After years of close contact with the Johannine epistles, David Rensberger discusses the numerous puzzles—linguistic, literary, and historical—that characterize these brief texts. His comments on their theological and ethical significance illumines the meaning and interrelationship of faith and love. In short, Rensberger skillfully demonstrates that despite the Johannine epistles' existence on the periphery of the New Testament canon, they nevertheless touch on the heart of its message. Inquiry includes relationship of these epistles to the gospel of John, Christology, Dualism, Eschatology, the Church, and Salvation.
