All the horrors and suffering that come with the seventh trumpet (for it is the third woe, Revelation 11:14) shall not upset God’s promise to protect his own and bring them safely to the New Jerusalem. Precisely how God would protect and preserve may remain a mystery (= as yet unclear), but this promise as voiced through the prophets of old will certainly come to pass.
7 mais qu'aux jours de la voix du septième ange, quand il sonnerait de la trompette, le mystère de Dieu s'accomplirait, comme il l'a annoncé à ses serviteurs, les prophètes.
