the disobedience in our lives and follow his ways.
So today, lets remember our creator before time goes by and all is lost.
2/12/14 Leo J. Woodman
