There is a really interesting passage in the Old Testament, which speaks about a certain book called “the book of remembrance;” it reads,
"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. 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. Then shall ye return, and discern between the righteous and the wicked, between him that serveth God and him that serveth him not. For, behold, the day cometh, that shall burn as an oven; and all the proud, yea, and all that do wickedly, shall be stubble: and the day that cometh shall burn them up, saith the Lord of hosts, that it shall leave them neither root nor branch. But unto you that fear my name shall the Sun of righteousness arise with healing in his wings; and ye shall go forth, and grow up as calves of the stall." [Mal 3:16-4:2]
Those who fear The LORD, those who think upon The LORD – each thought is written down for eternity. Think of that! God treasures the thoughts we think toward Him and our fear of Him so much that He writes them down in a book. That ought to make us want to fear Him more and think upon Him more.
And notice who the book is for: it is “for them that feared The LORD, and that thought upon His Name.” That sounds like good reading material. If you fear The LORD and love to think about Him, then this book is for you; if it isn’t for you, then something is wrong with your spiritual life.
Notice also that “The LORD hearkened.” The LORD hears when we speak to each other about Him. Of course He always hears us; for David says “He that planted the ear, shall He not hear?” But here The LORD specifically tells us that He is listening when we talk to each other about Him. There is a special emphasis on it.
And The LORD says “they shall be mine.” We who fear God and whose “meditation of Him shall be sweet” will be a private/special possession of The LORD’s. The KJV says “jewels” but it literally means private possession/property/wealth. As Peter says,
"But ye are a personally elect family; a royal priesthood, an holy nation, a people for His possession; that ye should proclaim the virtue of Him who hath called you out of darkness and into His marvelous light." [1 Pe 2:9]
And as Isaiah says,
"I will greatly rejoice in the LORD, my soul shall be joyful in my God; for he hath clothed me with the garments of salvation, he hath covered me with the robe of righteousness, as a bridegroom decketh himself with ornaments, and as a bride adorneth herself with her jewels." [Isa 61:10]
"Thou shalt also be a crown of glory in the hand of the LORD, and a royal diadem in the hand of thy God. " [Isa 62:3]
We are precious jewels; private possessions for our LORD! He values us that much! That should provoke us to fear Him and think upon Him even more.
Those that fear The LORD and think upon His name and take delight in others who do the same, these are those who will be saved. Malachi tells us, “But unto you that fear My Name shall the Sun of Righteousness arise with healing in His wings; and ye shall go forth, and grow up as calves of the stall.” This is in contrast to those who are proud and do wickedly. They “shall be stubble: and the day that cometh shall burn them up, saith The LORD of Hosts, that it shall leave them neither root nor branch.” So let us fear The LORD and think sweetly upon Him; let us serve Him all the days of our life in love, for He esteems us as special possessions, as jewels.
