Never will you understand the necessity of a negative message, a message of warning - than you will when you see the latter end of someone who ignores then when they are given. That is the case here as we look at this next to last verse of chapter one of Proverbs. This verse lets us know that the unwise moral and spiritual choices of the fool cost him dearly at the end of his life. Actually, here we learn that these choices may be what ends his life.
The first thing of which we are warned here is imitating the "waywardness" of the naive. To be wayward is to be one who turns away from God and His Word. The Hebrew word here is "mesubah" and it means to turn away, to be apostate, or to backslide. What it refers to is someone who is constantly fluctuating or vacillating in their views. This describes the ones who turn away from the Word. Their "open-mindedness" that describes their naive thinking will constantly change and morph as society itself does. In time, they will have one view - but change to another. This accurately describes the reason that the morals of society seem to constantly be in flux. But the part of this that is frighening is that we read here that it is these very tendencies that will kill them. Their naivete is that they can order their own lives and have no real consequences from such choices. The truth though is that by turning away from the Lord, they will face judgments and severe consequences, the most severe of them being what will happen to them after they die and face the final judgment before God.
The second thing we see here is that the complacency of fools will destroy them. Complacency here is the Hebrew word, 'salway" and it speaks of a sense of security and quietness in one's prosperity. There is no anxiety or concern. There is only an excessive easy and prosperity. They take the lack of trouble as a sign that everything is fine and there is no need to even be concerned about eternal matters. The problem for them is that there is very real trouble in their future - but their attitude toward God's Word keeps the from knowing the danger.
There is a need for messages that warn and correct us. If we could guarantee that we would life perfect lives that never need correction, we could blow off these kind of things. But the fact of the Biblical worldview is that we are fallen, sinful people who are prone to rebellion and disobedience. This necessitates that we have to be warned of the consequences of unbiblical choices. We need to be reminded that there are very real, very negative results that come with walking apart from God's revealed will in His Word. Hopefully, such warnings will turn us away from ungodly choices and lifestyles. Hopefully we will hear such things and not trust in ourselves - but in God who guides us into paths of righteousness and blessing.
