The command to love is central to the Gospel of John. Internationally respected scholar Francis Moloney offers a thorough exploration of this theme, focusing not only on Jesus's words but also on his actions. Instead of merely telling people that they must love one another, Jesus acts to make God's love known and calls all who follow him to do the same. This capstone work on John's Gospel uses a narrative approach to delve deeply into a theme at the heart of the Fourth Gospel and the life of the Christian church. Uniting rigorous exegesis with theological and pastoral insight, it makes a substantive contribution to contemporary Johannine scholarship.
