Festus had called Paul's words madness. Paul turned to the king, who "knoweth of these things" (Acts 26:26) and knew the Jewish Scriptures. If Agrippa believed the prophets, he had to take seriously Paul's claim that they foretold "that Christ should suffer, and that he should be the first that should rise from the dead" (Acts 26:22-23). Gill explains the question as asking whether Agrippa believed what the prophets said about Christ's "person, office, sufferings, death, and resurrection" and that it is "fulfilled in Jesus of Nazareth." Paul answers for him at once: "I know that thou believest." Matthew Henry gives the reason: "every one knew that Agrippa professed the Jews' religion."

Agrippa did not answer yes or no. He said, "Almost thou persuadest me to be a Christian" (Acts 26:28). Paul replied, "I would to God, that not only thou, but also all that hear me this day, were both almost, and altogether such as I am, except these bonds" (Acts 26:29). The king rose and the hearing ended. In private the officials agreed, "This man doeth nothing worthy of death or of bonds" (Acts 26:30-31).

Commentators read Agrippa's reply in two ways. Barnes takes it as sincere: "Thou hast nearly convinced me that Christianity is true, and persuaded me to embrace it." Barnes reasons that "Agrippa was a Jew; and, as such, he of course believed the prophets." Matthew Henry notes that "some understand this as spoken ironically," reading it as "Wouldst thou in so little a time persuade me to be a Christian?" He adds that "others take it as spoken seriously," as a confession that Agrippa "was in a manner, or within a little, convinced that Christ was the Messiah," and he dwells longer on that reading. The ESV follows a reading like the ironic one: "In a short time would you persuade me to be a Christian?"

The difference matters. Either Agrippa was close to faith and held back, or he brushed the appeal aside. Both readings leave him short of believing.

Paul's defense began with Israel's hope and ended with a personal appeal. He did not just want to win his case; he wanted the king to believe. Matthew Henry frames the question this way: "Dost thou receive the scriptures of the Old Testament as a divine revelation, and admit them as foretelling good things to come?"

The scene shows that God's word presses for a personal response. Agrippa knew the prophets, and Paul was sure he believed them. But believing the prophets and believing in the One they foretold are not always the same. Paul's reply shows his heart even in chains: he wished that everyone listening might become "altogether such as I am, except these bonds" (Acts 26:29).
