The first reading for Gaudete Sunday is taken from Isaiah 35: “The desert and the parched land will exult; the steppe will rejoice and bloom. They will bloom with abundant flowers, and rejoice with joyful song.” It is a message of radiant hope, but this chapter does not arise in a peaceful moment. Its beauty comes precisely because it follows a very dark and threatening context.

Isaiah 34 is a chapter of devastation and judgment carrying one of the most severe judgment oracles in the entire book. It describes:

• God’s judgment upon Edom, a symbol of all nations hostile to God.
• Land turned into a burning pitch.
• Streams turned into tar.
• A wilderness inhabited only by wild animals and demons.
• A world of chaos, desolation, and hopelessness.

Isaiah 34 begins with: “Draw near, O nations, to hear… He will hand them over to slaughter.” It ends with a picture of a land emptied and cursed. Isaiah 34 is the image of the world ruined by sin, human violence, and divine judgment.

Isaiah 35 is the surprise of reversal: hope rising from devastation. Against the backdrop of that scorched, cursed wasteland, Isaiah suddenly proclaims: “The desert and the parched land will exult; the steppe will rejoice and bloom.” This is not sentimental poetry. It is a proclamation that God’s mercy has the final word, not desolation. The land that looked dead will come back to life. People who felt abandoned will be restored. Judgment is not the end; renewal is. God transforms the desert created by human sin into a garden created by divine grace.

The historical setting is that Jerusalem and all of Judah is under the threat of Assyrian domination. Chapters 28–39 reflect the time when the Assyrian Empire is expanding southward, already having conquered the 10 northern tribes. In the south, people feel helpless, afraid, and uncertain whether God will save them. The political and religious leadership has a track record of leadership failure. As a result Jerusalem seems vulnerable and the people are disheartened and spiritually weak. Chapters 28–33 are a series of oracles of woe, warnings against foreign alliances instead of trusting in God, and rebukes for spiritual blindness of leaders and people alike. 

The crisis is quite real and existential. Assyrian invasion and victory means exile, destruction, and the end of the nation. Into this atmosphere of anxiety and judgment comes the promise of chapter 35 which mirrors the structure often seen in Isaiah: pending judgment but with the promise of hope and delivery. Isaiah 35 is a deliberate contrast to the darkness that precedes it.

Because it follows a vision of utter ruin, Isaiah 35 is proclaiming:

• God can bring joy from sorrow.
• God can create life where everything seems dead.
• No desert—literal or spiritual—is beyond God’s power to transform.
• Exile and fear will not have the last word.
• The journey home (35:8–10) is guaranteed by God’s own mercy.

Isaiah 35 is both a climax of hope after chapters of threat, and a transition toward the great consolation of Isaiah 40: “Comfort, give comfort to my people.” Against the backdrop of despair, God announces an unexpected future filled with joy, healing, return, and redemption. That is why Isaiah 35 is chosen for the Third Sunday of Advent, Gaudete Sunday: because in the middle of the darkness and weariness of life, God makes the desert bloom.
