For sure its all summed up as CHRIST...The Alpha and Omega...The Beginning and the End
Yes, Taffy, the all is ultimately summed up in Christ Jesus the Lord. The language of the Koine is precise: the ta pavnte is brought to summation in the Lord of Glory. Ta pavnte is the all, the all within the heavens, the all within the earth, and the all within the underworld.
And, the language of the Spirit of the Lord, and what He is saying in the present continuous tense is equally precise. That in the dispensation of the fulness of times, He might gather together into Christ the all. This He has cherished in His own mind with consultation from none other, of restoring the whole creation to find its one head in Christ"That God may be all in all" = ina hi o teov panta en pasin.
The final goal of all God's redemptive plans as Paul has so well said in Romans 11:36. -Robertson Word Pictures Of N.T.-
God purposes in His sovereign will that all human history shall be consummated in Christ. Everything that exists in heaven and earth shall find its perfection and fulfillment in Him. AII things shall "center in and tend to consummate and to end in Him.
