In Heaven you spend all your time adoring God and meditating upon Him and His infinite goodness. The choirs of angels have the higher choirs like the Seraphim and Cherubim, who more greatly understand and love God, and the lower choirs, who receive from the higher communication about God’s perfections.
So too the saints some are higher some are lower, and those higher in God’s grace and perfection communicate to the lower deeper knowledge of the love of God.
Depending upon one’s merits from life on earth one receives particular rewards and graces in Heaven which others do not receive. The virgins are allowed to sing the canticle in procession after Christ. (Rev. 14:3)
‘Virgins enjoy many privileges. They will have gold crowns, they alone will sing the canticle, they will wear the same garments that Christ wears, they will always march after the Lamb himself.’
St. Jerome, Doctor and Father of the Church
Martyrs, doctors, confessors, each have different rewards…
One admires the beauties of God in the virtues of the angels and saints, one sees God in all the acts of supernatural goodness they performed on Earth and the true and precious value of each of these actions – One see this goodness in one’s brothers and sisters, and their merits and rewards of incalculable beauty. Based upon one’s nature and one’s merit one serves in one capacity or another, one position or another in Heaven… teaching… being taught… interceding…
The angels we are told vie to serve Our Lady. . . whose splendor is greater than all else of Heaven together…
The Seraphim for example are closest to God and most directly contemplate Him, they represent the fire of charity, the Cherubim, represent fullness of knowledge…
When one third of the innumerable angels fell and were condemned to Hell forever, they left empty positions and roles in Heaven. The greatest saints fill these lost roles and positions, until the stars in the Heavens no longer have any gaps.
The extent of one’s beatific vision, greater or lesser, is determined by one’s nature and merits here on earth, should one achieve Heaven. While one is full of joy beyond comprehension in this life, life on earth determines whether one is a relative thimbleful or a great vessel full in the next.
Which is why every little deed matters in this life immeasurably because its consequence are eternally greater or lesser love of God, should one achieve Heaven. Each act of virtue shows our greater capacity for love, for God.
If you have not taken joy in meditating on God on this earth, one might wonder whether one will be spending time in the next life doing something one didn’t pursue or enjoy in this life. … and move quickly to appreciating goodness and virtue more greatly and thinking on the goodness of God, which after all, isn’t anything but good to contemplate.
When all the places in Heaven are filled for predestined men and the places that were the angels, then the world comes to an end.
