A prudent or wise person is able to see the evil around him.
Some foolish people are not even able to see the dangers around. A foolish man might say, “I can enjoy much of the worlds entertainment and pleasures and they won’t hurt me or my family.” But he never realizes how spiritually dull he actually becomes, how worldly his kids become, or how his hunger for more sin is fed through that “innocent” entertainment or activity until it becomes insatiable.
A prudent person hides himself.
First he must notice it and then he must do something about it. Like a person who might see a band of thugs coming down the street beating and shooting people, and he hides from them so he doesn’t get beat or shot, the wise person sees the danger of more subtle things in this world and hides. He gets away from them before they destroy him.
The naïve continue.
A naïve person is a simple person, one who simply doesn’t get it. He doesn’t understand what is going on around him. Satan has blinded the eyes of the people of this world,
“In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them ” (2 Cor. 4.4). “For the time past of our life may suffice us to have wrought the will of the Gentiles, when we walked in lasciviousness, lusts, excess of wine, revellings, banquetings, and abominable idolatries: 4 Wherein they think it strange that ye run not with them to the same excess of riot, speaking evil of you. (1 Pet.4:3,4)
It is true that a naive person can’t see simple dangers, but it is even more true that he can’t see the moral and spiritual implications of his actions in this world. This person will be told of the dangers but will always have an argument for why he think his desires are harmless.
Children are born in this state of naivety and it is the responsibility of parents to train them to be wise.
“Foolishness is bound in the heart of a child; But the rod of correction shall drive it far from him.” (Prov. 22:15)
Pity the child whose parents can not train him because they themselves are still naive.
There is a serious price to be paid.
Sometimes is is a personal price paid in lack of success in life, in financial troubles, or in school or a job. However, the spiritual and moral weight of this price is often seen in broken relationship, habitual sins which trap and destroy a person, or general misery as a person can never attain the peace and joy he seeks in life.
