The sermon, drawn from Ephesians 2:1–10, presents a profound meditation on the gospel's fullness, emphasizing that God's grace is revealed not in isolation but through the stark contrast of human sinfulness and spiritual death. It argues that the extensive, multifaceted nature of Scripture is not a burden but a divine design, intentionally revealing humanity's condition of rebellion and wrath so that the immeasurable riches of God's grace in Christ may be seen with clarity and awe. The preacher underscores that the gospel's power lies in this progression—from the dark backdrop of sin to the radiant light of redemption—illustrated through the metaphor of a diamond set against black velvet, where the full beauty of Christ's work is only appreciated in contrast to our fallen state. The passage affirms that believers are not only saved by grace through faith but are spiritually raised and seated with Christ in heavenly places, a reality that shapes present identity and future hope. Ultimately, the sermon calls the church to continual renewal, urging believers to return weekly to the Word not for novelty, but to rediscover the enduring luster of the gospel, which points forward to the eternal joy of beholding Christ face to face.
