The devil may have learn to mimic God’s voice.
After all, he was in the presence of God
Read Job 1:7-8, Job 2:2-3
We would have to learn to discern between the still small voice of God, my sub conscious voice, or the devil’s voice.
The devil’s voice properly stings and does not sit well in the spirit, because they sting.
Ephesians 6:16
Lift up over all the [covering] shield of saving faith, upon which you can quench all the flaming missiles of the wicked [one].
The devil is properly adept at quoting the Bible to throw us off course too.
He did that to Jesus too, in Matthew 4
For example, “you have failed again”
“if a man doesn’t rule his household well, how can he be entrusted?’
“Who do you think you are?”
“You are lousy”
It’s time to take up the shield of faith 
I hope you are blessed.
