What does the Bible say about Paul's transformation?

In Acts 9, we see Saul, who fervently persecuted Christians, experience a radical transformation after encountering the risen Christ on the road to Damascus. This moment marks the beginning of his new life as Paul, a servant of the gospel. The text emphasizes that this change was entirely a work of God, demonstrating the sovereignty of God's grace in bringing about true repentance and faith. Paul went from seeking to destroy the church to proclaiming Jesus as the Messiah, fulfilling Old Testament prophecies that point to Christ.
