SO TRUE!!! Angels do NOT attempt to deceive in any way - or at least the ones who haven’t FALLEN don’t! It’s actually VERY EASY to ‘test’ an Angel, or a ‘spirit’ or ‘demon’ claiming to be one. AND the FEELING associated with any interaction with a true messenger of God Himself is one that CANNOT be understood unless you’ve actually “been there”. It’s something that really cannot be put into words - at least none I’ve ever found.
I liked your analogy of the soldier or the hit man as well... Sometimes they are a combination of both, if you will. ESPECIALLY if they are relaying a message pertaining to a CHOICE one is being asked to make.
I find no scriptures which directs us to engage speaking to angels. Our conversations are to be with God. Because satan is indeed able to transform himself into an "angel" of light and even satan acknowleges Christ.
Therefor How would we, who are mortal, discern they are an angel to begin with? What do they look like? Please use scripture rather than "feelings" to address this as feelings can and do deceive us.
In old testament times pagan religions were a dime a dozen and with them various entity sightings etc. by those practicing the rites of these religions. We know this can occur for people who have previous occult practices or exposed themselves to them in our day.
In the middle east and india also the orient.. it is a common thing to "see" entities etc. but of course as Christians we understand the religious practices they adhere to would give way to them. These are not angels as they profess that they are, and we also know God directly states not to go thru those who can conjure them up which is either by others who channel or they are themselves taught how to. With the internet many now give lessons as we know.
Additionally God said that as that day approaches there would be things heard and seen which would not be from Him...even though we might believe so....and we are to guard ourselves from these deceptions.
I just cannot see how people who love and know the fullness of Christ can possibly give attention to any entity form claiming whatever they do to an individual. Why would you even consider when we have Christ?
