A Book Of Remembrance

Mal 3:16 Then they that feared the LORD spake often one to another: and the LORD hearkened, and heard it, and a book of remembrance was written before him for them that feared the LORD, and that thought upon his name.
Mal 3:17 And they shall be mine, saith the LORD of hosts, in that day when I make up my jewels; and I will spare them, as a man spareth his own son that serveth him.
Mal 3:18 Then shall ye return, and discern between the righteous and the wicked, between him that serveth God and him that serveth him not.
