I mention in my Blog on 'The UFO 'Aliens" Demon Connection' how in some of these so-called alien encounters, these beings recoil and flee to the utterence of Jesus name.
(As with demonic/evil spirits.) But I wanted to go into more detail why this would work at all, when it has also worked universally for other people with different faith and beleif systems beyond Christian.

So here I am going to try to explain this universally, so all faith and belief systems might understand this:

Jesus, to Christian is the 'Son of God', 'The redeemer', 'The Savior'. His Hierarchy is more so where Christian rank him high as God's son.

People have to understand, Jesus was a real person who lived on this earth 2000 years ago. And regardless of your belief as to this 'rank' and 'relation' in the after life, he is a REAL spirit, a poweful 'positive' spirit whom the negative entities fear and hate.

I have been around long enough to find using Jesus name, and not just by Christians, DOES in fact have a reaction on these spirits. Of course more so when you have faith. Which is psychologically is a sort of 'positive thinking', and 'confidence'. Remember 'positive', everything positive will affect these evil entities to a degree. positive attitude, music, thinking, objects, words, etc.)
And invoke the name of Jesus, is asking for a 'positive' spirit to ward off a 'negative' one.

Using the name of Jesus alone, is often all people can remember to do in a panic. Where they forget any and all prayers when in the presence of an evil one. The intense fear that comes with such an encounter may even affect the person where they can't recite their own address even.
But we know simply saying 'Jesus' name alone has released them from paralysis, attack, or brought a stop to poltergeist activity in the room for example.

This isn't in saying that it will alone always help. Just that people should understand the significance of JESUS as a positive spirit, and why it make work for non-Christians as well.
