General Summary of Main Points • Christ's unique person as the God-Man grounds a priesthood and glory no creature can attain; He ministers in the true, heavenly tabernacle and reigns as priest-king at the Father's right hand. • Earthly priests and sacrifices are copies and shadows; Jesus offers Himself and, through His ascension, conducts the necessary eternal intercession in heaven. • The ascension is indispensable: our problem is fundamentally spiritual; only a heavenly, eternal intercessor secures believers perpetually so that none are lost. • The old covenant's inadequacy lies in human failure; Christ fulfills every type and shadow, thereby obtaining a more excellent ministry as Mediator of the better, new covenant enacted on better promises. • Jesus, unlike Israel, resists temptation, refuses wilderness grumbling, obeys perfectly, defeats Satan, and conquers death—functioning as true Israel and the last Adam. • The new covenant brings a people who truly know the Lord; its membership is constituted by genuine faith rather than merely physical descent or external inclusion. • The church era, empowered by the Spirit, advances the gospel globally; Christ's ascension aligns with God's plan for worldwide mission and ongoing heavenly mediation.
