In 1 Samuel 16:14-16 we see the contrast between the Spirit of the LORD leaving Saul and an evil spirit being sent by God instead to torment him:
14 But the Spirit of the LORD departed from Saul, and an evil spirit from the Lord troubled him.
15 And Saul's servants said unto him, Behold now, an evil spirit from God troubleth thee.
16 Let our lord now command thy servants, which are before thee, to seek out a man, who is a cunning player on an harp: and it shall come to pass, when the evil spirit from God is upon thee, that he shall play with his hand, and thou shalt be well.
[1 Samuel 16:14-16, KJV]
However, Matthew 12:43-45 reveals that evil spirits have minds and make willful decisions of their own:
43 When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest, and findeth none.
44 Then he saith, I will return into my house from whence I came out; and when he is come, he findeth it empty, swept, and garnished.
45 Then goeth he, and taketh with himself seven other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is worse than the first. Even so shall it be also unto this wicked generation.
[Matthew 12:43-45, KJV]
Other examples of evil spirits showing evidence of personhood are:
15 And the evil spirit answered and said, Jesus I know, and Paul I know; but who are ye? [Acts 19:15, KJV]
7 And cried with a loud voice, and said, What have I to do with thee, Jesus, thou Son of the most high God? I adjure thee by God, that thou torment me not. 8 For he said unto him, Come out of the man, thou unclean spirit. 9 And he asked him, What is thy name? And he answered, saying, My name is Legion: for we are many. [Mark 5:7-9, KJV]
Question: If evil spirits have personhood, does this mean that the Holy Spirit of God also has personhood? More generally, is it an inherent property of all spirit beings (evil or otherwise) to have personhood? Is there such a thing as an unconscious, mindless and lifeless spirit?
