The study of engineering is on the what-is. The spiritual realm cannot be measured, weighed, experimented on, or any other thing done to it in order to change any aspect of it. I cannot engineer the spiritual realm, as I can the physical one.
I haven’t, but then again perhaps I’ve been scarred in my engineering education by assuming everything we were studying comprised the physical domain and unless the spiritual domain could justifiably integrated into the physical domain, it didn’t exist.
I'm not sure that your studies were complete. Engineering is not about defining reality and non reality. It is about developing principles and practices that work. There are many things that engineering ignores because they have no practical use. Yet there are many things that engineering has only borderline basic knowledge of (e.g. how concrete works), but use extensively simply because we have found out that it does work in certain ways under certain conditions.
Yet, I also know from faith in Christ and from experience, that domain is very real. I am not appealing to experience for its justification, but I would have to deny real experience to ignore the spiritual domain.
Okay. Faith is belief; experience may lead to knowledge, sure.
I also know some spiritual persons, with very real character and perception, and volition, can effect physical force by their choosing, while not fully perceptible to us in all our senses.
If they can, for instance, lessen the mass of a glass of water or a rock while that object is sitting on a weigh scale, then they should have no problem duplicating it in front of the cameras and witnesses.
IMHO, I suspect it might be a leap of justification to conclude these “aliens” are fallen angels, but such an identification is consistent with many reports of their behavior and circumstances surrounding experiences of them.
It is conjecture only at this point. A flight of fancy, as it were.
Try it. You might be surprised at what God gives us when we have been regenerated. The trick, just like in our physical moments prior to the first death, is to remain in faith through Christ in all things. He controls the rest.
If they can, for instance, lessen the mass of a glass of water or a rock while that object is sitting on a weigh scale, then they should have no problem duplicating it in front of the cameras and witnesses.
Even if they did, most people still wouldn't believe it anymore than they have any belief in the reports of what miracles occurred by God for Moses. Additionally, why should they when they aren't here to answer our whims. Lack of evidence by our standards doesn't eliminate their existence any more than atheists can remove the existence of God.
