The concept of all in all is a monumental truth within God's purpose, moving everything toward a time when all things are under God. This ultimate event, as described in I Corinthians 15:28, signifies the moment when Christ completes His work in this creation, submitting all things to the Father, who then becomes all in all. This is the final act Christ performs, ensuring no opposition remains in all of creation to God's rule. It is a vital aspect of our calling, impacting every day of our lives, and something we must anticipate and work toward with spiritual diligence. All in all represents the conclusion of God's plan where everyone and everything will be in total agreement and harmony with each other, reconciled to God. It marks the point when Christ turns everything over to the Father, having defeated all enemies, fulfilling His role in this phase of creation. This event, also referenced in Ephesians 1:23, is the endpoint of the new creation that began in Genesis 1, where Christ, guided by the Father, brings about the complete restitution of all things. Direct aspects of all in all have been part of Christ's assignments from the Father since the beginning, and though a long journey remains, it is the direction toward which we are drawn. We are being prepared for this time, not just for the return of Christ, but for the significant events that follow, ensuring we are ready to participate in God's ongoing work. Without Christ, we cannot produce godly works, as our dependence on Him is absolute, akin to a branch needing to remain attached to the vine to bear fruit. Thus, all in all is not merely an end, but a transition to further responsibilities within God's eternal plan.

In this concluding message of the Jesus in the Feasts series, we reflect on the profound spiritual meaning in the Eighth Day, the final festival in God's annual cycle, revealing Christ as "our all in all." Drawing on the late Charles Whitaker's teaching on merism, a figure of speech in which opposites express totality, this sermon illustrates how the Eighth Day encapsulates the fullness and completeness of God's divine plan through Christ. Scripture gives few details about this day (Leviticus 23:33-36), but its Hebrew term Atzeret denotes closure, restraint, or retention, marking it as the capstone that concludes the Feast of Tabernacles and the entire festival season. Spiritually, it focuses upon Christ, who embodies and fulfills every lesson, hope, and promise depicted in the holy days-our Passover, Bread of Life, King Atonement, and Tabernacle—now summed up in Him who "fills all in all" (Ephesians 1:23). Through passages, including Ephesians 1 and Revelation 2, this message teaches that God's chosen saints as Christ's Body, share in His divine fulness. He is everything we need in every way, our power, holiness, and hope. In Revelation, Jesus declares Himself to be the Alpha and Omega, the beginning and the end, reassuring His people not to fear, but endure faithfully for He reigns and will return soon. Ultimately, the Eighth Day celebrates the completion of God's redemptive work, a vision of eternal unity with Christ, Who fills and perfects all things.
