How do we know that Jesus fulfills all things after His ascension?

The assurance that Jesus fulfills all things is rooted in Ephesians 4:10, which states that He ascended to fill all things. Believers can trust that His ascension does not signify abandonment; rather, it marks the beginning of His reign and the active impartation of grace to His body, the Church. Christ’s ascension means that He has been appointed as the head of the Church, ensuring that every member, no matter how poor or lacking, receives nourishment and care from Him. Furthermore, His ascension sends the Holy Spirit, who empowers believers and dispenses gifts according to His sovereign will. This continual relationship allows Christians to experience the fullness of Christ in their lives, as He is actively involved in their spiritual growth and sustenance.
