H. P. Barker emphasizes the importance of remembering the Lord Jesus Christ and not forgetting His sacrifice and love. He draws parallels between the forgetfulness of humans towards each other, like the late Queen of the Belgians, and the forgetfulness of the chief butler towards Joseph in the Bible. Barker highlights the significance of partaking in the Lord's supper as a way to cherish and remember Christ, rather than focusing solely on personal blessings or benefits received.

H. P. Barker preaches about the cautionary tale of Jethro, Moses' father-in-law, who despite his good qualities and wise counsel, failed to fully identify with the people of God and embrace God's purpose for His chosen ones. Jethro rejoiced in God's goodness towards Israel, offered wise advice to Moses, and showed kindness to his family, yet he chose to return to his own land instead of fully engaging with God's people. Similarly, many today may have admirable qualities but fall short of fully understanding and embracing their heavenly calling as Christians, missing out on the richness of God's purpose and the reproach of Christ.

H. P. Barker preaches about the significance of the Holy Spirit as the 'earnest' given to believers, providing comfort, assurance, and a foretaste of our heavenly inheritance. Using the analogy of a telescope given to a boy on a voyage, the Holy Spirit grants believers a clearer spiritual vision of the eternal promises awaiting them. Just as a farmer prepares a field of clover for his sheep, the Holy Spirit prepares believers for their heavenly home by allowing them to experience glimpses of their future inheritance now.

H. P. Barker delivers a sermon on the importance of examining our motives in our actions and service to God. Using the story of the architect Cnidius who sought fame by subtly inscribing his name on a tower meant to warn mariners, Barker highlights the significance of pure motives in the eyes of God. He emphasizes that at the judgment seat of Christ, our motives will be weighed heavily, and the quality of our works will be evaluated based on the purity of our intentions, not just the quantity of our deeds.

H. P. Barker preaches on the assurance that believers are kept by the power of God, emphasizing the need to trust in God's strength to uphold us in times of temptation and weakness. He highlights the importance of faith as the means through which God sustains us, drawing parallels to a miller filling a sack with flour to make it stand. Barker also discusses how God uses trials and adversity to strengthen and support us, likening it to making an egg stand on its end by creating a dent through a hard knock.
