How does Christ's work prepare a way for believers?

The completed work of Christ is foundational for the believer's assurance of salvation and final glorification. As detailed in Ephesians 4:8-10, through His ascension, Christ demonstrated His authority to lead His people, who were once captive to sin, into freedom. He provides the gifts necessary for spiritual growth and service in His kingdom, thereby equipping His church. Moreover, His mission ensures that all who are elect, those chosen by the Father, will ultimately be raised with Him at the last day, as affirmed in John 6:40. Believers can rest in the confidence that their place with Christ is secured not by their deeds but by His grace and intercession as He sits at the right hand of the Father.
