Acts 9 Devotional — Unfathomable Calling & Change

This morning I sat down for my Acts 9 devotional and found myself face to face with the conversion of Saul — one of the most famous stories in Scripture. It’s the kind of passage you think you already know, but every time I read it, something different catches me. Today I stopped at verses 13 through 19, where Ananias enters the story. Three things gripped me: God’s unfathomable calling, Ananias’s trembling obedience, and the sheer totality of Saul’s transformation.

“But the Lord said to him, ‘Go, for he is a chosen instrument of mine to carry my name before the Gentiles and kings and the children of Israel.'” — Acts 9:15 (ESV)

Acts 9 falls into two halves. Reading through this Acts 9 devotional, I noticed the structure clearly: the first half (verses 1–31) covers Saul’s conversion and early ministry; the second (verses 32–43) follows Peter’s work in Lydda and Joppa. In the first half, the church’s fiercest persecutor is drawn inside the gospel. In the second, that gospel pushes outward. The thread running through the entire chapter is the unstoppable expansion of the good news. And at the hinge of it all stands the trembling obedience of an otherwise unknown disciple named Ananias.

A Calling Beyond Human Logic

God tells Ananias to go. Go to Saul. Just imagine how absurd that sounded. Saul was the man who had been dragging believers out of their homes in Jerusalem. He was on his way to Damascus with official letters authorizing him to do the same there. And God calls this man “a chosen instrument.”

I kept asking myself: could I have guessed this plan? Honestly, no. God’s calling is not just surprising — it’s often incomprehensible. If you were hiring based on résumés, Saul would be the last candidate. He was the enemy of the church. But God wasn’t reading his résumé. He was looking at the plan He intended to accomplish through him.

This echoes a pattern I’ve been noticing throughout the Gospel of John. Jesus always seeks people out first. He found the blind man (John 9), He went to the Samaritan woman (John 4), and on the road to Damascus, He struck Saul down before Saul ever thought to look for Him. The subject of calling is always God, never us. “You did not choose me, but I chose you” (John 15:16) — for Saul, this was not a theological proposition. It was lived experience.

If you’ve been following this series, you may remember how the early church in Acts 5 was described as unstoppable because it was “of God.” Saul’s conversion is the most dramatic proof of that truth. The very man who tried to overthrow the church became its greatest missionary — because the calling was God’s, not man’s.

The Heart of This Acts 9 Devotional — Ananias’s Obedience, Calling Your Enemy “Brother”

The moment in this Acts 9 devotional that shook me most was Ananias’s response. In verses 13 and 14, he essentially talks back: “Lord, I have heard from many about this man, how much evil he has done to your saints at Jerusalem. And here he has authority from the chief priests to bind all who call on your name” (Acts 9:13–14, ESV). This isn’t a neutral briefing. It’s a plea — “Are you sure? This man?”

I wanted to dig into an analogy that captures the weight of what was being asked. During the Japanese colonial rule of Korea, resistance fighters were hunted, tortured, and imprisoned by colonial officers. Now imagine God saying to one of those fighters: “Go to that officer. Receive him as your comrade.” That is the scale of what Ananias was asked to do. Not merely to meet a stranger, but to embrace the very person who had been hunting his people — and who was coming to hunt him.

And yet, after one protest, he goes. Verse 15: “Go.” And he went. But what strikes me most is the first word out of his mouth when he reaches Saul in verse 17: “Brother Saul” (Ἀδελφέ Σαούλ, Adelphe Saoul). He called his enemy “brother.” This was not just physical obedience — feet moving to a location. This was a wholesale rearrangement of the heart’s categories. The line between enemy and family was redrawn inside the gospel.

Think back to Acts 4, where Peter and John stood before the Sanhedrin and proclaimed the cornerstone the builders rejected. Ananias, in his own quiet way, is doing the same thing here — accepting what human logic would reject, because God said so.

Saul’s Conversion — The Response of a Man Overwhelmed by Grace

The passage itself (13–19) doesn’t detail Saul’s transformation in full. But from verse 19 onward the change is staggering. “And immediately he proclaimed Jesus in the synagogues, saying, ‘He is the Son of God'” (Acts 9:20, ESV). Days earlier, he was the hunter. Now he was the herald.

Reading this, I couldn’t help but think: when God truly calls a person, this is the scale of change that follows. But I have to be careful with that thought. Read through the lens of legalism, it becomes a crushing demand: “You should be changing this much too.” But through the lens of the gospel — through Tim Keller’s framework that has become central to my reading — Saul didn’t change because he was supposed to. He changed because the light on the Damascus road, that voice, that grace, was so overwhelming that his former life simply became impossible.

Obedience was not the condition of acceptance. It was the natural overflow of having been accepted. As Paul himself would later testify, everything he once counted as gain he came to regard as rubbish, because of the surpassing worth of knowing Christ Jesus (Philippians 3:7–8). The change was total because the grace was total.

The Gospel Does Not Stop — Peter’s Ministry and the Bigger Picture of Acts 9

Wrapping up this Acts 9 devotional, I also looked at verses 32–43. At first glance they seem like a separate episode, but I’m told Luke’s placement here is deliberate. Peter travels through Lydda and Joppa, healing Aeneas and raising Tabitha. The very things Jesus did during His earthly ministry — healing the sick, raising the dead — are now being done through human hands. It’s a picture of the gospel expanding beyond Jerusalem, just as Acts 1 promised it would when Jesus said, “You will be my witnesses.”

I wanted to dig into the parallel, and it turns out Peter’s raising of Tabitha (Acts 9:40) closely mirrors Jesus raising Jairus’s daughter (Mark 5:40–41). Peter sends everyone out, kneels to pray, then speaks: “Tabitha, arise” — a reenactment of “Talitha cumi.”

And there’s a small detail at the end that’s easy to miss. Verse 43 tells us Peter stayed at the house of Simon the tanner. Tanners were considered ritually unclean under Jewish law. This is a quiet foreshadowing of Acts 10 — where the gospel crosses the boundary into the Gentile world through Cornelius. The walls are already coming down.

In the Gospels, Jesus teaches directly: “I am the vine; you are the branches.” In Acts, those words are woven into action. There are no sermons to quote, only footsteps to trace. You have to read the theology out of the choices people make, the doors they walk through, the names they call each other. That is what made this Acts 9 devotional both harder and richer than a Gospel passage. For most of us, the voice from heaven is rare. What we have are trembling steps of obedience — and the quiet trust that the One who called us knows what He is doing.

A Prayer to Close This Acts 9 Devotional

Lord, as I read Acts 9 this morning, I am humbled before Your calling.

That You would choose someone like Saul — who could have imagined it? Forgive me for the smallness of my judgment, for measuring people by their past instead of by Your plan. Like Ananias, I may hesitate. I may protest. But give me the grace to take that next step anyway — to walk toward the very people and situations that frighten me, trusting that You have gone before me.

And Lord, let me be overwhelmed by Your grace the way Saul was. Not a forced change, not a dutiful adjustment, but the kind of transformation that comes when knowing You becomes so surpassingly great that the old life simply falls away.

In the name of our Lord Jesus Christ I pray. Amen.
