Can the devil read our minds?

No. First Kings 8:39 says that God alone knows every human heart. There is no one else who has that ability. God knows what we will say before we can say it, while the thought is still formulating (Psalm 139:4). Jesus, being God incarnate, exhibited the divine quality of knowing men’s thoughts: “He knew what was in each person” (John 2:25; cf. Matthew 9:4; John 6:64).

The Bible does teach us that Satan is powerful. Likely he was the highest of all the fallen angels, as he was persuasive enough to convince one third of the angels to join him in his rebellion (Revelation 12:4). Even after his fall, not even Michael the archangel dared to confront him without the Lord’s help (Jude 9). Satan is the “the ruler of the kingdom of the air, the spirit who is now at work in those who are disobedient” (Ephesians 2:2b). However, Satan’s power has its limits, and reading our minds seems to be beyond his ability.

For Satan and his demons to read our minds would take omniscience, which they do not have. God is the only One who can know our thoughts. However, Satan and his demons have been observing and tempting human beings for thousands of years. In addition, they can overhear our speech when we talk to others (and to ourselves!). Surely, they have learned a few things about us over the years. Even without the ability to know our thoughts, they can make a well-educated guess as to what we are thinking and then attempt to use that to their advantage. That is why we are commanded to “submit yourselves, then, to God” (James 4:7a), before we are told to “resist the devil” (James 4:7b).

No but he can tell what we like and what we think based on our speech and our actions. The devil is a very intelligent invisible spirit that watches humans all the time . He listens to what we talk about to learn us better. He also watch our activity to learn the things we like and dislike. Then with this information he manipulates us to do sinful things.

I don't know what the universe is called, but in Mormonism their is a star system called the Kokaubeum

No but I can and then I tell the devil what you were thinking when we have tea.

Of course. The entire spiritual realm knows all you are thinking and doing.

Nope. No such creature.
