A view of the eons or of the ages
When the sovereignties and authorities and powers of the universe were created, they were of spirit only, having no comprehension of righteousness or salvation and, least of all, faith to know God. Their souls were eternal and could not die a final death. God knew He must provide a way for them to enter a dying state and then become a new creation, one that would come to know God by their own faith. He made the eons in Christ Jesus, a world of tangible and visible substance, which could be seen and heard and touched. He brought the souls of those beings into the eons to place them in human bodies. God made Adam and placed him in the garden of Eden. He told Adam not to eat from the tree of the knowledge of good and evil, for the day he disobeyed Him, he would begin to die. When Adam ate of that tree, he did begin to die. Every human being after Adam inherited the same dying state. These are souls of celestial beings having become the souls of humanity. Paul termed this process, both the powerful operation of God and the untraceable riches of Christ (see Eph. 3:7B-12). This was the multifarious wisdom of God acting in accord with the purpose of the eons and made in Christ Jesus our Lord.
Now when Jesus has placed all his enemies under his feet and hands the entire kingdom over to his God and Father, those celestial beings shall be nullified. They will have become swallowed up by humanity and become an all new creation, and God shall be All in all. See 1 Corinthians 15:24-28. ECT
