Hello Carollegalassi. I would like to answer that question,and I would do so with a simple no. No,Satan have many powers,but he cannot read minds. If you would like to,you may see the answer to that question by reading your Bible,if you wish to,go on and read:Jeremias 11 Vers.20,and Chapter 17 vers.10. Psalms 7 Vers 9. and Revelations 2 Vers 23. This is True that only God is the one with such Power to even know what is the greatest Thoughts of Mankind,Thats the reason why I believe Jesus Christ to be God himself,read: Lukes Chapt. 11 Vers.17. You may also read when other Apostles declare with there own tongue that Christ is God himself,read: Gospel of John Chapt.20 Vers 28. and Book of Romans Chapt.9 Vers 5. To understand these things is not so simple like many have thought,but no,Satan does not have that power,if he did then none would ever have a chance to repent and follow God because he wont allow you to do so then.
