Isaac Penington preaches a message of repentance and humility to the Parliament, the Army, and all the Well-affected in the Nation who have strayed from the Good Old Cause. He highlights the consequences of backsliding, including the blasphemy of God's name, the hindrance of God's work, the oppression of the innocent, and the forgetting of the sacrifices made for the Cause. Penington urges them to search their hearts, confess their sins genuinely, and turn back to God's righteous path, warning against feigned repentance and selfish interests. He calls for a true humbling before the Lord, a rejection of corrupt spirits, and a sincere commitment to the common good and righteousness, emphasizing the need to wait on the Lord for guidance and not trust in human power.

John Piper preaches on the importance of trusting in the Lord's work for those who wait for Him, emphasizing that God's labor surpasses human efforts in providing for our needs and securing our eternal good. He highlights the uniqueness, competence, and condition of God's work, stressing the necessity of seeking God's counsel, being still when He commands, and maintaining reliance on His help even in our own actions. Piper encourages the congregation to have a spirit of expectancy, knowing that God's victory is certain when we wait for Him in all circumstances.
