Each of these books are lined up in sequential order and carefully locked away for safe keeping. At any given time, any particular birth can be researched and verified.
There is another, more important "Book of Life," which is carefully preserved, not here on earth, but in heaven.
Revelation 20:12-15Our delivery books are important, and we take great care to record the birth of every baby born in our unit. But it is more important that we know our own names are recorded in the Lord's Book of Life.
Make very sure this day does not wane before you know your name is written there, too.
