Hello Trisha,
As I'm sure you know, there is a spirit realm and there are spirit beings in the spirit realm. According to the bible, there are three heavens. Satan was kicked out of heaven. There is also a spirit realm down here where we reside on the earth. There are angels and there are demons in the spirit realm on this level. People who say they are talking to the dead or seeing the dead are actually seeing familiar spirits. Meaning, these are evil spirits (demons) that are familiar with people who passed on. Spirits can change their appearance.
2 Corinthians 11:14 KJV
And no marvel; for Satan himself is transformed into an angel of light.
Acts 16:16And it came to pass, as we went to prayer, a certain damsel possessed with a spirit of
divination met us, which brought her masters much gain by soothsaying:
The (demon) spirit of divination operates through phyics.
In the bible, people went to the prophets or seers to find something or someone who was lost. See the scriptures below:
1 Samuel 9:3-6, 9, 18-20
3And the asses of Kish Saul's father were lost. And Kish said to Saul his son, Take now one of the servants with thee, and arise, go seek the asses. 4And he passed through mount Ephraim, and passed through the land of Shalisha, but they found them not: then they passed through the land of Shalim, and there they were not: and he passed through the land of the Benjamites, but they found them not. 5And when they were come to the land of Zuph, Saul said to his servant that was with him, Come, and let us return; lest my father leave caring for the asses, and take thought for us. 6And he said unto him, Behold now, there is in this city a man of God, and he is an honourable man; all that he saith cometh surely to pass: now let us go thither; peradventure he can shew us our way that we should go.
9(Beforetime in Israel, when a man went to enquire of God, thus he spake, Come, and let us go to the seer: for he that is now called a Prophet was beforetime called a Seer.)
18Then Saul drew near to Samuel in the gate, and said, Tell me, I pray thee, where the seer's house is. 19And Samuel answered Saul, and said, I am the seer: go up before me unto the high place; for ye shall eat with me to day, and to morrow I will let thee go, and will tell thee all that is in thine heart. 20And as for thine asses that were lost three days ago, set not thy mind on them; for they are found.
If you go to a Holy prophet or seer for this information, you are getting this information from the God. If one goes to those who call themselves seers or phyics, etc. and they are not God's Holy prophets or seers; then that information is coming from demons.
