More Denial or More Wisdom?

 "To drive well, you have to keep your eyes skinned to notice exactly what it is in front of you. To live wisely, you have to be clear-sighted and realistic–ruthlessly so–in looking at life as it is. Wisdom will not go with comforting illusions, false sentiment, or the use of rose-coloured spectacles. Most of us live in a dream world, with our heads in the clouds and our feet off the ground; we never see the world, and our lives in it, as they really are. This deep-seated, sin-bred unrealism is one reason why there is so little wisdom among us–even the soundest and most orthodox of us. It takes more than sound doctrine to cure us of unrealism. There is, however, one book in Scripture that is expressly designed to turn us into realist: and that is the book of Ecclesiastes." (J.I. Packer, Knowing God: God's Wisdom and Ours, pg. 93)
