The sermon centers on the profound humility and spiritual longing expressed in the prayer, 'That which I see not, teach thou me,' drawing from Job 34:32 and other biblical passages to emphasize the necessity of a teachable spirit in the face of divine mystery. It underscores that human understanding is limited by sin and natural blindness, and true spiritual insight comes only through the Holy Spirit's work, not human reason or self-righteousness. The preacher highlights the danger of self-deception—focusing on others' faults while remaining unaware of hidden sins—and calls believers to repentance, not merely for visible transgressions, but for secret, unacknowledged failings that corrupt the soul. Rooted in the gospel, the message affirms that salvation is complete and perfect in Christ, not earned by works, but received by faith, which is itself a gift of God. Ultimately, the sermon invites the hearer into a posture of continual dependence on God, trusting His wisdom even when unseen, and longing for the day when, face to face, we shall know Him as He is.
