As Advent begins, the Church invites us to wait with expectant hope—not passively, but actively. The scripture reading for first Sunday of advent highlights God’s light breaking into darkness, God’s path being made ready, and God’s people being called to wake up and live differently. Isaiah paints a vivid picture: those who walked in darkness receive a great light, joy rooted in God’s presence. Luke then lifts our eyes to the message of preparation, where valleys are filled and crooked ways are made straight. Finally, Romans translates the season into daily discipleship: it is time to cast off the works of darkness and put on the Lord Jesus Christ. These passages work together like a lantern—revealing where we are, where God is taking us, and what we can begin doing today.

Bible Verses

1) Begin Advent with God’s light in the middle of darkness

First Sunday of Advent often feels like stepping into a long hallway of waiting. But the waiting is not empty—God is coming, and the Scriptures give us a clear first picture. Isaiah 9:2-3 speaks to people who were “walking in darkness” and dwelling “in the land of the shadow of death.” Advent doesn’t deny darkness; it names it. Yet it refuses to let darkness have the final word.

Isaiah says, “they… have seen a great light.” That phrase matters because it moves hope from wishful thinking to divine visitation. Advent is not only about remembering God’s past faithfulness; it is also about receiving God’s present light. When Isaiah continues with joy—joy “before thee” like harvest joy and like the rejoicing of those who divide the spoil—he’s describing a kind of happiness that isn’t fragile or dependent on everything being perfect. It’s anchored in God’s coming.

This is why Isaiah is a strong starting point for Advent first Sunday scripture reading. It prepares your heart to expect illumination. If you are weary, Isaiah teaches you to look for the “great light.” If you are grieving, Isaiah invites you to trust that joy can still be multiplied by God’s presence.

Advent also asks for response: when light comes, darkness loses its authority. Isaiah quietly sets the stage for what Romans will later make explicit—putting on light rather than remaining in darkness.

2) Prepare the way: valleys filled, crooked ways made straight

Luke 3:4-6 brings Advent preparation into focus with striking imagery. The text is a quotation about a “voice of one crying in the wilderness,” calling people to “Prepare ye the way of the Lord, make his paths straight.” This is not preparation as mere ritual. It is preparation as alignment—life straightened toward God.

Luke’s description continues with leveling and smoothing: “Every valley shall be filled, and every mountain and hill shall be brought low.” Valleys represent low places—places of discouragement, limitation, or spiritual weariness. Mountains and hills represent obstacles—pride, hard habits, or whatever keeps you from walking with God. Advent is God’s promise that what’s low will be lifted and what’s high will be brought down.

Then Luke speaks to the crooked and the rough: “the crooked shall be made straight, and the rough ways shall be made smooth.” These words are intensely practical. They describe a heart that has wandered from God and a life that feels uneven or resistant. Advent calls you to bring the crookedness and roughness into the light of God’s transforming work.

Finally, Luke offers the reason: “And all flesh shall see the salvation of God.” Advent preparation is ultimately relational and salvific. The goal isn’t just better behavior; it’s that people—“all flesh”—can see God’s salvation.

When you read Luke after Isaiah, the connection becomes clear. Isaiah gives the light; Luke shows the path. And that path is meant to lead you to salvation. This is why these readings function well together as scripture passages for the first Sunday of Advent—they move from illumination (Isaiah) to preparation (Luke).

3) Wake up and live like you belong to the day

Romans 13:11-14 turns Advent imagery into lived obedience. Paul begins with urgency and hope: “knowing the time, that now it is high time to awake out of sleep.” Advent is, in a sense, a spiritual wake-up call. Not because God is disappointed in us, but because God is near.

Paul continues with a rhythm: “for now is our salvation nearer than when we believed.” That statement is the heart of Advent waiting. Salvation is not far away in the future only; it is “nearer” because God is moving. The season teaches us to read time differently—less as drift, more as approach.

Then Paul lays out a contrast that fits the themes of Isaiah and Luke: “The night is far spent, the day is at hand.” If Isaiah celebrates a great light, and Luke calls for paths being made ready, Romans tells you what that means day-to-day. It’s time to respond by casting off darkness: “let us therefore cast off the works of darkness, and let us put on the armour of light.”

Paul also gives tangible examples: “Let us walk honestly… not in rioting and drunkenness, not in chambering and wantonness, not in strife and envying.” These aren’t merely “rules”; they describe the shape of a life that belongs to the light.

Then comes the centerpiece: “But put ye on the Lord Jesus Christ, and make not provision for the flesh, to fulfil the lusts thereof.” Advent preparation becomes spiritual clothing. You don’t just admire Christ—you receive Him and let Him form your choices.

So in your reading for the first day of Advent, Romans teaches you to translate the season into daily repentance and renewal: awake, cast off, and put on Christ.
