I. The Preacher commences this section by carefully defining his position and equipment as he starts on his last course. (1) His first conclusion is that wisdom, which of all temporal goods still stands foremost with him, is incapable of yielding a true content. Much as it can do for man, it cannot solve the moral problems which daily task and afflict his heart, the problems which he must solve before he can be at peace (8:16-9:6). (2) He reviews the pretensions of Wisdom and mirth (Ecclesiastes 9:7-10). To the baffled and hopeless devotee of wisdom he says, "Go, then, eat thy bread with gladness, and drink thy wine with a cheerful heart. Whatever you can get, get; whatever you can do, do. You are on your road to the dark, dismal grave, where there is no work nor device; there is the more reason therefore why your journey should be a merry one." (3) He shows that the true good is not to be found in devotion to affairs and its rewards (9:13-10:20).
II. What the good is, and where it may be found, the Preacher now proceeds to show. (1) The first characteristic of the man who is likely to achieve the quest of the chief good is the charity which prompts him to be gracious, and show kindness, and do good, even to the thankless and ungracious. (2) The second characteristic is the steadfast industry which turns all seasons to account. Diligent and undismayed, he goes on his way, giving himself heartily to the present duty, "sowing his seed, morning and evening, although he cannot tell which shall prosper, this or that, or whether both shall prove good." (3) This man has learned one or two of the profoundest secrets of wisdom. He has learned that giving, we gain; and spending, thrive. He has also learned that a man's true care is himself; that his true business in the world is to cultivate a strong, dutiful character which shall prepare him for any world or any fate. He recognises the claims of duty and of charity, and does not reject these for pleasure. These keep his pleasures sweet and wholesome, prevent them from usurping the whole man and landing him in the weariness and satiety of disappointment. But lest even these safeguards should prove insufficient, he has also this: he knows that "God will bring him into judgment;" that all his work, whether of charity, or duty, or recreation, will be weighed in the balance of Divine justice (Ecclesiastes 9:9). This is the simple secret of the pure heart the heart that is kept pure amid all labours, and cares, and joys.
