The Secret of Life

Ecclesiastes 12:9-14

9 Besides being wise, the Preacher also taught the people knowledge, weighing and studying and arranging many proverbs with great care. 10 The Preacher sought to find words of delight, and uprightly he wrote words of truth.
11 The words of the wise are like goads, and like nails firmly fixed are the collected sayings; they are given by one Shepherd. 12 My son, beware of anything beyond these. Of making many books there is no end, and much study is a weariness of the flesh.
13 And I applied my heart to seek and to search out by wisdom all that is done under heaven. It is an unhappy business that God has given to the children of man to be busy with. 14 I have seen everything that is done under the sun, and behold, all is vanity and a striving after wind.
