Sometimes when I am loving the Lord Jesus in prayer I call Him "Eternity". Sometimes in adoration of the Father I simply address Him lovingly as
"Eternity".
There is another group who God has judged to be evil and these are destroyed. If you want to believe that 'destruction of the flesh' is the same a 'destroyed' then that's your problem.
There is no "problem" with believing what Paul wrote.
The brothers fallen Adamic way of living is destroyed. His spirit is saved on the day of the Lord.
What God prefers is the we believe that we have been crucified with Christ so that the old fleshy way of living is crossed out, buried with Christ and we are raised to walk in newness of life.
That is faith and voluntary. God is faithful to show that we can put to death the practices of the body through the Holy Spirit.
But if not in faith and voluntarily before the kingdom age what we did not commit to the cross He will destroy at the judgment seat of Christ. That is to suffer loss but to be saved.
There is NO category of Christians who receive Jesus Christ and perish forever being destroyed
spirit, soul, and body. There is NO kind of Christian Once saved is afterwards UNSAVED as to eternal life.
There is no Christian once BORN of God who is afterwards punished forever by being REVERSED in that birth or unborn of God.
