Peter lived daily with Jesus, but when Jesus was arrested, Peter denied that he knew Jesus three times.
Saul was a persecutor of Christians. He was responsible for many early Christians being put to death. He then experience the power of the risen Jesus and became absolute in his faith that Jesus is the Son of God. After his experience, he changed his name to Paul.
Both Peter and Paul chose death rather than deny Jesus.
Peter was not absolutely sure that Jesus is who He is. He had doubt and he was afraid for his own life. After Jesus was resurrected from the dead and appeared to Peter and many others, Peter chose crucifixion rather than deny Jesus again. Peter knew Jesus is who He is; Peter no longer had any doubt.Matthew 26:69-75
<sup id="en-NIV-24121">69</sup>Now Peter was sitting out in the courtyard, and a servant girl came to him. "You also were with Jesus of Galilee," she said. <sup id="en-NIV-24122">70</sup>But he denied it before them all. "I don't know what you're talking about," he said.
<sup id="en-NIV-24123">71</sup>Then he went out to the gateway, where another girl saw him and said to the people there, "This fellow was with Jesus of Nazareth."
<sup id="en-NIV-24124">72</sup>He denied it again, with an oath: "I don't know the man!"
<sup id="en-NIV-24125">73</sup>After a little while, those standing there went up to Peter and said, "Surely you are one of them, for your accent gives you away."
<sup id="en-NIV-24126">74</sup>Then he began to call down curses on himself and he swore to them, "I don't know the man!"
Immediately a rooster crowed. <sup id="en-NIV-24127">75</sup>Then Peter remembered the word Jesus had spoken: "Before the rooster crows, you will disown me three times." And he went outside and wept bitterly.
Saul was a persecutor of Christians. He was responsible for many early Christians being put to death. He then experience the power of the risen Jesus and became absolute in his faith that Jesus is the Son of God. After his experience, he changed his name to Paul.
Paul chose imprisonment and eventually was beheaded rather than give up his faith in Jesus.Acts 9:1-22
<sup id="en-NASB-27218">1</sup>Now Saul, still breathing threats and murder against the disciples of the Lord, went to the high priest, <sup id="en-NASB-27219">2</sup>and asked for letters from him to the synagogues at Damascus, so that if he found any belonging to the Way, both men and women, he might bring them bound to Jerusalem.
<sup id="en-NASB-27220">3</sup>As he was traveling, it happened that he was approaching Damascus, and suddenly a light from heaven flashed around him;
<sup id="en-NASB-27221">4</sup>and he fell to the ground and heard a voice saying to him, "Saul, Saul, why are you persecuting Me?"
<sup id="en-NASB-27222">5</sup>And he said, "Who are You, Lord?" And He said, "I am Jesus whom you are persecuting,
<sup id="en-NASB-27223">6</sup>but get up and enter the city, and it will be told you what you must do."
<sup id="en-NASB-27224">7</sup>The men who traveled with him stood speechless, hearing the voice but seeing no one.
<sup id="en-NASB-27225">8</sup>Saul got up from the ground, and though his eyes were open, he could see nothing; and leading him by the hand, they brought him into Damascus.
<sup id="en-NASB-27226">9</sup>And he was three days without sight, and neither ate nor drank.
<sup id="en-NASB-27227">10</sup>Now there was a disciple at Damascus named Ananias; and the Lord said to him in a vision, "Ananias." And he said, "Here I am, Lord."
<sup id="en-NASB-27228">11</sup>And the Lord said to him, "Get up and go to the street called Straight, and inquire at the house of Judas for a man from Tarsus named Saul, for he is praying,
<sup id="en-NASB-27229">12</sup>and he has seen in a vision a man named Ananias come in and lay his hands on him, so that he might regain his sight."
<sup id="en-NASB-27230">13</sup>But Ananias answered, "Lord, I have heard from many about this man, how much harm he did to Your saints at Jerusalem;
<sup id="en-NASB-27231">14</sup>and here he has authority from the chief priests to bind all who call on Your name."
<sup id="en-NASB-27232">15</sup>But the Lord said to him, "Go, for he is a chosen instrument of Mine, to bear My name before the Gentiles and kings and the sons of Israel;
<sup id="en-NASB-27233">16</sup>for I will show him how much he must suffer for My name's sake."
<sup id="en-NASB-27234">17</sup>So Ananias departed and entered the house, and after laying his hands on him said, "Brother Saul, the Lord Jesus, who appeared to you on the road by which you were coming, has sent me so that you may regain your sight and be filled with the Holy Spirit."
<sup id="en-NASB-27235">18</sup>And immediately there fell from his eyes something like scales, and he regained his sight, and he got up and was baptized;
<sup id="en-NASB-27236">19</sup>and he took food and was strengthened. Now for several days he was with the disciples who were at Damascus,
<sup id="en-NASB-27237">20</sup>and immediately he began to proclaim Jesus in the synagogues, saying, "He is the Son of God."
<sup id="en-NASB-27238">21</sup>All those hearing him continued to be amazed, and were saying, "Is this not he who in Jerusalem destroyed those who called on this name, and who had come here for the purpose of bringing them bound before the chief priests?"
<sup id="en-NASB-27239">22</sup>But Saul kept increasing in strength and confounding the Jews who lived at Damascus by proving that this Jesus is the Christ.
Both Peter and Paul chose death rather than deny Jesus.
The earliest mention that we have of Peter's death is in a letter from Clement, bishop of Rome (AD 88-97), to the Corinthians. He mentions the suffering and martyrdom of Peter and Paul in Rome.
Dionysius, bishop of Corinth, bears the following testimony (about AD 180) referring to Peter and Paul: "Both of these having planted the church at Corinth, likewise instructed us; and having in like manner taught in Italy, they suffered martyrdom about the same time."
About AD 200, Tertullian, a Christian teacher, mentions the deaths of Peter and Paul as occurring in Rome under Nero.
Peter's death is also found in Caius, an ecclesiastical writer (3rd century), who says that Peter and Paul "suffered martyrdom about the same time."
Eusebius in his book entitled Ecclesiastical History (written AD 325) says: "Thus Nero publicly announcing himself as the chief enemy of God, was led on in his fury to slaughter the apostles. Paul is therefore said to have been beheaded at Rome, and Peter to have been crucified under him. And this account is confirmed by the fact, that the names of Peter and Paul still remain in the cemeteries of that city even to this day" (Ecclesiastical History 2:25).
