In the life-study of Job, Proverbs, Ecclesiastes and Song of Songs, Witness Lee presents not only the subject, general sketch, and central thought of each book but also leads the reader into the emphasis of each book according to God's economy. He shows that the book of Job emphasizes that God wants man to seek and gain God solely without any other blessings and prosperity, and that God wants man to seek Him for his perfection and not for his integrity. From this we see that God wants man to seek the kind of perfection that is God Himself, not a perfection based on human uprightness and integrity. The book of Proverbs stresses wisdom that man receives of God through his contacting of God and that teaches man how to behave in his human life. Ecclesiastes stresses the vanity of vanities of all the things under the sun, which is realized by man through the wisdom received from God. The things under the sun are vanity, but the things in the heavens are reality. Song of Songs stresses that Christ is the song of songs, the satisfaction of satisfactions to human life that is versus the vanity of vanities of all the things under the sun. Only Christ is the satisfaction, becoming our song which we sing to Him because we are satisfied. A lover of Christ should be one who is attracted by His love and drawn by Him in His sweetness to pursue after Him for full satisfaction.
