a holy God? In the book of Hebrews, Jesus Christ is celebrated as the great high priest who represents his people before the Father. Jesus' roles as priest and mediator are central to his identity and bring to completion themes woven throughout Scripture. In this fifth ESBT volume, T. Desmond Alexander considers the often-neglected themes of priesthood and mediation and how Christ fulfills these roles. He explores how these concepts illuminate what Christ has already accomplished for us through his self-sacrifice, as well as what he is presently achieving on our behalf, seated at the right hand of the Majesty in heaven. Through this study we gain a richer understanding of concepts such as holiness, sacrifice, covenant, reconciliation, and God's dwelling place. Essential Studies in Biblical Theology (ESBT), edited by Benjamin L. Gladd, explore the central or essential themes of the Bible's grand storyline. Taking cues from Genesis 1-3, authors trace the presence of these themes throughout the entire sweep of redemptive history. Written for students, church leaders, and laypeople, the ESBT offers an introduction to biblical theology.
