John Nelson Darby explores the narrative of Balaam and Balak, emphasizing how God's sovereignty turns the wicked intentions of Balaam into a means of blessing for Israel. Despite Balaam's wickedness and attempts to curse God's people, he ultimately can only speak the blessings that God puts in his mouth, showcasing the confusion between human will and divine purpose. The sermon highlights the distinction between God's judgment of His people and their moral failures, affirming that believers are justified through Christ, regardless of their shortcomings. Darby encourages the congregation to recognize their identity as God's peculiar people, blessed and protected under His care, and to find peace in their standing before Him. The overarching message is that God's power prevails over the schemes of evil, revealing the beauty and strength of His people.
