Ecclesiastes 2:14 says, The wise man’s eyes are in his head; but the fool walketh in darkness: and I myself perceived also that one event happeneth to them all.  I believe Solomon was saying that God gives us light to walk by, if we are willing to look to Him.  Those who will not follow God are find themselves wandering around in the darkness.  We as followers of Christ have been given the Holy Spirit to guide our steps and light our path, and if we refuse to allow Him to do so, we are indeed foolish.  We will never find happiness in the darkness of sin.  Whether wise or foolish, though, ultimately death comes to both.  Verse fifteen says, Then said I in my heart, As it happeneth to the fool, so it happeneth even to me; and why was I then more wise? Then I said in my heart, that this also is vanity.  Solomon seemed to be questioning what advantage there was to living in wisdom when both the wise and foolish die.  If we look at life as being only this time on earth, that might be a valid observation, but we know we have life everlasting and God expects us to use our time here wisely.  We cannot live life as though everything here is all that matters.  Verse sixteen says, For there is no remembrance of the wise more than of the fool for ever; seeing that which now is in the days to come shall all be forgotten. And how dieth the wise man? as the fool.  We may remember a few people throughout history for things that they did, whether good or bad, but for the most part, we soon pass into oblivion in the eyes of the world once we die.  As followers of Christ, though, we can be certain that we will never be forgotten by Him.  He gives us light and purpose in this world and everlasting life in the one to come, if we only accept it.
