Even with the technologies we have today, it is practically impossible to bring a train to a complete stop. Even less possible to turn it completely around. A typical freight train traveling at 55 mph requires over a mile (roughly 18 football fields) to stop in an emergency. The immense weight and low friction of steel wheels on steel rails create mass momentum that makes rapid stops physically impossible.
Paul was like a freight train. He was running at full speed on a campaign to exterminate the movement of Christ. He was practically impossible to stop. Even more, there was no chance anyone could turn him around from his mission. He was convinced his mission was divine, that he was doing the work of God. But God, who is unlike any man, stopped him immediately, turned his heart completely around, and set him on new tracks to go full steam in a different direction.
But when he who had set me apart before I was born, and who called me by his grace, was pleased to reveal his Son to me, in order that I might preach him among the Gentiles, I did not immediately consult with anyone; nor did I go up to Jerusalem to those who were apostles before me, but I went away into Arabia, and returned again to Damascus.
Galatians 1:15-17
Previously, we saw how God conquered Paul. His former life, his violent opposition, and his zealous devotion made it clear that no one was going to persuade him into faith. His conversion required divine intervention. This is where we meet him now, describing the supernatural intervention where Jesus brings him to a full stop and turns him around. He points to God’s plan, God’s call, and God’s purpose.
God’s Sovereign Plan
The Old Testament develops the timelessness of God’s calling of His servants. For instance, God said of Jeremiah, “Before I formed you in the womb, I knew you, and before you were born I consecrated you” (Jer. 1:5). Samson, who might appear as a reactionary solution to the state of Israel, was called “from the womb” to save Israel from the hand of the Philistines (Judg. 13:5). Jesus, which should be no surprise, says from His pre-incarnation, “The Lord called me from the womb” (Is. 49:1). Since God is eternal, His plans are eternal. Everything that happens is sovereignty and providentially unfolding according to His plan.
This is true of the apostle Paul. In fact, he borrows the language of the Old Testament to communicate this, “But when he who had set me apart before I was born” (Gal. 1:15). Being set apart means to be marked off, separated, and designated for a specific purpose. It is what the Lord meant when He spoke of Jeremiah being “consecrated” (Jer. 1:5). Paul recognized the eternal wisdom, foresight, and power of God in his life. Every moment of Paul’s life was leading up to this moment and consequently leading to the next, according to God’s design.
He borrows this language to further drive the point in his main argument—namely, that his gospel was the gospel of God because God interrupted his life and gave him a complete turn around. He was supernaturally picked up from his current projection and set on a completely different track. His conversion could not be explained by human influence. He was too determined to persecute Christ, not submit to Christ’s mission, and yet, that is exactly what happens.
The gospel Paul preached was not shaped by man. It was revealed, confirmed, and formed by Christ Himself.
This also reframes how we understand Paul’s former life. His years in Judaism, his zeal, even his opposition to the church, did not fall outside of God’s knowledge or control. They were part of a larger story that God was writing. That does not excuse Paul’s sin, but it shows that God’s purpose was never at risk. When the time came, God acted in line with what He had already determined.
This is where the weight of the passage lands. Paul’s salvation was not an adjustment. It was the execution of a divine plan. God did not react to Paul. God had already purposed Paul. And when that purpose came into view, it changed everything.
God’s Gracious Call
Paul continues, “and who called me by his grace” (Gal. 1:15). If God’s sovereign design reaches back before Paul’s birth, His gracious call breaks into Paul’s life at a specific moment. The word “called” (καλέσας, kalesas) communicates a decisive summons, one that brings about the very response it requires. When God calls in this way, the call is effective. It does not wait on human willingness. It creates it.
What makes this call stand out is the phrase “by his grace.” Grace is the undeserved favor given freely by God. Paul did not move toward God. His life was moving away from Him. He was opposing Christ and persecuting His people. There was nothing in Paul that prompted this call. It came from God’s initiative alone. That is what makes it grace.
This fits the pattern we see elsewhere in Scripture. When God calls, He does so apart from human merit. He called Abraham out of idolatry. He called Moses out of obscurity. He called David from the fields. In each case, the call begins with God, not man. Paul places himself in that same line. His calling did not arise from his religious effort or his advancement in Judaism. It came from God’s gracious decision to act.
This is where Paul’s story presses into our own. His call was not earned, and it was not sought. It was given. God stepped into his life and turned him around. The same is true of every believer. The call of God is not drawn out by our effort. It is extended by His grace. When that call comes, it brings life where there was resistance and faith where there was opposition. Paul did not enlist. He was called, and that call changed everything.
God’s Personal Revelation
The sovereign design and personal call happened in God’s timing as well as God’s way. Paul adds that the Lord “was pleased to reveal his Son to me” (Gal. 1:16). This is the turning point. The verb “to reveal” (ἀποκαλύψαι, apokalypsai) means to uncover or make known what was hidden. It removes any ideas that argue for Paul’s personal research and intuit. Paul didn’t come to a saving knowledge of Christ until Christ was uncovered before him. In other words, the Lord opened Paul’s heart to understand the truth for the first time. Christ was made clear to him.
Again, the One who is taking action is not Paul, it is God. Paul’s use of “was pleased” points to the reality that this was God’s initiative. God opened the heart. God uncovered the Messiah. God interrupted Paul’s life. Not to beat a dead horse here but it is worth repeating, Paul was not searching for truth. He was opposing it. God opened the eyes of his heart, so that he could see the truth. God acted. Paul responded.
Paul did not reinvent himself. God stepped into his life and changed his entire trajectory.
This also fits Paul’s argument. He has already said that he did not receive the gospel from man or learn it through instruction. Here, he shows how he came to know it. Christ made Himself known. The message Paul preached came from the One who revealed Himself to him. That is why Paul speaks with certainty. His gospel rests on what God has made known, not on what man has reasoned out.
This is how the gospel works. It is not discovered through effort or assembled through study. It is revealed by God. When God opens the eyes, Christ is seen for who He is. That is what happened to Paul. God revealed His Son, and Paul could no longer remain the same.
God’s Gospel Commission
The call to believe in Jesus as Christ was only part of it. The Lord also called Paul into the mission of Christ. He says, “in order that I might preach him among the Gentiles” (Gal. 1:16). This is the purpose behind the call and revelation. God was not content with saving Paul only. He also wanted Paul to be sent into the world with the gospel. From the beginning, God’s work in Paul’s life had direction. His salvation and his mission were tied together.
Paul says that he was commissioned to “preach him,” that is the God of the gospel, to the people outside of the Jewish culture, “among the Gentiles” (Gal. 1:16). The scope of this commission is just as important as the call itself. This would have stood out to his readers. As a man formed within Judaism, Paul would have naturally expected to remain within the Jewish world. Yet God directed him beyond it. His mission crossed the boundaries that once defined his life.
This again supports Paul’s argument. His calling and commission did not come from the apostles in Jerusalem. They did not assign him this role. God did. The same God who set him apart, called him by grace, and revealed His Son also gave him his mission. Paul did not choose this path. It was given to him.
This helps us see the nature of the gospel more clearly. The gospel is not something we hold quietly. It is something we proclaim. When God calls and reveals, He also sends. Paul’s life was redirected for a purpose. He was saved to speak. And that purpose was part of God’s design from the start.
God’s Independent Formation
Paul closes this section by explaining what he did after God called him. “I did not immediately consult with anyone; nor did I go up to Jerusalem to those who were apostles before me” (Gal. 1:16–17). Even after God set him apart, called him by grace, revealed His Son to him, and commissioned him to preach, Paul still did not turn to human influence. He did not seek validation from the apostles or instruction from religious leaders. His gospel did not come from men, and his understanding of it was not shaped by men.
Instead, Paul says, “I went away into Arabia, and returned again to Damascus” (Gal. 1:17). Rather than going to Jerusalem, the center of apostolic leadership, Paul withdrew into Arabia. This was a place removed from the normal channels of influence and instruction. Most commentators suggest that Paul was alone with Jesus for three years, just like the apostles before him (Gal. 1:18). Again, he is hammering the same nail. Christ Himself formed Paul for ministry and gave him the gospel he now preaches. It was revealed by Jesus, confirmed by Jesus, and shaped under the tutelage of Jesus alone. His gospel is not man’s gospel.
Paul’s story brings us back to the freight train. He was barreling down the tracks at full speed, convinced that he was serving God while standing in opposition to Christ. No man could stop him. No argument could turn him around. His momentum was too strong, his convictions too deep, and his zeal too fierce. Then God intervened. The Lord stopped him in his tracks, opened his eyes, redirected his life, and placed him on an entirely different course. That is what grace does. It interrupts rebellion, reveals Christ, and redirects sinners toward God’s purpose. Paul did not reinvent himself or discover a better path. God stepped into his life and changed everything. And because God was the One who called him, revealed Christ to him, commissioned him, and formed him, Paul could say with confidence that the gospel he preached was not man’s gospel. It was God’s gospel from beginning to end.
