Seven Deadly Sins and parasite-demons
We now know that parasites influence their hosts behavior so they can spread and be comfortable in their hosts home. But they never ever enable the host they live in unless it benefits them.
Greed, Lust, Anger, Wrath, Gluttony, Envy, Sloth
All of these desires / emotions / behaviors can be induced by heavily parasites.
From the Gospel of St. Luke
[24] When the unclean spirit is gone out of a man, he walketh through places without water, seeking rest; and not finding, he saith: I will return into my house whence I came out. [25] And when he is come, he findeth it swept and garnished. [26] Then he goeth and taketh with him seven other spirits more wicked than himself, and entering in they dwell there. And the last state of that man becomes worse than the first.
So not only do the parasites influence our behavior, but when we act on the impulses they give us… they multiply. There is no question that demons act through parasites, this is proven in the book of Job. The fact that parasites also effect our mental and physical well-being also tells us they operate on spiritual and mental levels.
This is where the Gospels and Jesus are amazing. Jesus literally teaches us how to live in spite of evil impulses, which often come from parasites. We also are taught how to overcome the demons-parasites. Jesus' 40 days in the desert, he quotes scripture every time temptation came up. Jesus also tells us "It is written, Not in bread alone doth man live, but in every word that proceedeth from the mouth of God." As well as "If any man eat of this bread, he shall live for ever; and the bread that I will give, is my flesh, for the life of the world."
We can call on Jesus and have a top down effect not only on demons, but also on their parasites.
