“The final rest of God’s children is not to be conceived as inaction; His children remain His servants, who joyfully and in diverse ways serve Him night and day.
What we sow on earth is harvested in eternity; diversity is not destroyed in eternity but cleansed from sin and made serviceable to fellowship with God and others. Scripture even teaches degrees of glory in the future kingdom, commensurate with one’s works.
The blessedness of salvation is the same for all, but there are distinctions in glory. This distinction is not merited by good works but comes through a sovereign, free, and gracious covenantal disposition of God—a given right to believers merited by Christ.
God thus crowns His own work in order that in such active diversity the glory of His own attributes shines out. All creatures will then live and move and have their being in God, who is all in all, who reflects all of His attributes in the mirror of His works and glorifies Himself in them.”
