G. Campbell Morgan emphasizes the profound messages found in the book of Joel, illustrating the principles of Divine government and grace through the prophet's visions of locust plagues, imminent judgment, and the future outpouring of the Spirit. He highlights that the 'Day of the Lord' is both a present reality and a future promise, urging repentance and recognition of God's active governance in all circumstances. Morgan calls for believers to proclaim the fullness of the Spirit and to encourage others to call on the name of the Lord for salvation, reminding them of God's grace amidst judgment.

John Nelson Darby discusses the foundational themes of 1 Peter 1, emphasizing that Peter addresses the Jewish Christians scattered throughout the world, focusing on their redemption and the divine government of God. He explains that while the first epistle lays the groundwork of redemption, it also prepares the saints for suffering and the principles of God's governance, contrasting it with the second epistle which addresses the wicked. Darby highlights the importance of understanding the relationship between the church and the house of God, noting that Peter's teachings are distinct from Paul's emphasis on the body of Christ. He also touches on the significance of being elect according to God's foreknowledge and the role of the Holy Spirit in sanctification and obedience.
