[1] Bible, New Testament, Epistle of Paul to the Ephesians, chapter 1, 3 to 10; Good News and Elberfelder Translation:
God's plan from the beginning - to sum up everything in Him, literally:
Blessed be our God, the God and Father of our Lord Jesus Christ! [...] Even before He created the world, He [...] destined us to become His sons and daughters. [...] He has indeed made known to us the mystery of His will [...], the plan for the fulfillment of the ages; to gather all things together in the Christ, that which is in the heavens, and that which is on earth - in Him.[1]
