Incorrect. Here is another translation of Ephesians 1:7-10 from Young's Literal Translation. Jesus came to unite ALL of creation to himself and Jesus WILL succeed and then give the completed kingdom to God the Father as described in 1 Corinthians 15. Besides, do you really believe that God created beings who he knew would fail and who then punish them FOREVER in Hell?
Ephesians 1:7–10 YLT
7 in whom we have the redemption through his blood, the remission of the trespasses, according to the riches of His grace, 8 in which He did abound toward us in all wisdom and prudence, 9 having made known to us the secret of His will, according to His good pleasure, that He purposed in Himself, 10 in regard to the dispensation of the fulness of the times, to bring into one the whole in the Christ, both the things in the heavens, and the things upon the earth—in him;
The YLT does not say
all creation for a good reason. Stop exaggerating and imagining it says 'all creation' as in all peoples as your objective. And it does not say 'to himself,' either for good reason. Those who possess his spirit and his Father's only, as human beings shall be perfectly restored.
All things or the whole of those things that needs to be restored, to harmonized to a state of living for all those in Christ is a
major part.
There is
no hint here of a universal restoration as I believe you desire this scripture to read. Such a notion would be in fiat contradiction to the doctrine of Divine election, which dominates the whole passage. God’s purpose is to form a united kingdom, consisting of the unfallen and the restored—the unfallen in heaven, and the restored - a completely new formed earth, and to gather this whole body of Christ together under Christ as its Head.
All things in Christ refers to those who are redeemed through faith in Christ, including both believers on earth and good angels who remained faithful. These are the ones who are spiritually "in Christ" and will be brought into perfect unity with Him.
The verse also implies a restoration of harmony between heaven and a new earth, including the renewal of creation itself—the new earth, and most probably animals, and all of nature—delivered from corruption (Romans 8:21) and restored to its original purpose under Christ’s rule.
Again, this gathering is
not universal salvation; it does not include fallen angels or those who reject Christ. The "things in heaven" and "things on earth" are those already united to Christ by grace, not all beings universally.
The Greek word anakephalaioō (to gather together again) emphasizes reunion and restoration—a return to the original state of unity under Christ, broken by the fall of both angels and humans.
If you are not in Christ, you also will not be perfectly restored in Christ, in the Kingdom.
