Ec 1:16 I communed with mine own heart, saying, Lo, I am come to great estate, and have gotten more wisdom than all they that have been before me in Jerusalem: yea, my heart had great experience of wisdom and knowledge. 17 And I gave my heart to know wisdom, and to know madness and folly: I perceived that this also is vexation of spirit. 18 For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.

Solomon made a great mistake here in his own life. Instead of examining his life from God's prospective, he examined it from a fleshly perspective. He became proud in his wisdom, rather than humble that it was given from God. Instead of searching out the things of God by wisdom, he choose to search out the things of the world, to know madness and folly, as if he because God had given him wisdom would be able to handle these things without them harming him. He fell victim to the same folly that others do because as he pointed out in Pr 6:27 Can a man take fire in his bosom, and his clothes not be burned?.

Knowing God's Word, and thereby God's wisdom does not keep the consequences of sin from occurring if you meddle with foolishness. Instead Solomon found sorrow and pain. Trying to mix the Bible and the World is like mixing oil and water, the two don't go together. The reason Solomon says that in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow is because once you know the things of God, your conscience accuses you when you meddle in the things of this world. Solomon knew that the things that he was doing were wrong, and he knew that the consequences would be bad, yet he did them anyway. His wisdom told him that he would be sorrowful and it was right. The admonition in this is not avoid wisdom and knowledge, it is be faithful in the wisdom and knowledge that you have or you will produce sorrow in your life.
