If approved at his master’s coming (evidently from some trip), the slave would be rewarded by being placed over all the master’s belongings.​—Mt 24:3, 45-51.

Those who make up the faithful slave will receive expanded responsibility if they are found faithful at the master’s promised coming. When they receive their heavenly reward and become corulers with Christ, he will appoint them over “all his belongings.” Along with the rest of the 144,000, they will share Christ’s vast heavenly authority.​—Mt 24:46, 47; Lu 12:43, 44.
