What does Acts 26:20 mean?
In a speech before Agrippa II, Paul is describing how Jesus commissioned him to spread an offer of divine forgiveness. Paul had once violently persecuted the church but met Jesus on his way to Damascus to arrest Jewish Jesus-followers. Instead of attacking the Christians, Paul became one. Furthermore, Jesus claimed him as a messenger to Jews, Gentiles, and kings (Acts 9:15). It is both ironic and a partial fulfillment of prophecy that Agrippa is a king with both Jewish and Gentile blood.Before Jesus ascended into heaven, He charged the disciples to be His witnesses, "in Jerusalem and in all Judea and Samaria, and to the end of the earth" (Acts 1:8). Paul's ministry has followed a similar trajectory, although he started by leaving Damascus and spending three years in Arabia, the desert to the east (Galatians 1:17–18). Only after the Jewish leaders in Damascus threatened to kill him did he return to Jerusalem (Acts 9:23–26). He stayed fifteen days until Jews from outside Judea, again, threatened to kill him, and both Jesus and the apostles sent him home to Tarsus (Acts 9:29–30; 22:17–21).
After several years in Tarsus, Barnabas came to him and asked for help building the church in Syrian Antioch (Acts 11:19–26). Paul spent the next several years in Syria, modern-day Turkey, Macedonia, and Greece teaching Jews and Gentiles about Jesus' offer of salvation. We aren't told when Paul told people about Jesus in Judea.
To "repent" is simply to accept that our way is wrong, and Jesus' is right, and to allow Jesus to fix that error in us. Many people, however, are confused about the relationship between faith in Jesus and good works. Ephesians 2:8–10 echos the message of this verse:
"For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast. For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them."Salvation is by grace alone, through faith alone. There is no way our works can earn salvation or ensure we keep salvation. Throughout the centuries, Christians—including Martin Luther—argued over whether Paul's description of salvation contradicts James' assertion that "faith by itself, if it does not have works, is dead" (James 2:17). James, however, is not saying salvation requires faith and works. He's saying that if someone does not exhibit the works which naturally come from a heart indwelt by the Holy Spirit, that person is not saved. A person totally lacking in good works has not truly repented and they do not have true faith. We do good works because we have faith and have repented—because we are saved. There are no works we can do to earn salvation.
