Apocalypse Revealed #588
588. 13:8 All who dwell on the earth will worship it, all whose names have not been written in the Book of Life of the Lamb. This symbolically means that all in the Protestant Reformed Church acknowledged that heresy, meant by the dragon and the beast, as a sacred tenet of the church, all but those who believed in the Lord.
To worship means, symbolically, to acknowledge as a sacred tenet of the church, as in nos. 579, 580 above. All who dwell on the earth symbolize all in the Protestant Reformed Church, as in no. 558. Names not written in the Book of Life of the Lamb means, symbolically, all but those who believe in the Lord. Names symbolize people in respect to their character (nos. 81, 122, 165). The Book of Life symbolizes the Word of the Lord and all doctrine regarding Him (nos. 256, 257, 259, 469). And because all of the church's doctrine from the Word has relation to people's believing in the Lord, therefore this is here meant by having a name written in the Book of Life of the Lamb.
