God said to David’s Lord, “Sit at My right hand till I make Your enemies Your footstool” (Mark 12:36). When we study the biblical narratives of the life and work of Jesus, as well as the apostolic commentaries on those narratives, we discover moments of supreme importance in terms of redemptive history. These include His birth, His death on the cross, His resurrection, the Day of Pentecost, and His return. However, there is an element in the work of Christ that we almost completely overlook. It is the session of Jesus.
