“It is the crucified but also the resurrected and exalted Christ whom the apostles proclaim. From that vantage point of the exaltation of Christ, they view and describe His earthly life, suffering, and death.
For the work He now carries out as the exalted mediator, He laid the foundations in His cross. In His battle with sin, the world, and Satan, the cross has been His only weapon.
By the cross He triumphed in the sphere of justice over all powers that are hostile to God. But in the state of exaltation, consequently, He has also been given the divine right, the divine appointment, the royal power and prerogatives to carry out the work of re-creation in full, to conquer all His enemies, to save all those who have been given Him, and to perfect the entire kingdom of God.
On the basis of the one, perfect sacrifice made on the cross, He now—in keeping with the will of the Father—distributes all His benefits. Those benefits are not the physical or magical aftereffect of His earthly life and death.
It is the living and exalted Christ, seated at the right hand of God, who deliberately and with authority distributes all these benefits, gathers His elect, overcomes His enemies, and directs the history of the world toward the day of His parousia.
He is still consistently at work in heaven as the mediator. He not only was but still is our chief prophet, our only high priest, and our eternal king.
He is the same yesterday, today, and forever.”
