“Submit yourselves therefore to God. Resist the devil, and he will flee from you.“ James 4:7
In the time of attacks by Satan, have you ever resisted the devil with your mind (never speaking aloud) and then the attack stopped?
If Satan does not have access to your mind - how would he know that you resisted him?
Contrary to the teaching of Mrs. White, Satan does have access to our minds. That is why deaf-mutes and paralyzed people can successfully resist the devil with their minds - not speaking aloud.
