SHARI - Can Satan read your mind? I learned in seminary that Satan does not have the ability to read your mind.

JOEL - This idea comes from the following scripture:

"there is none else save God that knowest thy thoughts and the intents of thy heart." (D&C 6:16)

Satan certainly does not know the mind of God (Moses 4:6) and according to the above scripture probably does not have the ability to read our minds either, but he certainly can place evil thoughts in them if we allow it. The scriptures tell us:

"For behold, at that day shall he(Satan) rage in the hearts of the children of men, and stir them up to anger against that which is good." (2 Nephi 28:20,22)

Regardless of whether he can know our thoughts or not, we do know he can in some way determine our susceptibility to a particular temptation from our words and actions, which reveal our thoughts.
