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. (Malachi 3:16)
Malachi brings a message of hope and comfort to those who are still faithful to the Lord. What a contrast between the iniquitous complainers mentioned above (vs. 13-15) and those who are truly righteous!
A book of remembrance.
The prophet encourages those who are endeavoring to do what is right with the thought that God remembers the devoted service of His people (see on Dan. 7:10).
