You may have heard someone ask this question, or you may have asked it yourself--

This is a good question, and there are probably things the Holy Ghost can do as a spirit that we don’t know much about, and I think we need more revelation on how it is done, but I can share a metaphor that has satisfied me so far so that I have faith that he is with worthy members, each and all.

When I was in high school, we got to go see a laser light show.  At the beginning, they showed us a single green dot on the screen and explained this was the only laser they used.  They moved the dot back and forth slowly in a line, then faster and faster until the path of the dot blurred together and appeared to become a solid line.  To our perception that single dot was everywhere on the line at once.  Then they took that line and began to form it into all kinds of curving shapes and designs that morphed from one thing to the next, and the whole show consisted of this kind of thing set to music.  As I considered that all of that laser animation was made of a green dot moving faster than my eye could follow, my brain just about exploded.

Perhaps the Holy Ghost moves among us faster than we can detect.  Yes, this is speculation, and the mechanics by which the Holy Ghost can be simultaneously with us may be something different, but this metaphor helps me have faith that the promise about having the presence of the Holy Ghost can be fulfilled.  If a laser dot can seem to be everywhere in a line, it’s definitely a cinch for the Holy Ghost to be everywhere the members are.
