God has a Book of Remembrance
Then those who feared the Lord talked with each other, and the Lord listened and heard. A book of remembrance was written in his presence concerning those who feared the Lord and honored his name. “They will be mine,” says the Lord Almighty, “in the day when I make up my treasured possession. I will spare them, just as in compassion a man spares his son who serves him. And you will again see the distinction between the righteous and the wicked, between those who serve God and those who do not. Malachi 3:16 to 18
You have kept count of my wanderings. Put my tears in your bottle— have not you recorded them in your book? Psalm 56:8
Are they not in thy book? - In thy book of remembrance; are they not numbered and recorded so that they will not be forgotten? This expresses strong confidence that his tears "would" be remembered; that they would not be forgotten. All the tears that we shed "are" remembered by God. If "properly" shed - shed in sorrow, without murmuring or complaining, they will be remembered for our good; if "improperly shed" - if with the spirit of complaining, and with a want of submission to the divine will, they will be remembered against us. But it is not wrong to weep. David wept; the Saviour wept; nature prompts us to weep; and it cannot be wrong to weep if "our" eye "poureth out" its tears "unto God" Job 16:20; that is, if in our sorrow we look to God with submission and with earnest supplication.
