The Apocalypse is written from beginning to end of the history of the world by God Himself. It includes all the ages of the world. It also includes all people that have ever existed or will ever exist. God and His Christ are the only Judge of all people. We aren't. We are to love God with our whole heart and soul and depth of being and our neighbor as ourselves.

A brief explanation of the ages.
There are covenants and ages (biblical days), which by God's providence, all point to and are summed up in the pre-existent covenant of salvation given in Christ Himself on His Most Holy Cross. See here for a summation:
Seven Ages:St. Isidore -- The First and Second ages of the World
St. Isidore -- The Third Age of the World and The Fourth Age of the World
St. Isidore -- The Fifth Age of the World and Sixth Age until St. John
St. Isidore -- The Sixth age of the World until St. Ambrose
St. Isidore -- The Sixth Age of the World until 616 A.D.
The Church Fathers, especially including St. Irenaeus (180 A.D.) and St. Augustine (d. 430 A.D.), and the Old Testament prophets, especially St. Ezekiel, by God's grace, saw the ages of the world in a literal and mystical sense at the exact same time. The following is a summation of what they taught. St. Isadore of Seville (d. 636 A.D.), above, based all of what he wrote about the ages of the world on what the Church Father's before him had taught. St. Isadore is the last of the Church Fathers in the West (Doctors of the Church are a different and mostly later grouping).
