In Our Sanctuary, Spurgeon proclaims that God Himself—not temple, ritual, nor place—is the believer's refuge and dwelling. He unfolds Jeremiah's declaration that "A glorious high throne from the beginning is the place of our sanctuary", showing God as sovereign, eternal, and reigning with justice, power, and love. Spurgeon contrasts the safety of God's throne with the peril of forsaking Him, warning that those who depart "shall be ashamed" and "written in the earth". He urges hearers to flee to God as their only true sanctuary—refuge from guilt, temptation, sorrow, and the thirst of the soul that no earthly cistern can satisfy.

This sermon is narrated by Alexander Scourby, whom the Chicago Tribune hailed as possessing "the greatest voice ever recorded." His narration gives Sermon 1786 a living pulse. Scourby's resonance deepens Spurgeon's appeals, his clarity sharpens each doctrinal line, and his steady cadence carries the emotional weight of divine sovereignty and mercy with uncommon authority. The sermon's imagery—God's throne, the fountain of living waters, the danger of forsaking Him—becomes vivid and immediate. Scourby adds gravity, warmth, and spiritual presence, transforming Spurgeon's written words into an experience that feels spoken directly to the heart, restoring their timeless power with unmatched immediacy.
