Book of Life: (Gr. biblos tēs zōēs) In biblical times, cities had a register of names for the citizens living there. (See Ps. 69:28; Isa. 4:3) God, figuratively speaking, has been writing names in the “book of life” “from the foundation of the world.” (Rev. 17:8) Jesus Christ talked about Abel as living “from the foundation of the world,” this would suggest that we are talking about the world of ransomable humankind after the fall. (Lu 11:48-51) Clearly, Abel was the first person to have his name written in the “book of life.” The individuals who have their names written in the “book of Life” do not mean they are predestined to eternal life. This is evident from the fact that they can be ‘blotted out’ of the “book of life.” (Ex 32:32-33; Rev. 3:5) Jesus ransom sacrifice alone gets one written in the “book of life,” if they accept the Son of God. However, it is remaining faith to God that keeps them from being ‘blotted’ out of the “book of life.” (Phil. 2:12; Heb. 10:26-27; Jam. 2:14-26) It is only by remaining faithful until the end that one can be retained permanently in the “book of life.”–Matt. 214:13; Phil. 4:3; Rev. 20:15.
