Well, we got to look at what this entity is claiming. If it agrees with scriptural statements, then if it’s the devil we know too little yet to identify it.
But really some people are impossible to please. You give them exact bible quotes and they call you nuts. You paraphrase to minimize the hackneyed factor and they call you nuts. Maybe their problem is that they don’t want to hear ANYTHING from God except some excuse to say it’s wrong to speak.
Personally, anyone who writes stuff using "I" when pretending to speak for God.. is a nut. Or worse.
