Saying Yes Will Cost You Something: A Luke 1 Devotional on Costly Obedience

Saying yes to God is rarely free—but it is always purposeful. In Luke 1:38, Mary’s obedience reminds us that faith often comes with a cost, yet God never calls us forward without promising His presence. This devotional invites you to reflect on what obedience may require—and why it is worth trusting God with the cost.

This devotional series is part of our ongoing Luke Discipleship Journey, exploring how following Jesus shapes obedience, surrender, and daily faith.

Costly Obedience

Day 5: Saying Yes Will Cost You Something

Scripture: Luke 1:38 (NIV)
Focus: Costly Obedience

Mary’s yes was not a quiet, comfortable decision.

When she said, “I am the Lord’s servant… May your word to me be fulfilled,” she wasn’t stepping into applause or approval. She was stepping into misunderstanding, judgment, and uncertainty.

Her obedience would cost her reputation.
It would cost her comfort.
It would cost her control over how her life would unfold.

And yet—she said yes.

Luke doesn’t tell us that God explained the social cost. He didn’t outline the whispers, the suspicion, or the emotional weight Mary would carry. Instead, God promised His presence.

That tells us something important about discipleship.

Obedience Always Has a Cost

We often celebrate obedience after the outcome becomes beautiful. But in the moment, obedience can feel heavy.

Mary’s yes meant being misunderstood by her community. It meant risking rejection. It meant trusting God with her future when the present felt fragile.

This is where faith becomes real.

Discipleship is not free of cost—but it is full of purpose.

Jesus never promised that following Him would be easy. He promised that it would be worth it.

The Enthymeme of Costly Faith

Many believers carry this unspoken reasoning in their hearts:

“I think I can follow God… as long as it doesn’t cost me too much.”

But Scripture gently challenges that assumption:

If obedience costs nothing, then surrender hasn’t truly happened.
But if obedience costs something precious, then trust has taken root.

Christianity without cost is not the Christianity Jesus preached.

He spoke openly about taking up the cross—not as punishment, but as transformation.

God Promises Presence, Not Convenience

When we read the story of Mary’s calling, it is easy to focus on the beauty and wonder of the moment. An angel appears. A miraculous promise is spoken. A young woman becomes part of God’s redemptive story in a way that will change the course of history. But if we look closely at what actually unfolds in her life, we begin to see something important about how God works.

Notice what God did not promise Mary.

He did not promise that the path ahead would be easy. He did not promise that everyone around her would immediately understand what was happening. He did not promise that her obedience would protect her from emotional difficulty or personal cost.

In fact, Mary’s journey would include moments that were deeply challenging.

People in her community could easily misunderstand her situation. The explanation she carried—that her pregnancy was the result of divine intervention—would not be simple for others to accept. There would be uncertainty, questions, and the quiet pressure of living with a story that few could fully comprehend.

God also did not promise her a life free from pain. Years later, she would stand near a cross and watch her son suffer in a way no parent ever wishes to witness. The same child who was announced with heavenly joy would eventually carry the weight of humanity’s brokenness.

Yet in the middle of all those realities, God offered something more profound than convenience.

He promised His presence.

This promise appears throughout Scripture again and again. When God calls people into His purposes, He does not always outline every detail of the journey ahead. He rarely removes every challenge that might arise along the way. Instead, He offers something far more sustaining: the assurance that we will not walk the path alone.

Presence often carries more strength than explanation.

Human beings naturally want clarity. When we face uncertain situations, our instinct is to ask why. We want to understand the reasons behind events and the direction our lives are taking. Explanations can feel comforting because they give us a sense of control over what we are experiencing.

But life rarely provides complete explanations.

There are moments when circumstances unfold in ways that we cannot fully understand. Questions remain unanswered, and the future appears unclear. In those moments, information alone would not be enough to steady the heart.

What we truly need is presence.

When someone walks beside us during a difficult season, the experience changes. The problem may still exist, but the loneliness surrounding it begins to fade. The simple reality of not facing the journey alone brings a quiet strength that explanation cannot always provide.

God’s promise of presence works in a similar way.

Instead of offering a detailed roadmap for every step of the journey, He assures us that He will remain with us throughout it. His presence becomes the anchor that holds our hearts steady even when the path ahead feels uncertain.

This truth also reshapes the way we understand obedience.

Many people assume that obedience to God should lead to a life of constant comfort. If we follow His guidance faithfully, we sometimes expect that difficulties will disappear or that circumstances will unfold smoothly. When challenges arise, it can feel confusing because it seems to contradict those expectations.

But Scripture consistently shows a different pattern.

God does not always remove the cost of obedience.

Following His call sometimes requires courage. It may involve stepping into situations that feel unfamiliar, trusting His guidance when outcomes are not yet visible, or continuing forward even when others do not fully understand the journey.

Mary experienced this firsthand. Her yes to God opened the door to extraordinary purpose, but it also required trust through seasons of uncertainty.

The beauty of her story is not that the path became effortless. The beauty is that God remained faithful within the process.

And that same promise extends to us.

When we choose to trust God, we are not guaranteed a life without challenges. There may still be moments when the road feels difficult or when answers take longer to appear than we hoped.

Yet the promise of His presence transforms how we walk through those moments.

It reminds us that we are not navigating life’s complexities by our own strength alone. God’s presence provides guidance when decisions feel uncertain. It offers comfort when circumstances are painful. It brings peace that steadies the heart when anxiety begins to rise.

Presence also deepens relationship.

When God walks with us through real experiences—through joy, uncertainty, waiting, and growth—our understanding of Him becomes more personal. Faith moves beyond abstract ideas and becomes a lived relationship with the One who is actively involved in our lives.

Over time, this relationship becomes the foundation of trust.

We begin to realize that even when explanations are incomplete, His character remains reliable. His wisdom extends beyond our understanding, and His presence provides the strength we need for each step of the journey.

In the end, convenience may make life easier for a moment, but presence sustains us for a lifetime.

God’s promise to walk with us is not a small assurance. It is one of the most powerful gifts He offers. It means that wherever obedience leads—through celebration, uncertainty, growth, or challenge—we are never abandoned along the way.

He does not simply send us forward with instructions.

He walks with us through the path itself.

When Yes Feels Risky

“God often calls ordinary people to costly obedience, not comfortable faith.”

Saying yes to God can sometimes feel like stepping into the unknown. It sounds simple when spoken in a sentence—“Just trust God.” But in real life, that trust often asks us to release something we have been holding tightly.

At the heart of obedience is the willingness to surrender control.

Most of us naturally prefer certainty. We like to see the path ahead, to know how our decisions will unfold, and to feel confident that our plans will work the way we imagined. Control provides a sense of security. It allows us to organize life in ways that feel predictable and safe.

But when God invites us to trust Him more deeply, that sense of control is often the very thing He asks us to release.

And that can feel risky.

Obedience may lead you into places you did not originally plan. It may stretch your comfort zone and challenge assumptions you once held about how your life would unfold. The invitation to follow God’s direction sometimes requires a shift that feels both exciting and unsettling at the same time.

There are moments when saying yes to God means letting go of comforts you have grown used to.

Comfort is not inherently wrong. In fact, stability and peace can be beautiful gifts from God. Yet comfort can also become a place where growth slows if we become too attached to familiarity. When God calls us into something new, He may invite us to step beyond what feels predictable so that we can experience deeper trust in Him.

Obedience may also cost the approval we have relied on.

Human approval can quietly shape our decisions. We naturally want to be understood and affirmed by the people around us. When those voices support our choices, it feels reassuring. But there are times when following God’s direction leads us in ways that others may not immediately understand.

Their confusion or disagreement can make obedience feel lonely.

In those moments, faith asks a gentle but important question: whose voice carries the greatest influence in your life?

Choosing God’s guidance over human approval is rarely easy, yet it often becomes one of the most defining moments of spiritual growth.

Obedience can also require releasing plans you carefully arranged.

Many people approach life with thoughtful preparation. Goals are set, timelines are created, and steps are mapped out in order to move toward a desired future. Planning itself is wise and responsible. But even the best plans sometimes need to be surrendered when God begins to lead in a different direction.

That shift can feel disorienting.

The plans we made may have represented years of thought, effort, and hope. Letting go of them can feel like stepping away from something deeply personal. Yet God often sees a larger picture than we can see in the present moment.

What appears to be a disruption may actually be a redirection.

Sometimes obedience also affects relationships.

When God leads you toward certain decisions or changes, the people around you may not immediately understand why. They may question your choices or worry about the path you are taking. In some cases, relationships that once felt aligned may begin to feel strained.

This can be one of the most difficult parts of obedience.

We naturally value connection and shared understanding. When others struggle to see the reasons behind our decisions, it can feel isolating. Yet throughout Scripture and history, many people who followed God’s call walked through seasons where their choices were misunderstood.

Faith does not guarantee that every relationship will immediately affirm your obedience.

But it does remind us that God sees the sincerity of a surrendered heart.

And this leads to an important truth: God never wastes a surrendered yes.

Even when obedience feels costly in the moment, God has a way of weaving those decisions into a larger story. The sacrifices we make today often become the very experiences that shape our character, deepen our faith, and prepare us for the future He is unfolding.

What feels like loss in one season often becomes testimony in another.

The comfort you released may become the doorway to growth you could not have experienced otherwise. The approval you surrendered may strengthen your confidence in God’s voice rather than in the opinions of others. The plans you laid down may lead you toward opportunities that were never visible from your original path.

Even the relationships that struggled to understand your obedience may eventually witness the fruit that grows from it.

Over time, the story begins to change.

Moments that once felt uncertain begin to reveal meaning. Decisions that seemed risky begin to show evidence of God’s guidance. What once appeared to be sacrifice becomes a testimony of how God worked through your willingness to trust Him.

This does not mean every step will feel easy.

Obedience still requires courage. It still invites patience when outcomes take time to unfold. Yet the assurance that God values every surrendered yes provides the confidence needed to keep moving forward.

Because in God’s hands, nothing offered in trust is ever wasted.

Each act of surrender becomes part of a larger story—a story where faith grows stronger, purpose becomes clearer, and the life that once felt uncertain begins to reveal the quiet faithfulness of the God who was guiding it all along.

Obedience Shapes Who We Become

Mary’s yes didn’t just change her circumstances—it shaped her character.

Through her obedience, she learned to trust God beyond logic. She learned to lean on God’s faithfulness rather than public opinion.

The cost of obedience often becomes the soil where faith grows deepest.

And here’s a quiet truth we don’t always say out loud:

The things obedience costs us are often the very things that once held us back.

Pause and Reflect

Take a moment here—not to rush ahead, but to be honest with God.

What might obedience cost me—and am I willing to trust God with that cost?

This question isn’t meant to pressure you. It’s meant to free you.

Because God never asks for surrender without purpose.

Costly Obedience Produces Lasting Fruit

“Faithfulness sometimes means obeying God without immediate reward or recognition.”

Mary didn’t know how her story would unfold—but her obedience changed history.

Your obedience may not feel dramatic. It may look quiet. It may feel unseen.

But every yes to God carries eternal weight.

God measures faithfulness differently than the world does. He values trust over comfort, obedience over applause, surrender over security.

And He honors every step taken in faith.

When Fear Whispers “Don’t”

Fear will always highlight the cost before it shows the purpose.

It will say:

“You’ll lose too much.”
“People won’t understand.”
“What if this doesn’t work out?”

But faith listens for a different voice—the steady assurance of God’s presence.

God never calls us forward without walking with us.

Reflection

Sit with these questions today:

What comfort might God be asking me to release?
Where have I delayed obedience because of fear of loss?
How might trusting God with the cost deepen my faith?

Let these questions draw you closer to God, not away from Him.

A Prayer of Surrender

“Lord, I surrender my comfort for Your calling.
I trust You with what obedience may cost me.
Give me courage to say yes, even when it feels risky.
Walk with me as I follow You.
Amen.”

A Call to Action

Today, choose obedience in one tangible way.

Not because it feels easy—but because God is worthy of your trust.

Faith grows when we act on it.

Say yes again—this time with open hands.

Questions to Carry With You

What would my faith look like if I trusted God with the cost?
Where might God be asking me to choose obedience over comfort?
If Mary’s yes changed history, what might God do with mine?

Stay with those questions.

God still works through surrendered hearts.
And every costly yes makes room for His purpose to unfold.

You may not see the full picture yet—but God is already at work.

Your yes matters more than you know.
