Becoming Holy Means Living at Ease with God

Introduction

Eight days ago, at Numazu church, we held a summer program for children that we call "Joy Joy Special." We gathered in the morning, sang, listened to the word, and shared curry together at lunch. Nothing out of the ordinary, except for one moment: a little boy, proud of his discovery, came up behind me and started tapping the top of my head, asking out loud, "Why is there no hair here?" The girls came running and started tapping too, laughing. I could have boiled over with anger. Ten years ago, I probably would have turned around, hurt, telling myself that was the end of welcoming children into the church.

Yet deep inside, there was a strange peace. Not resignation, not a "whatever," but a calm I could not have manufactured on my own. And that is when I understood something. That peace is the sign that the Holy Spirit is still sanctifying me. I am about to turn sixty, and I had wondered whether age would force me to keep more distance from the children. The answer came through that little fist on my bald head: as long as the Lord allows me to be a pastor, I can keep welcoming them just as before.

This morning, starting from 1 Thessalonians 4:1-12, I want to tell you this: becoming holy does not mean living tense under God's stern gaze. It means living warmly, at ease, with a God who turns everything, even the most embarrassing moments, into something good for you (Romans 8:28).

1. Why Does the Holy Spirit Want to Sanctify You?

Paul writes to the Thessalonians: "This is the will of God, your sanctification" (1 Thes 4:3). He does not say this to frighten you. He says it because he knows the world you live in. A world saturated with temptation, where even someone who has received Jesus remains exposed to the pressure of sin.

You may remember it. The day you believed, the day of your baptism, there was immense joy. That joy has not disappeared; it still carries your life forward. But very soon, in the months that followed, you felt something resurface: harsh thoughts toward your neighbor, words that slipped out, temptations that keep coming back. And you wondered, "How is this possible? I'm a Christian, and yet I still fall. Maybe I'm not a good person after all." That small voice whispering "you're finished," that is Satan's favorite strategy.

Hear me clearly: whether you have believed for six months or forty years, whether you are a pastor or a quiet disciple, you will meet temptation. You will fight inner battles. If you tell me you have never known that struggle, it might be worth going back to check on your salvation, because no longer perceiving sin is not a sign of holiness, it is the opposite: it means the Holy Spirit's light has gone dark somewhere.

So what God wants is to give you what you need to stand firm. To say a clear "no" to temptation. And when you have fallen, when it feels like it is over, not to stay on the ground. That is why you need to welcome the Holy Spirit into your heart every single day. Sanctification is not an optional extra in the Christian life. It is what God uses to keep you standing in a world that keeps pulling you down.

2. How to Receive This Sanctification: The Example of Mary

To understand what a heart open to the Holy Spirit looks like, go read Luke 2:19 and Luke 2:51. Twice, Luke pauses on Mary and notes the same thing: "She kept all these things in her heart, pondering them."

Mary is not naive. She does not believe with her eyes shut, without thinking. She receives the word with her spirit and with her mind. When something happens that she does not understand (shepherds talking about an angel, her son staying behind at the Temple without telling them), she does not reject it, nor does she panic. She holds on to it, turns it over in her heart, and seeks what God wants to tell her through it. That attitude is the soil in which sanctification can grow.

Compare that with Zechariah, in Luke 1:5-20. He was a righteous man, a priest, blameless in keeping the commandments. On paper, he had everything: the title, the seniority, the years of service. When the angel Gabriel announces the birth of John the Baptist, Zechariah answers, "How shall I know this? I am an old man, and my wife is advanced in years." An honestly human reaction; I probably would have said the same. But the angel replies, "You did not believe my words."

When Gabriel visits Mary a few months later, she too asks a question: "How will this be?" Her question sounds like Zechariah's, and yet it rings differently. She does not say "this is impossible." She asks how. And once the angel answers, she concludes, "I am the servant of the Lord; let it be to me according to your word" (Luke 1:38).

It is hard to say, but I will say it anyway: before God, your theology degree carries no weight. Your years of service carry no weight. What carries weight is a living faith today, an open heart that tells God, "I trust you, do as you wish." That is the attitude the Holy Spirit looks for before he comes to live in you. It has nothing to do with your performance. It has everything to do with your availability.

3. How to Recognize That the Spirit Lives in You

Paul continues in 1 Thessalonians 4:9-12. He gives concrete, everyday markers, so that you are not left forever wondering, "Am I really filled with the Holy Spirit?"

First, brotherly love. Not a theoretical love, but a love that shows in how you welcome your brother and your sister, even the one tapping the top of your bald head. Next, a quiet life: not running everywhere, not stirring things up, not meddling in what is not your business. Then, doing your work with diligence, whatever God has entrusted to you as a job, as a family responsibility, as service in the church. Finally, having a good reputation with those outside the church, so that they can see your life holds together.

Notice? None of these signs is spectacular. No extraordinary gifts required. Just a life that breathes peace, diligence at work, faithfulness to the brothers and sisters. That is what the Holy Spirit produces when he comes to live in you. It is not fireworks; it is a steady light.

Look at your own journey. The Lord has used everything, even difficult seasons, even COVID, even the changes of plans forced on your church, to elevate worship, mission, and your own inner boundaries. He was not stopped. He did not let you fall in the middle of the chaos. He gave grace upon grace. And he keeps on giving it.

FAQ

Does becoming holy mean I will stop sinning?
No. Becoming holy means learning to receive God's grace and the Holy Spirit's help every day, so you can stand firm when temptation comes. Christian holiness is not a flawless performance; it is a living relationship with Christ that holds you up.

How do I know if the Holy Spirit lives in me?
1 Thessalonians 4:9-12 gives very simple signs: brotherly love, a quiet life, work well done, a good reputation with those outside the church. If these marks are growing, even slowly, the Spirit is at work.

Why is Mary a better model than Zechariah on this point?
Mary and Zechariah both asked the angel a question. But Mary asked "how" (she wanted to understand in order to obey). Zechariah asked "how shall I know this," demanding proof before believing. Sanctification begins with an open heart that trusts God before it has all the answers.
