My sister Rachel attended the D.C. temple rededication. The baptistry had to be gutted and rebuilt due to mold in the humid environment. She felt the need to do a spiritual rededication or reconsecration of her life. I like the analogy.

Her son's Primary President was helping them prepare white handkerchiefs for the rededication. She explained the dirt and stains show up easily on white. White symbolically shows the need to the Savior's atonement which we need so very much.
