Jesus said my sheep know my voice. I assume His sheep also know Satan’s voice as well. Virtually every Christian I know also cannot stand to listen to Obama. I think Christ granted His sheep immunity to such deceit.
John 10:4-5
And when he [the Good Shepherd] brings out his own sheep, he goes before them; and the sheep follow him, for they know his voice. Yet they will by no means follow a stranger, but will flee from him, for they do not know the voice of strangers.
