I don’t know about myriads of angels as such, but mystery messengers may be something worth thinking about at least for some. After all the word angel only means messenger. When one hears of the proverbial story of a mother waking up in the middle of the night after dreaming some prescient dream of her son who is distant from her dying, or injured in some specific way and turns out to be so, it raises certain questions that cannot always be dismissed easily as brain chemistry and coincidence, using the word coincidence that is in its conventional way as something that simply coincides that seems significant but explicable in terms of processes that are understood.
Many people report such inexplicable contact or messages, often when a loved family member dies, sometimes without knowing they were ill. Other times in can be in times of danger. To be fair it is not known if so called angels are responsible from the biblical identification such entities are supposed to have. Certainly the meaning of angels being messengers seems to be at odds with the need for myriads of the things if a message is the purpose of such entities. One would seem to be sufficient particularly as time and space don’t seem to be barriers when such phenomena are looked at closely.
In many ways this topic mirrors the debate over the existence of God, which gets rejected on the basis of a rather specific literal interpretation of the bible, even though it is possible to talk about the existence of God without any reference to the bible or any holy book on the basis of other reasons that merit at the very least considered debate.
It is quite possible that such spiritual phenomena has been going on with humanity well before writing was ever invented, in which case the bible only reflects a human interpretation of such things that have been going on since timely memorial. Only those who have experienced such things with sufficient force as to be convinced by them that something radical is going will want comment in the same spirit as I have done, but most here will dismiss the reality of such things which is an end to the debate. For those to whom it isn’t, you’re not alone.
