Extracts and comments from Revelation Chps. 3 and 13.
He that (a)overcometh, thus shall be clothed in (b)white raiment; and I will not blot out his name out of the (c)Book of Life, and I will confess his name before My Father, and before His (d)angels.
(c) Book of Life; One only, The Lamb’s, from the “foundation” of the world, (Rev. 13:8, 17.8, 20:12, 20:15, 21:27 & 22:19). Also (Dan. 12:1, Ex. 32:32-33, Psm. 69:18, Isa. 4:3, Ezk. 13:9 & Luke 10:20). The word “foundation”, should be translated "overthrow", see comments on these references.
See: 'The Book of Life':
And all that dwell upon the Earth shall (a)worship him every one whose name is not written in the (b)Book of the Life of the Lamb slain, from the foundation of the world.
(b) "Book of the Life of the Lamb slain, from the foundation of the world". The word "foundation" in Greek is "Katabole", which means "overthrow". This seems to have occurred at some stage between Gen. 1:1, and Gen. 1:2, see: The Age of the Earth Controversy: No information is given as to the reason, but is implicit in Almighty God's Plan of Redemption in Christ, as the Lamb's Book of Life started after that event! Much clarity is given by Paul and Peter regarding this juncture point. It is clear from Eph. 1:4, and 1 Peter 1:20 that some are "known," before the "overthrow", some after. Only Christ and His Body as shown in Eph. 1:4 and 1Peter 1:20 are "known" before the overthrow (foundation). Those after are the Jew, and other groups, i.e. perhaps Christendom (religious but not of the Body of Christ), Overcomers of Revelation, and all who must eventually stand before the Great White Throne for Judgement. Here those after are referred to. Those before are possibly/ probably, in the opinion of the writers, no longer on Earth as mentioned earlier, (see Chp. 8:1(a), last para.). Some opinions are that The Lamb's Book of Life started before the overthrow/foundation, which however is not the writers view, as that does not concur with Scripture's statements, (see ref. Rev. 3:5(c)). What is clear is that The Lamb's Blood is retrospective from the overthrow/foundation, and that there are two groupings, those known before and those after.
