Isaías 4:3

He that is left in Zion... — The prophet turns from the Jerusalem that then was, with the hypocrisies and crimes of the men and the harlot fashions of its women, to the vision of a new Jerusalem, which shall realise the ideal of Psalms 15, 24. There every one should be called “holy” (comp. 1 Coríntios 1:2; 2 Coríntios 1:1), and the name should be no unreal mockery (Isaías 32:5), but should express the self-consecration and purity of its inhabitants.

Every one that is written among the living. — Literally, for life. The idea is that of “the book” or “register” of life in which are written the names of those who are worthy of living in the heavenly city. It meets us as early as Êxodo 32:32, and appears in Salmos 56:8; Salmos 69:28; Ezequiel 13:9.; Malaquias 3:16; Daniel 12:1; Acts xiii 48; Filipenses 4:3; Apocalipse 3:5; Apocalipse 13:8; Apocalipse 21:27. An examination of the passages, especially the first, will show that while it involves the idea of an election, it excludes that of an irreversible predestination, and that the election has to be “made sure” by a life in harmony with it. (2 Pedro 1:10.)
