Isaiah certainly has away with words. In the first reading for today’s Mass, Isaiah describes mountains being leveled, valleys being filled, and rough places being made smooth. It is a complete revision to the topography of the wilderness. Even in its earth-bound description, it is cosmic in its scale. Can you imagine the earth moving equipment and explosives needed to reshape this wilderness landscape?

But then again, Isaiah is not primarily talking about landscape. He is talking about the human heart. “Prepare the way of the Lord…make straight a highway…for our God.” He is admonishing us to remove anything that keeps us from seeing God’s glory. Isaiah is announcing that when God comes, nothing, not mountains, not valleys, not rugged passes, should stand between the human heart and God’s presence. Advent is the season when we hear this call anew and is our signal to let grace reshape our inner terrain.

What might all this mean for us during Advent?

“Every valley shall be filled in.” We speak of the highs and lows of life; of the hills and valleys along the way. A valley is a place where we feel spiritually or emotionally low. The place where we encounter discouragement – and often silently or alone. Perhaps it is a fear that prayers are unanswered, a sense we are failing or have failed, or a point we give up and no longer believe that change is possible. To that Isaiah proclaims: God wants to fill those valleys with hope.

Isaiah told the people of Judah and Jerusalem long ago, when the barbarians were at the walls, when the leaders had compromised faith and covenant, when hope was a dying ember that theirs was the God of Hope. The God who comforts His people lifts up the discouraged so as to remind us that He has not abandoned us, that His promises still stand, and that His coming is nearer than we think.

“Every mountain and hill shall be made low.” In our age we speak of mountains of money or we hold mountains as impenetrable fortresses where we are kept safe. But in Old Testament scripture, mountains often represent pride, self-reliance, or stubbornness—anything that rises up and blocks our view of God. Here Isaiah likely has in mind “mountains of pride.” Isaiah says these mountains must come down. Not because God wants to diminish us, but because pride blocks our sight. We cannot see the glory of the Lord when our own achievements or opinions tower in the foreground.

During Advent we might ask is our “mountain of pride” blocking our view of God or serving as a barrier to His voice? What part of our life do we insist, “I know best,” even when God is nudging us in another direction? Pride is just one mountain. Advent is a time to recognize and name your particular mountain and begin the landscaping project.

“The rugged land shall be made a plain.” Rugged, uneven ground makes walking difficult. It interrupts our pace and gait making it easy to stumble and fall. I suggest that these represent the patterns of sin, the habits we excuse, or the choices that keep tripping us up.

Advent is a season when God invites us to let grace smooth out what has become rough in us. The Sacrament of Reconciliation is one of God’s great tools for leveling uneven paths so that His coming is not hindered by obstacles we refuse to let go.

“Then the glory of the LORD shall be revealed.” Isaiah’s whole point is this: When the obstacles are removed, we see God. The glory of the Lord is not something God hides; it is something we fail to see when the terrain of our heart is cluttered or distorted. Advent reminds us God is coming. Clear the way so you can recognize Him when He arrives. Be attentive because God’s coming is not only a future event. He comes to us today in Scripture, in the Sacraments, in moments of grace, in the quiet voice of conscience. But we only perceive Him clearly when our interior landscape is open and straight and uncluttered.

Advent is not simply a countdown to Christmas. It is a spiritual landscaping project. So today, in this Eucharist, let us ask for the grace to let Him fill our valleys, lower our mountains, and smooth our rugged paths. Then we will see, not just with our eyes, but with our hearts, the glory of the Lord who comes to save us.
