The scriptures read are Ezekiel 47-48, Psalm 91 and Revelation 15.
Ezekiel 47-48. Ezekiel's vision of the restored temple and land of Israel continues. The river coming from under the temple and flowing East seems to be a symbol of life. It will restore parched lands, be filled with fish and be flanked by fruit trees.
The 12 tribes will be given new allotments. And the new name of Jerusalem will be "The Lord is There," because his presence will return with the new temple.
Psalm 91. A breathless rock version of this psalm.
Revelation 15. We are in liturgical mode. There are songs and the temple opens and robed angels carry golden bowls, such as were used to pouring out libations. But they contain God's wrath, his anger at the sins of the world.
(H) The singers who triumphed over the beast are those who stood fast in the face of Papal corruption and persecution. (P) The singers are martyrs and the "seven last plagues" are those that hit Jerusalem when they revolted against Rome. (F) The singers are those who converted after the Rapture and during the Tribulation period and were subsequently martyred (since they are in heaven). (S) The seven last plagues must come very close to the end of the world. Couldn't find any reference to what the Spiritual school thinks of the singers.
The scene is set for the last seven plagues.
