The sermon concludes a study of Ecclesiastes by focusing on the final chapter's call to remember the Creator in youth and to fear God as the ultimate duty of man. It distinguishes between the dread of the wicked and the reverential, affectionate awe that characterizes the believer's relationship with God, noting that this proper fear is the beginning of wisdom. The message emphasizes the distinction between the decaying outward man and the inward man, which is renewed day by day by the Holy Spirit, ensuring that salvation rests on God's mercy rather than human works. Through the example of Jeremiah, the sermon illustrates how God's compassions are new every morning, providing stability and strength to believers amidst life's vanities and trials. The tone is pastoral and encouraging, urging the audience to find their identity and security in the eternal work of Christ rather than in the fleeting nature of earthly existence.
