Paul compares God's wonderful actions here to great "riches." AT: "his glory, which is of great value, upon" (See: [[rc://en/ta/man/translate/figs-metaphor]])
Here "glory" refers to life in heaven with God. AT: "whom he prepared ahead of time in order that they might live with him" (See: [[rc://en/ta/man/translate/figs-explicit]])
Here "called" means God has appointed or chosen people to be his children, to be his servants and proclaimers of his message of salvation through Jesus.
