The session of Christ refers to His exaltation to the highest place of authority and favor at the Father's right hand following His ascension. From this position, Christ reigns as the Head of His church, interceding for His people, subduing their enemies, and governing all things for their eternal good.
The session of Christ signifies that our Savior, having finished His work of redemption, has been advanced to the seat of supreme authority. As the Westminster Larger Catechism Q.54 explains, Christ, as the God-man, is exalted to the highest favor with the Father, holding all power in heaven and on earth. He is not merely resting, but actively ruling, gathering and defending His church while subduing those who stand against it. The Heidelberg Catechism Q.50 adds that Christ has ascended for the purpose of appearing as the Head of His church, through whom the Father governs all things. This reality reminds us that despite the chaos of this world, the risen Christ remains upon the throne, ensuring that the gospel advance will never be thwarted.
The session of Christ is not a cold theological abstraction but a source of profound comfort for the believer. Because Christ is our advocate in the presence of the Father, we have an unbreakable assurance of our standing before God, rooted in His finished work rather than our own performance. As the Heidelberg Catechism Q.49 notes, the fact that our human flesh is now in heaven is a sure pledge that Christ, as our Head, will eventually bring us into His glory. We are invited to rest in the finished work of our Savior, who intercedes for us even now: Hebrews 7:25. We are indeed more sinful than we dared believe, yet because of Christ's position at the right hand of the Father, we are more accepted and loved in Him than we ever dared hope.
