### Only God knows the future
> ““Remember this and stand firm, recall it to mind, you transgressors, remember the former things of old; for I am God, and there is no other; I am God, and there is none like me, declaring the end from the beginning and from ancient times things not yet done, saying, ‘My counsel shall stand, and I will accomplish all my purpose,’”
>
> [Isaiah 46:8-10 ESV](https://bible.com/bible/59/isa.46.10.ESV)
> ““But concerning that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father only.”

> [Matthew 24:36 ESV](https://bible.com/bible/59/mat.24.36.ESV)
### Satan can’t act without permission from God
> “Now there was a day when the sons of God came to present themselves before the Lord, and Satan also came among them. The Lord said to Satan, “From where have you come?” Satan answered the Lord and said, “From going to and fro on the earth, and from walking up and down on it.” And the Lord said to Satan, “Have you considered my servant Job, that there is none like him on the earth, a blameless and upright man, who fears God and turns away from evil?” Then Satan answered the Lord and said, “Does Job fear God for no reason? Have you not put a hedge around him and his house and all that he has, on every side? You have blessed the work of his hands, and his possessions have increased in the land. But stretch out your hand and touch all that he has, and he will curse you to your face.” And the Lord said to Satan, “Behold, all that he has is in your hand. Only against him do not stretch out your hand.” So Satan went out from the presence of the Lord.”

### Fallen angels are under restriction
> “For if God did not spare angels when they sinned, but cast them into hell and committed them to chains of gloomy darkness to be kept until the judgment;”

> [2 Peter 2:4](https://bible.com/bible/59/2pe.2.4.ESV)

### Demons have great knowledge but not omniscience
> “And immediately there was in their synagogue a man with an unclean spirit. And he cried out, “What have you to do with us, Jesus of Nazareth? Have you come to destroy us? I know who you are—the Holy One of God.””

> [Mark 1:23-24 ESV](https://bible.com/bible/59/mrk.1.24.ESV)
Imagine living for thousands of years and having the opportunity to study humans, their actions, their desires. Imagine knowing the scriptures better than humans. They would be able to tell whats on our mind by the tiniest changes in our facial expressions, pupil dilations, breathing patterns, et cetera. Fear not, they are powerless against the armor of God.
### Divination spirits
> “As we were going to the place of prayer, we were met by a slave girl who had a spirit of divination and brought her owners much gain by fortune-telling. She followed Paul and us, crying out, “These men are servants of the Most High God, who proclaim to you the way of salvation.” And this she kept doing for many days. Paul, having become greatly annoyed, turned and said to the spirit, “I command you in the name of Jesus Christ to come out of her.” And it came out that very hour.”

### Satans plans can fail
> “None of the rulers of this age understood this, for if they had, they would not have crucified the Lord of glory.”
>
> [1 Corinthians 2:8 ESV](https://bible.com/bible/59/1co.2.8.ESV)
> “Then Jesus was led up by the Spirit into the wilderness to be tempted by the devil. And after fasting forty days and forty nights, he was hungry. And the tempter came and said to him, “If you are the Son of God, command these stones to become loaves of bread.” But he answered, “It is written, “‘Man shall not live by bread alone, but by every word that comes from the mouth of God.’” Then the devil took him to the holy city and set him on the pinnacle of the temple and said to him, “If you are the Son of God, throw yourself down, for it is written, “‘He will command his angels concerning you,’ and “‘On their hands they will bear you up, lest you strike your foot against a stone.’” Jesus said to him, “Again it is written, ‘You shall not put the Lord your God to the test.’” Again, the devil took him to a very high mountain and showed him all the kingdoms of the world and their glory. And he said to him, “All these I will give you, if you will fall down and worship me.” Then Jesus said to him, “Be gone, Satan! For it is written, “‘You shall worship the Lord your God and him only shall you serve.’””

### Conclusion
Demons have great knowledge, they specialize in human psychology, but they are limited, finite, restricted creatures. They can deceive you into thinking they can see the future but that is just a facade. It’s really just educated guesswork.
