Psalm 102 opens in the dark. The servant’s days consume like smoke. His bones burn. His heart is smitten and withered like grass. His enemies reproach him all day long (Psalm 102:3–8).

The curses established in the conditional covenant at Sinai have arrived because of covenantal unfaithfulness on the part of the servant. This is what those consequences feel like from the inside.

And then the pivot every lament reaches: “But thou, O LORD, shalt endure for ever; and thy remembrance unto all generations. Thou shalt arise, and have mercy upon Zion: for the time to favour her, yea, the set time, is come” (Psalm 102:12–13).

The servant’s days are consumed. The Great King endures. His hesed outlasts the vassal’s suffering. That permanence is the covenant of grant’s answer to mortality and exile simultaneously.
