Ecclesiastes 1:18

For in much wisdom is much grief, lack of knowledge or deliberate ignorance saving a person many a disagreeable meditation on the weakness and meanness of human nature; and he that increaseth knowledge increaseth sorrow, for he will have an understanding of conditions as they actually exist, he will be able to judge things as they are, and the realities of this world, due to sin, are always disagreeable and vexatious. It takes much trust in the Lord to overcome the offense of this world.
