Ecclesiastes 6:10-12 (ESV)
10 Whatever has come to be has already been named, and it is known what man is, and that he is not able to dispute with one stronger than he. 11 The more words, the more vanity, and what is the advantage to man? 12 For who knows what is good for man while he lives the few days of his vain life, which he passes like a shadow? For who can tell man what will be after him under the sun?

Quoting Matthew Henry, �Solomon lays down his conclusion which he had undertaken to prove, as that which was fully confirmed by the foregoing discourse: There be many things that increase vanity; the life of man is vain, at the best, and there are abundance of accidents that concur to make it more so; even that which pretends to increase the vanity and make it more vexatious��. Thoughtful people are in care to do everything for the best, if they knew it; but as it is an instance of the corruption of our hearts that we are apt to desire that as good for us which is really hurtful, as children that cry for knives to cut their fingers with, so is it an instance of the vanity of this world that what, according to all probable conjectures, seems to be for the best, often proves otherwise; such is our shortsightedness concerning the issues and events of things, and such broken reeds are all our creature-confidences. We know not how to advise others for the best, nor how to act ourselves, because that which we apprehend likely to be for our welfare may become a trap. �

Ever since Adam and Eve took from the Tree of Knowledge of Good and Evil, man has been searching in vain to understand what is good and what is evil. In fact most of what we call religion is based on man�s search to understand the difference and to establish good in the lives of people. What we forget is God was right there with Adam and Eve to explain the difference. In their walks with God they had the opportunity to listen to God and hear directly what we might tell a child, �Don�t touch that or you will get burned.� Sin burns when we can�t see it for what it is. We need to stop trying to find out for ourselves what is good and what is evil and instead turn to God for the answers. We need to fellowship with God, listen to what He says and put His words into action. The Bible like a diary does not replace teaching us who a person is, but tells us about their thoughts. If we want to know them intimately then we need to spend time with them and grow in our relationship with them. We need to do that with God so we understand His will for our lives.
