Spirits are men and women. They are very often seen by the natural eye. They have been known to purposefully make themselves visibile to the natural eye. All through the O.T., this is noted. It happens very often today as well. I've seen them. My son related an encounter with a spirit that severely rebuked him when he was a young teenager, sending him home with a sharp rebuke. That rebuke from a tall man (spirit) saved him a great deal of grief.
These spirits (both men and women) are among us as ministering spirits who are the heirs of salvation.
I'd be interested in seeing where a female spirit is seen in the Bible.
