The word “Messiah” means “anointed,” and “anointed” means “covered/smeared with oil.”
This whole concept is rooted in Jacob laying his head on a rock and and seeing a vision of the stairs to heaven in Genesis 28. To remember the place, he poured oil on the rock, marking the location so he could find it later.
The point is to remember the moment when God opens your eyes to see where heaven and earth meet. Remember the covenant. Remember the vows. Remember the promises.
Remember who you are.
