God's Glory Revealed: From Covenant to Christ

Isaiah's prophecy—"the glory of the Lord shall be revealed"—unveils three essential truths about Yahweh's self-disclosure to humanity.

First, consider the doxa (glory) of the Lord itself. When Isaiah beheld the Divine vision, the seraphim sang, "Holy, holy, holy is the Lord of hosts, the whole earth is full of His glory." God has clothed Himself with light as with a garment, manifesting His glory supremely through creation and redemption. The Gospel itself bears the name euangelion (good news)—the glorious Gospel—displaying "the light of the knowledge of the glory of God in the face of Jesus Christ."

Second, observe how this glory was progressively revealed. Under the Covenant of Works, Adam and Eve's sin brought condemnation; yet mercy accompanied judgment. Yahweh promised that the seed of the woman would bruise the serpent's head. Through Abraham's covenant and David's psalms, larger discoveries of redemption unfolded across generations. The full revelation awaited the personal appearance of the Son of God.

Third, grasp the universal scope of this revelation. At Isaiah's time, darkness covered the earth. Israel's light resembled a taper in shadow. But the glory to be revealed under Christianity would shine like the sun itself—illuminating all kingdoms, nations, and languages. What once blazed within Israel's contracted space would become "a light to lighten the Gentiles, and the glory of God's people, Israel."
