I didn't say anything about lifting judgment; you did. We will all be judged. We will all enter the unquenchable fire of God's love. Some will experience that as an age of life and others an age of punishment, but once all things have been subjected to Christ, God will be all in all. God is the savior of all humanity, especially of those who believe. God has given authority over all flesh to Christ to give eternal life to all he has been given. So, we will all be salted with fire to the end that every knee will bow and every tongue confess that Jesus is Lord.
According to your position, all will never become subject to Christ, and God will never be all in all because God will ensure that evil and sin never end but are perpetuated eternally. Although God created all that is, ex nihilo, and created all that is as good, God will make certain evil is never defeated but persists forever along with the good. It's a twisted form of Manicheism, thanks to Augustine who tried so hard to get away from it. Although there was a time when evil and sin did not exist, God will make sure that once evil and sin enter creation through the will of finite creatures, evil and sin will last as long as God does. Can such a God be good and all-powerful? It's hard to see how.
The UR states that the "everlasting" translates to an "age" that comes to an end. The translation plainly states that "everlasting" referring to an "age" can be translated as an age coming to an end, or an age into infinity, depending on the context. We can go to the Greek to confirm this if necessary.
What does "that God may be all in all" mean"
1 Cor. 15:28
"And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all."
The UR conveniently will not mention the context of 1 Cor 15., that's because Paul is speaking of the resurrection. Paul is arguing the statement made by some, that there is no resurrection of man.
The Scripture makes it clear that Christ is "sitting at the right hand of God until I (God) make your enemies thy footstool. Matt/ 22:44.
This is why Paul tells the Corinthians that God cannot become the "all in all" until the resurrection. Then "all things will be subdued unto Him" (Christ) that God may be "all in all." In other words, Christ is sitting at the right hand of the Father right now, waiting for the Father to make His (Christ) enemies His (Christs') footstool.
This takes place at the resurrection, when all things are brought to Christs' power, which makes the Father "the all in all" of all things.
