What the Spirit of God does in a saint, Satan in a diabolical sense does in a sinner. The Spirit fills the heart with love, joy, holy desires; Satan fills the sinner’s heart with pride, lust, lying. And liek teh drunkard filled with wine, the sinner filled with Satan is not his own man, but an impotent slave.
William Gurnall
