The Bible makes sense of the world outside of us—and the world inside of us.

It tells the truth about what we can see: our relationships, our habits, our neighborhoods, our work, our pressures, our temptations. And it tells the truth about what we often can’t see clearly: our motives, our desires, our restlessness, our pride, our envy, our self-justifying stories. The Scriptures interpret our lives with a severe mercy—refusing to flatter us, and refusing to leave us without hope.

That is why Galatians remains such a needed letter for the church. It is fierce, but it is healing. It is sharp, but it is tender. It is about the ever-present human impulse to drift away from Christ as the source—and to rebuild our confidence somewhere else.

A simple summary of the message of Galatians might be this often used phrase:

We are saved by faith alone—but not by a faith that is alone.

Paul fights for justification by faith with a holy stubbornness. But he also insists that saving faith is living faith that produces a new kind of person. That is where our devotional focus lands today: life in the Spirit, or in Paul’s words, “keeping in step with the Spirit.”

The main text

Galatians 5:25–26 (ESV) — “If we live by the Spirit, let us also keep in step with the Spirit. Let us not become conceited, provoking one another, envying one another.”

If we live by the Spirit—if our life is sourced in Him, given by Him, sustained by Him—then we must also walk by the Spirit. The Christian life is not only a miracle that happens to us; it is a path we walk.

And notice where Paul goes immediately: not to private mystical experiences, but to relationships. “Let us not become conceited, provoking one another, envying one another.” When we step out of sync with the Spirit, one of the first places it shows up is the way we treat people.

So how do we keep in step with the Spirit?

To answer that, it helps to ask a deeper question: Who is the Spirit to Paul? Not as an abstract doctrine, but as the living, personal God at work in the Christian.

The Spirit in Paul’s greeting

At first glance, Paul’s greeting to the Galatians sounds like it highlights the Father and the Son.

Galatians 1:3–5 (ESV) — “Grace to you and peace from God our Father and the Lord Jesus Christ, who gave himself for our sins to deliver us from the present evil age…”

You might ask: Where is the Holy Spirit in that greeting?

The Spirit is not absent at all—because the Spirit is the One who personally brings and applies “grace and peace” to us. The Father plans salvation. The Son accomplishes salvation. The Spirit applies salvation—making it real in us, not merely true in principle.

That means the fruit of the Spirit is not a detached moral “to-do list.” It is a description of what God Himself produces in a person when He takes up residence there. When love grows in you, that is not merely “you trying harder.” It is Christ in you by His Spirit. When joy grows, it is Christ in you. Peace, patience, kindness—these are not simply traits; they are evidences of a new life.

Something is being renovated. A new birth. New desires. A new appetite.

The war inside: Spirit against flesh

Paul says it plainly:

Galatians 5:17 (ESV) — “For the desires of the flesh are against the Spirit, and the desires of the Spirit are against the flesh…”

So if you are a Christian, you should not be surprised that you experience conflict. You should not interpret every struggle as hypocrisy. Some struggles are the very evidence that a deeper work is happening.

J.C. Ryle captured this tension by saying: “a true Christian is marked not only by peacewith God, but also by war within. Not war that excuses sin, but war that refuses to make peace with it”

And C.S. Lewis echoes the same when he says, “religious feelings can be deceptive. You can feel stirred, enlightened, even moved—while your actual conduct remains unchanged. In other words, “feeling better” is not the same thing as actually becoming healthier.”

So the Spirit changes our appetite. He doesn’t merely adjust our emotions; He redirects our desires. He doesn’t merely inform our minds; He reforms our lives.

But this raises a crucial pastoral concern:

If we emphasize “walking,” “battle,” and “fruit,” will people start thinking we are earning our salvation?

Paul would say: only if you confuse justification and sanctification.

Justification and sanctification: don’t confuse the gifts

We need clarity here, because confusion here creates either pride or despair.

Ryle helpfully distinguished these two realities (and we can summarize his points in plain language):

• Justification is God’s legal declaration about you: because of Christ, you are counted righteous—fully, freely, finally.

• Sanctification is God’s transforming work in you: by the Spirit, you are actually being made holy—truly, gradually, imperfectly in this life, but really.

Justification is complete the moment you believe. Sanctification is progressive for as long as you live.

Justification is the basis of your acceptance. Sanctification is the evidence of your renewal.

And the relationship between them matters. Where there is no sanctification, there is no justification. Not because sanctification earns justification, but because the Christ who justifies also sanctifies. Sanctification is never the basis of acceptance—Christ alone is, but it is the inevitable fruit of the faith that justifies.The Spirit who gives life also produces that fruit. A tree that is alive bears fruit—not to become alive, but because it is alive.

A simple illustration helps:

Justification is like a prisoner receiving a full pardon.
Sanctification is that pardoned prisoner learning to live as a free and useful citizen.

The pardon is not earned by the productivity. But productivity will follow true freedom.

So what would it look like to go into battle knowing you will win?

That is the Christian position. The outcome is not in doubt because Christ has already triumphed. But if you refuse to suit up, if you refuse to fight, you will be battered—not because Christ is weak, but because you are trying to live as if the war is optional.

Keeping in step with the Spirit means we fight from victory, not for victory.

A note on assurance: the Spirit as down payment

Sometimes Christians hear “sanctification” and immediately assume God is perpetually disappointed in them, and their assurance begins to leak away. But Paul would say the opposite: the Spirit’s presence is meant to strengthen assurance, not weaken it.

Ephesians 1:13–14 (ESV) — “…you were sealed with the promised Holy Spirit, who is the guarantee of our inheritance…”

The Spirit is the “down payment” of what is coming. He is God’s pledge that He will finish what He started. So when you see real fruit (however small) do not despise it. It is evidence that God is at work. And when you see real sin, do not pretend it is harmless. Take it to war, because you belong to Christ.

And that brings us back to Galatians:

“If we live by the Spirit, let us also keep in step with the Spirit.”

So what does that look like in practice?

Practically keeping in step with the Spirit

Here are ten guiding principles meant to help us keep in step with the Spirit.

1) Use Scriptural means, not imaginary shortcuts

God grows His people through ordinary channels: Bible reading, prayer, public worship, the Lord’s Supper.
We often look for a hidden lever—some secret trick. But the Lord feeds His people the way He always has: with Word and Sacrament and prayer, in the fellowship of the saints. There is no need to invent a new kind of nutrition when bread still nourishes.

2) Remember where you’re headed

Heaven is not merely “rest.” It is a holy rest. Many want forgiveness, but do not consider whether they actually want holiness. The Spirit prepares us not only to enterheaven, but to enjoy heaven. Strive for holiness, without which we will not see the Lord (Heb. 12:14).

3) Don’t retreat from the world

The Spirit does not turn Christians into spiritual cave-dwellers. He makes us salt and light in real callings: parent, child, employer, employee, neighbor, church member. If your spirituality is producing habitual isolation, simmering resentment, or a constant desire to withdraw from people, that is not the Spirit’s pattern. The fruit of the Spirit is profoundly relational.

Fruit is grown to be eaten, not displayed. People around you are starving for love, joy, peace, patience. God often intends to feed them through your ordinary presence.

4) Obey decisively

Do not wait for perfect desire before you act. Sometimes obedience is the path todesire. Like running: you may want to be healthy and have no desire to run. But as you begin, desire often follows. In the Christian life, obedience can be the seedbed where new affections grow. What has God called you to do? Take up and follow.

5) Act like Jesus in tangible ways

Sanctification is not merely avoiding badness; it is learning active goodness—kindness, generosity, self-denial, practical help. The Spirit conforms us to Christ, not only in what we refuse, but in what we pursue. Following Christ is not a drag, but a light burden, enjoying the Bread of life, and days filled under the steady hand of God’s sovereign mercy.

6) Take every thought captive

2 Corinthians 10:5 (ESV) — “…take every thought captive to obey Christ.”
And:
Romans 8:5–6 (ESV) — to set the mind on the Spirit is life and peace.

Repentance is not only turning from actions; it is turning from thought-patterns—arguments, assumptions, mental habits that raise themselves against the knowledge of God, too. As earlier noted: the first degree of holiness is often the decisiveness of repentance.

7) Let the Spirit send you humbly to Christ

Walking in the Spirit does not produce a self-made identity. It produces a Christ-held identity. And it teaches us a crucial humility: the Bible does not train us first to see ourselves as victims seeking vindication, but as sinners needing mercy—whatever our circumstances may be. The Spirit makes us honest, because we are finally safe in Christ. All is made well and all is ok.

8) Expect holiness to grow into happiness

Holiness is not misery. Over time, it becomes a deep happiness the world cannot manufacture. Not a shallow cheerfulness, but a settled peace, a steady conscience, a lighter yoke. The Spirit is not leading you into gloom; He is leading you into freedom.

9) Remember the cross: your past has been crucified

Galatians 5:24 (ESV) — “…have crucified the flesh with its passions and desires.”
Galatians 2:20 (ESV) — “I have been crucified with Christ…”

Keeping in step with the Spirit includes holy memory: you are not who you were. The old mastery has been broken. The flesh still fights, but it no longer reigns. When temptation speaks as if it owns you, answer it with the cross.

10) Take holiness seriously—because God does

Hebrews 12:14 (ESV) — “Strive…for the holiness without which no one will see the Lord.”
And the sweep of 1 Peter 1 makes the same point: you were ransomed by Christ’s blood not merely to be forgiven, but to be renewed—to love earnestly, to live differently, to become a holy people.

If the works of the flesh are the settled, defining pattern of your life—and there is no war, no repentance, no growth, no fruit—then you should not soothe yourself with false confidence. Scripture warns us because God loves us.

But if you are fighting, repenting, returning, praying, seeking help, longing to change—even with weakness and many stumbles—take heart. That is often the very sound of the Spirit’s life within you.

Ask for help: the Father gives the Spirit

In Luke 11, Jesus tells a story about bold, persistent asking—someone knocking at midnight because a need is urgent. And then Jesus draws the conclusion:

Luke 11:13 (ESV) — “…how much more will the heavenly Father give the Holy Spirit to those who ask him!”

Keeping in step with the Spirit is not a self-improvement program. It is not gritting your teeth and trying harder to become impressive. It is the life of a child who keeps coming to the Father, asking for what only the Father can give.

So ask. Ask honestly. Ask repeatedly. Ask like someone who has nothing to prove and everything to receive.

Christ has saved you completely—so now He means to remake you steadily.
You fight because you belong to Him.
You walk because you live by His Spirit.
You pursue holiness because you have already been pardoned.
And you ask for help because your Father delights to give it.

A closing prayer

Father in heaven,
We bless You for grace and peace—purchased by the blood of Christ and applied by the Holy Spirit. Forgive us for treating the Christian life as either self-salvation or spiritual passivity. Teach us to fight from victory, to walk in step with Your Spirit, and to bear fruit that feeds those around us. Renew our minds, capture our thoughts, soften our hearts, and make us like Jesus. And as You have promised, give the Holy Spirit to us as we ask—so that Christ would be formed in us, and Your name would be glorified.

In Jesus’ name, amen.
