Dementors and the Devil

     Lupin's description of Dementors is found on page 140: "Dementors are among the foulest creatures that walk this earth. They infest the darkest, filthiest places, they glory in decay and despair, they drain peace, hope and happiness out of the air around them. Even Muggles feel their presence, though the can't see them. Get too near a Dementor and every good feeling, every happy memory, will be sucked out of you. If it can, the Dementor will feed on you long enough to reduce you to something like itself - soulless and evil. You will be left with nothing but the worst experiences of you life."
     I think that this description of the way Dementors work is also a great description of the way the devil works. To illustrate my point I'm going to match bits of scripture with pieces of Lupin's description (or other well known facts regarding Dementors). The difference between the two descriptions is largely do to the fact that the Devil's attributes are described while the Dementor's actions are described and that the Devil has a much clever disguise but for the most part the are the same because they both represent/are evil in it's purest form. (In this entry muggles=unbelievers and wizards=followers of Jesus because wizards have the power to fight off the dementors and followers of Jesus have the power (through Him) to fight of the Satan.)

Bible	Dementors	Explanation
Satan's ultimate goal is our destruction. (1 Peter 5:8; John 10:10)	Dementors want to feed on you until you become soulless and evil.	Dementors and Satan are both throughly evil and their goal is to make others evil too because that is the only way to completely destroy a person.
Satan is a liar. (John 8:44)	Dementors leave you with nothing but the worst experiences of you life.	Satan lies in a variety of ways, many of which you've probably experienced, while Dementors tell only one lie that's very powerful. They lie to you by making you feel like nothing good has ever happened in you life.
Satan prevents unbelievers from seeing God and His light/hope (and because God is all things good, he is also preventing them from seeing good). 2 Cor. 4:4	Dementors suck every good feeling and happy memory out of you.	Dementors and the Devil try to stop you from recognizing the happiness in your life. Dementors suck out all happiness from you so you feel like life is just a miserable waste, especially for muggles because they are blind to the cause. Satan does the same thing by creating a empty, pointless feeling in people who don't know God and they can't fight it because they are unaware of the cause.
Jesus has made us aware of Satan's plans and trickery which allows us to fight him through Jesus. (2 Corinthians 2:11)	Only Wizards can fight Dementors because they can produce patronuses while muggles can't. (and the can see Dementors)	Only believers have the power to successfully fight Satan because we are the only ones who have Jesus and recognize Satan. Jesus has shown us how to recognize Satan's trickery and will fight him for us if we ask. In the same way, only wizards have the power to produce a patronuses (light warriors) and they alone can recognize dementors and their effects/ways.
Satan often pretends to be something good in order to trap/trick us but if we look a little closer and remain in God we can recognize if something is good or evil. (2 Cor. 11:14)	For a while, Wizards used Dementors as guards, ignoring the fact that dementors where evil because they thought they would benefit from them. This resulted in a mass breakout from Azkaban.	Both Satan and Dementors like to role play. They pretend to be something good and helpful but their nature never changes. While a certain TV show or party may look appealing and "not bad", we must learn to recognize that if God isn't in, Satan can use it against us/God (Matt. 12:30). Things that look good in the beginning will reveal their true colors when it's too late, just like the Dementors did when Voldemort came back.

Those are the ones that came to mind for me immediately but if anyone has anymore please leave them in the comments below! thanks! :)

p.s. another connection is that the dementors have no eyes and are, therefore, blind to the beauty of a patronus, the only feel it's power. That is the same way with evil beings, they have blinded themselves to God's beauty but can't help feeling his power!
