A person who wants to be wise obviously must not be a person who is gullible or easily beguiled. Solomon gives us an oft repeated warning against adultery and it is clear that a literal warning is included, but that is not the main purpose of these passages.
Now the illustration is that the world will do that to us. If we will not have the Lord, if we will not listen to him, then we are subject to this world which is constantly flattering us, drawing us to itself, seeking our loyalty. On the one hand, there is the Scripture, which tells us we are members of a fallen race, we are in rebellion against God, we have no spiritual standing before him, but we are sinners in his sight, and bound for hell. Ah, but the world takes the opposite tack: ‘No you are not, do not believe that, do not believe in human depravity, do not believe in essential human badness, vulnerability, weakness, sinfulness, rottenness.’ The world believes in exalting human beings, hero worship, constantly applauding, and so on. If you go to the world and its ideology, you will not have to feel bad about yourself. On the contrary, there is now self-esteem, and self-worth, and you can feel somebody special, and indulge yourself, and your ambitions. So the world and the devil conspire to operate against you, rather like the prostitute or the adulteress, who seeks to seduce. Just as the prostitute uses skill and verbal arts to seduce, so the world has its polished and its practiced arguments, its advertisements, and its eloquence, to draw you away.
There is surely no greater handicap to any development of wisdom than a Christian who can always justify his sins. As soon as he is tempted to do something or have something, to be something which is worldly or excessive, he can always justify it. The devil can wrap him round his little finger.
