Ummm, no. Unless, of course, you mean that if someone attacks them with a spear they can get a spear point in the gut like any other human being. If you attack a real human being with a real spear, the point of the spear will pierce their human flesh. What part of reality don't you understand??

You cannot zap someone from a distance with a force that does not exist, nor can you use a force that does not exist to repel very real attacks with pointy metal weapons.

I mean yeah people do all sorts of ridiculous demos where people stick them with spear points and hit them with swords and whatnot and apparently they don't get hurt. But magicians do this sort of thing all the time. They're just stage tricks. Think about it for a nanosecond. If someone could take a spear point in the gut without any harm, it stands to reason they could take the punch of a heavyweight boxer without harm. So they could let Lennox Lewis hit them with everything he's got, then zap him unconscious with qi. Then they are millions of dollars richer. People could rob banks and deflect the bullets of the police. Now, so far as I'm aware, we're not living in the matrix. Therefore, such feats are not possible.
