Horatius Bonar emphasizes the necessity of true consolation in times of trouble, as exemplified by Job's suffering. He identifies the conditions under which consolation can be effective, including the state of mind of the sufferer, the integrity of the comforter, and the nature of the consolation offered. Bonar warns against false forms of consolation, such as sentimentalism, appeals to self-love, fatalism, and pleasure-seeking, which ultimately fail to provide real comfort. He asserts that true consolation is rooted in truth, particularly the truth of God's character and His purposes in our suffering. The sermon concludes that only the truth of Scripture and the presence of Christ can provide genuine comfort and healing.
