You have taken account of my wanderings;
Put my tears in Your bottle.
Are they not in Your book?
Then my enemies will turn back in the day when I call;
This I know, that God is for me.
Wanderings and tears are things I've been learning more about recently. I'm glad God has a design for these. If not, I don't know how I'd have hope, how I'd deal with the fact that there's so much I can't make sense of. But He collects my tears in both a bottle and a book: they are at once precious to Him and somehow used to tell His story. It gives David hope for his future when his present was pretty confusing and bleak (he had been seized by Philistines in Gath). It's still true.
But that's not the end for our tears. This is:
Then one of the elders answered, saying to me, “These who are clothed in the white robes, who are they, and where have they come from?” I said to him, “My lord, you know.” And he said to me, “These are the ones who come out of the great tribulation, and they have washed their robes and made them white in the blood of the Lamb. For this reason, they are before the throne of God; and they serve Him day and night in His temple; and He who sits on the throne will spread His tabernacle over them. They will hunger no longer, nor thirst anymore; nor will the sun beat down on them, nor any heat; for the Lamb in the center of the throne will be their shepherd, and will guide them to springs of the water of life; and God will wipe every tear from their eyes.”
