ath, as there is a book of life.

_On the contrary,_ It is said in a gloss upon Ps. 68:29, "Let them be
blotted out of the book of the living," "This book is the knowledge
of God, by which He hath predestined to life those whom He foreknew."

_I answer that,_ The book of life is in God taken in a metaphorical
sense, according to a comparison with human affairs. For it is usual
among men that they who are chosen for any office should be inscribed
in a book; as, for instance, soldiers, or counsellors, who formerly
were called "conscript" fathers. Now it is clear from the preceding
(Q. 23, A. 4) that all the predestined are chosen by God to possess
eternal life. This conscription, therefore, of the predestined is
called the book of life. A thing is said metaphorically to be written
upon the mind of anyone when it is firmly held in the memory,
according to Prov. 3:3: "Forget not My Law, and let thy heart keep My
commandments," and further on, "Write them in the tables of thy
heart." For things are written down in material books to help the
memory. Whence, the knowledge of God, by which He firmly remembers
that He has predestined some to eternal life, is called the book of
life. For as the writing in a book is the sign of things to be done,
so the knowledge of God is a sign in Him of those who are to be
brought to eternal life, according to 2 Tim. 11:19: "The sure
foundation of God standeth firm, having this seal; the Lord knoweth
who are His."

Reply Obj. 1: The book of life may be understood in two senses. In
one sense as the inscription of those who are chosen to life; thus we
now speak of the book of life. In another sense the inscription of
those things which lead us to life may be called the book of life;
and this also is twofold, either as of things to be done; and thus
the Old and New Testament are called a book of life; or of things
already done, and thus that divine energy by which it happens that to
each one his deeds will be recalled to memory, is spoken of as the
book of life. Thus that also may be called the book of war, whether
it contains the names inscribed of those chosen for military service;
or treats of the art of warfare, or relates the deeds of soldiers.

Hence the solution of the Second Objection.

Reply Obj. 3: It is the custom to inscribe, not those who are
rejected, but those who are chosen. Whence there is no book of death
corresponding to reprobation; as the book of life to predestination.
