Book excerpt: Agabus is a mysterious prophetic figure that appears only twice in the book of Acts. Though his role is minor, he is a significant figure in a great debate between cessationists and continualists. On one side are those who believe that the gift of prophecy is on par with the inspired Scriptures, infallible, and has ceased. On the other side are those who define it as fallible and non-revelatory speech that continues today in the life of the church. Proponents of both camps attempt to claim Agabus as an illustration of their convictions. This study defends the position that Agabus' prophecies are true in every detail. Beginning with a survey of major figures in the debate, the author conducts an exegetical analysis of passages where Agabus appears in defense of the infallible view.
