411. The Lord states many times in the Prophets that the final point of vastation must come before a new Church can arise. He there uses the term vastation for things which have regard to the celestial things of faith, and desolation for those which have regard to the spiritual things of faith. He also refers to consummation and destruction, as in Isaiah 6:9, 11-12; 24; 33:8 and following verses; 42:15-18; Jeremiah 25; Daniel 8; 9:24-end; Zephaniah 1; Deuteronomy 32; Revelation 15; 16; and following chapters.
