Who was the Apostle Paul in the Bible?

from the old testament

• Paul was an Israelite and a descendant of Abraham. Although the Old Testament does not mention Paul, it establishes the covenant identity that Paul later claimed for himself, since God chose Abraham and his descendants to be His covenant people and promised that through Abraham all the nations of the earth would be blessed (Genesis 12:1–3; 17:1–8; 22:15–18; see Romans 11:1). This background is essential for understanding why Paul viewed the gospel as the fulfillment of God's ancient promises rather than as a new religion disconnected from Israel's story.
• Paul belonged to the tribe of Benjamin. Benjamin was one of the twelve tribes descended from Jacob (Genesis 35:16–18; 49:27), and Paul's identification with Benjamin shows that he was thoroughly Jewish by ancestry and covenant identity (see Romans 11:1; Philippians 3:5). Benjamin also produced Israel's first king, Saul, which makes Paul's Hebrew name, Saul, particularly fitting within his Israelite heritage (1 Samuel 9:1–2).
• Paul was shaped by the Law and the Scriptures of Israel (Deuteronomy 6:4–9; Psalm 19:7–11; Isaiah 53). This explains why Paul's letters are saturated with quotations and allusions to the Old Testament and why he repeatedly argued that the gospel was consistent with what God had already revealed.
  
• The Old Testament anticipated a coming King from David's line who would reign forever, and it also described God's Servant who would suffer for the sins of others (2 Samuel 7:12–16; Psalm 2; Isaiah 9:6–7; Isaiah 52:13–53:12). Paul identified Jesus as this promised Messiah, explaining that Christ's death and resurrection occurred "in accordance with the Scriptures" (1 Corinthians 15:3–4).
• From the beginning, God told Abraham that all the families of the earth would be blessed through him (Genesis 12:3; 18:18; 22:18). Paul understood his calling to preach Christ among the Gentiles as part of God's long-standing purpose (Romans 15:8–12; Galatians 3:6–9).
• The Old Testament anticipated the nations coming to worship the Lord. Israel's prophets repeatedly looked forward to a day when God's salvation would extend beyond Israel to the nations (Psalm 22:27–28; Psalm 67:1–7; Isaiah 42:6; 49:6; 56:6–8). Paul therefore saw the conversion of Gentiles through the gospel as the fulfillment of God's revealed plan to bring salvation to the ends of the earth.
• The Old Testament established humanity's universal problem of sin. From the fall of Adam onward, Scripture portrays humanity as rebellious and unable to make itself righteous before God (Genesis 3; Psalm 14:1–3; Psalm 51:5; Isaiah 53:6). Paul's teaching that "all have sinned and fall short of the glory of God" therefore stands within the larger biblical diagnosis of humanity's need for God's saving grace (see Romans 3:23).
  
• The Old Testament provided the foundation for Paul's teaching about righteousness by faith. Abraham's faith was "counted to him as righteousness" (Genesis 15:6), and Habakkuk declared that "the righteous shall live by his faith" (Habakkuk 2:4). Paul appealed to these passages to explain that God's people have always depended upon faith in God's promise rather than boasting in their own works (see Romans 4:1–8; Galatians 3:6–9).
• Jeremiah promised a new covenant in which God would write His law on His people's hearts and remember their sins no more, while Ezekiel promised that God would cleanse His people and give them a new heart and His Spirit (Jeremiah 31:31–34; Ezekiel 36:25–27). Paul's teaching about the new covenant in Christ therefore builds upon these prophetic promises (see 2 Corinthians 3:4–6).
  
• The Old Testament anticipated God's victory over death. Scripture contains an emerging hope that God would ultimately destroy death and raise His people to life (Isaiah 25:7–8; 26:19; Daniel 12:2). Paul proclaimed Christ's resurrection as the decisive fulfillment and foundation of this hope, making resurrection central to the Christian gospel (1 Corinthians 15:12–26).
  
• The Psalms and prophets describe God's anointed King receiving the nations as His inheritance and bringing God's reign to the ends of the earth (Psalm 2:7–12; Psalm 72:8–11; Isaiah 11:10). Paul's proclamation that Jesus is Lord and that His kingdom extends to the nations belongs within this larger biblical expectation.

from the new testament

• Paul was originally known by his Jewish name, Saul. The New Testament first introduces him as Saul, a young man who approved of Stephen's execution and participated in the persecution of the early church (Acts 7:58–8:3). Luke later identifies him as Paul, the name by which he is primarily known throughout his Gentile missionary ministry (Acts 13:9).
• Paul told the Jerusalem crowd that he was "a Jew, born in Tarsus in Cilicia, but brought up in this city" of Jerusalem (Acts 22:3). His background therefore combined a Jewish covenant identity with upbringing in the broader Greco-Roman world, which helps explain his ability to operate across both Jewish and Gentile settings.
  
• Paul told the Roman commander that he possessed Roman citizenship from birth (Acts 22:25–29), and that this citizenship sometimes afforded him legal protections during his missionary ministry (Acts 16:35–39). His Roman citizenship also helps explain how his ministry eventually reached the heart of the Roman Empire.
  
• Paul said that he had been educated "at the feet of Gamaliel" according to the strict manner of the Jewish law and that he was a Pharisee (Acts 22:3; 23:6). He therefore understood the Hebrew Scriptures and Jewish theological traditions exceptionally well, which became important when he later demonstrated how they pointed toward Christ.
  
• Paul described himself as having advanced in Judaism beyond many of his peers and as being exceedingly zealous for the traditions of his fathers (Galatians 1:13–14). His zeal was sincere but tragically misdirected because he believed that persecuting followers of Jesus was an act of faithfulness to God (Acts 26:9–11).
  
• Before his conversion, Paul imprisoned Christians, tried to destroy the church, and approved of the death of Stephen (Acts 7:58–8:1; 8:3; 9:1–2). Paul later acknowledged the seriousness of his former actions, calling himself a "blasphemer, persecutor, and insolent opponent" who had received mercy from Christ (1 Timothy 1:13–16).
  
• While traveling to Damascus to arrest Christians, Paul was confronted by a heavenly light and heard Jesus ask, "Saul, Saul, why are you persecuting me?" (Acts 9:1–5; 22:6–8; 26:12–15). This encounter became the decisive turning point of his life because the persecutor of Jesus' followers discovered that Jesus truly was the risen Lord.
  
• Paul was personally commissioned by Jesus Christ. Jesus told Ananias that Saul was a "chosen instrument" who would carry His name before Gentiles, kings, and the children of Israel (Acts 9:15–16), and Paul later explained that Christ had personally appeared to him and appointed him as a servant and witness (Acts 26:16–18). Paul, therefore, understood his apostleship as a divine calling rather than merely a position granted by other Christians.
  
• Paul was particularly called to preach the gospel to the Gentiles (Romans 11:13; Galatians 2:7–9). Through Paul, the gospel moved from the Jewish world into the nations.
  
• When Paul entered Jewish synagogues, he reasoned from the Scriptures that Jesus was the Christ, and he summarized his gospel as Christ's death for sins, burial, and resurrection (Acts 17:2–3; 1 Corinthians 15:3–4).
  
• Paul taught that salvation is by God's grace through faith in Christ. Paul explained that all people are sinners and that justification comes through faith in Jesus Christ rather than through works of the Law (Romans 3:21–28; Galatians 2:15–16). He emphasized that salvation is God's gracious gift rather than something human beings can earn (Ephesians 2:8–9).
  
• Paul explained that Christ's death had broken down the hostility between Jew and Gentile and created one people reconciled to God through Him (Ephesians 2:11–22). All who belong to Christ are Abraham's offspring according to the promise (Galatians 3:28–29).
• Paul expressed "great sorrow and unceasing anguish" over his fellow Israelites and said that his heart's desire and prayer was for their salvation (Romans 9:1–5; 10:1).
  
• Paul became a missionary who traveled extensively to proclaim Christ and establish churches. Acts 13–20 record Paul's missionary journeys through regions including Galatia, Macedonia, Achaia, and Asia, while his letters show his ongoing work to strengthen the churches he had established. Paul described his ministry as planting while God gave the growth (1 Corinthians 3:5–9), emphasizing that the ultimate power behind his missionary work belonged to God.
• Paul explained that he made it his ambition to preach the gospel where Christ had not already been named (Romans 15:20–21).
  
• Paul was a pastor who cared deeply about the spiritual health of believers. His letters repeatedly reveal his affection, prayers, concern, correction, and desire for the spiritual maturity of the churches (2 Corinthians 11:28; Galatians 4:19; Philippians 1:3–11; Colossians 1:28–29). Paul therefore should not be viewed merely as a traveling theologian; he was deeply invested in the people who had come to faith through his ministry.
• Paul was a major theological teacher of the early church. His letters explain some of the New Testament's most important teachings about sin, justification, sanctification, the Holy Spirit, the church, spiritual gifts, love, resurrection, Christian marriage, suffering, and Christ's return (Romans; 1 Corinthians; Galatians; Ephesians; Philippians; Colossians; 1–2 Thessalonians). His theology consistently centers on what God has accomplished through the death and resurrection of Jesus.
• Paul endured imprisonment, beatings, shipwrecks, danger, hunger, persecution, and continual pressure for the churches (2 Corinthians 11:23–28). Rather than viewing these hardships as defeating his ministry, Paul saw them as opportunities for the life and power of Jesus to be displayed through his weakness (2 Corinthians 4:7–12).
  
• Paul also learned to depend upon Christ's strength in his weakness. When Paul pleaded with God to remove his "thorn in the flesh," Christ answered, "My grace is sufficient for you, for my power is made perfect in weakness" (2 Corinthians 12:7–10). All we do comes from the sufficient grace and power of Christ.
  
• Although he possessed apostolic authority, Paul insisted that he and other Christian leaders were servants through whom people believed and that the message was not about themselves but about Jesus Christ as Lord (1 Corinthians 3:5–9; 2 Corinthians 4:5). His ministry consistently directed attention away from Paul and toward Christ.
  Paul never forgot that he had once persecuted the church. He called himself "the least of the apostles" because he had persecuted God's church and said that he was unworthy to be called an apostle (1 Corinthians 15:9). Yet Paul immediately attributed his transformed life and ministry to God's grace: "By the grace of God I am what I am" (1 Corinthians 15:10).
  
• Paul's life is evidence of the power of the gospel. Paul described himself as the foremost of sinners who had nevertheless received mercy so that Christ's perfect patience might be displayed through him as an example to others (1 Timothy 1:12–16). His life became a living testimony to the fact that God's grace can completely transform anyone!
• Paul wrote thirteen New Testament letters that bear his name. The New Testament attributes Romans through Philemon to Paul, and these letters preserve his teaching to churches and individuals about how the gospel should shape belief and life. Hebrews should not be included among Paul's letters when describing what Scripture itself establishes because Hebrews never identifies its author.
  
• Paul remained faithful to Christ despite the cost of his calling. Paul told the Ephesian elders that he did not consider his life precious compared with finishing the ministry Christ had given him (Acts 20:24), and near the end of his recorded ministry, he declared, "I have fought the good fight, I have finished the race, I have kept the faith" (2 Timothy 4:7–8). The Bible therefore presents Paul as someone who persevered faithfully until the end of his apostolic ministry.

implications for today

Who are you, and what are you known for? Maybe you're known for your career, your personality, your relationships, your accomplishments, your mistakes, or the way you present yourself to others. But what happens when the things that have defined you change? Paul's life shows us that the gospel has the power to completely transform our identity and redirect the purpose of our lives. Saul was known as a persecutor of Christians, but after encountering the risen Jesus, he became Paul, an apostle who devoted his life to proclaiming the very Christ he once opposed. His past no longer had the final word—Christ did.

Paul's transformation wasn't merely an emotional experience or a change in religious beliefs; it changed the direction of his entire life. He gave up status, comfort, security, and personal ambition to follow Jesus and make Him known. His life reminds us that the gospel is worth living for. When we truly understand who Jesus is and what He has done for us, following Him becomes more valuable than protecting our comfort or building a name for ourselves, especially when we know that living for Him impacts our lives both now and for eternity. The gospel gives us a purpose greater than anything else the world tells us will define a meaningful life.

Paul's life also invites us to consider what is defining us right now. Are we allowing our past, our achievements, our fears, or the opinions of others to determine who we are? Or are we allowing Christ to define us and shape the direction of our lives? Transformation doesn't mean becoming someone impressive; it means becoming more like Christ and living for what matters to Him. We live for God's kingdom while in this world, with eternal purpose. Paul went from being known for persecuting Christ to being known for living for Christ—and the same gospel that transformed him calls us to surrender our lives to Jesus and discover that He is worth everything.
