“his deeds from first to last, indeed they are written in the book of the kings of Israel and Judah.”
(2 Chronicles 35:27 NKJV)
The actions of all the ancient kings of Israel were recorded in a book. The actions of the Lord Jesus were recorded in a book. (The four gospels) How much more then will the One who creates history with His spoken Word record all of our individual actions in heavens books. It’s all in the books!
