“The end of something is better than its beginning…” (Ecclesiastes 7:8)
That’s why it’s true even in principle that Hell cannot be ‘eternal’ since the end of ‘anything He created’ (“thing”) must be ‘better’ no matter how bad the ‘in between is’.
Hence, it’s commonly remarked by some of the earliest fathers of the Greek based churches that this ‘restoration of all things’ may be completed by Him in different stages at the ‘ends of the ages’ framed by the Saying of God.
Far from majority held popular misconceptions among men in this area, “God cannot Fail; He willed The Salvation, Restoration & Reconciliation of the World back to Him, it’ll come to pass no matter how many ages to come it might take”.
Through His only Son, Lord Jesus Christ.
