"If you draw that for Grannie Frannie," Emmie told Emma, "we'll put it on the refrigerator, and then she'll save it forever."
Emmie knows this to be true because she knows I have drawings which she and her siblings made as young children. She is aware that those crayon colored pictures are treasured items to me.
Emma drew the picture and it was promptly posted on the gallery of the refrigerator door. After an appropriate time of "showing" I took it down and stored it away in a safe place to keep "forever."
Our Lord is also One who keeps remembrances. The Scriptures tell us that He puts our tears in a bottle and writes them in His book. They also tell us the prayers of all the saints rise up around His throne with the incense of the altar. He remembers His promises to us much more than we could ever try to remember them.
Thankfully though, He also chooses not to remember as well. "And their sins and iniquities will I remember no more," (Hebrews 10:17.)
The most important thing He keeps, is us.
