A.W. Tozer warns of the dire consequences of unavailing prayers during the Day of the Lord, as depicted in Revelation. He emphasizes that cries for mercy will come too late for those who have relied on human strength rather than on God. The sermon highlights the certainty of God's judgment and the futility of seeking refuge in earthly things when faced with divine wrath. Tozer calls for a recognition of the urgency to turn to Christ before it is too late, as the earth will be shaken and given to Jesus, the Worthy One.

Al Whittinghill emphasizes the urgent need for prayer within the church, highlighting the significance of a Solemn Assembly as a time for believers to come together, set aside personal agendas, and seek God's heart for revival. He reflects on the early church's commitment to prayer and how it was the foundation for their growth and impact, urging the congregation to prioritize prayer as the essential work of the church. Whittinghill calls for a collective response to God's call, encouraging everyone to participate in prayer meetings and to recognize the power of corporate prayer in overcoming challenges and fulfilling God's purposes.
