The following is given in a Bible Study/notes format.
You may wish follow the Spiritual Warfare general outline.
A. Where did he come from?
Genesis 1:1, Exodus 20:11, Nehemiah 9:6, Colossians 1:16
First, we should see that God was in the beginning, not Satan. Second, we should see that God made everything, not Satan. Third, we should see that God made Satan.
Which is greater? The Creator or the creation???
"Son of man, take up a lamentation upon the king of Tyrus, and say unto him, Thus saith the Lord GOD; Thou sealest up the sum, full of wisdom, and perfect in beauty. Thou hast been in Eden the garden of God; every precious stone was thy covering, the sardius, topaz, and the diamond, the beryl, the onyx, and the jasper, the sapphire, the emerald, and the carbuncle, and gold: the workmanship of thy tabrets and of thy pipes was prepared in thee in the day that thou wast created. Thou art the anointed cherub that covereth; and I have set thee so: thou wast upon the holy mountain of God; thou hast walked up and down in the midst of the stones of fire. Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee. By the multitude of thy merchandise they have filled the midst of thee with violence, and thou hast sinned: therefore I will cast thee as profane out of the mountain of God: and I will destroy thee, O covering cherub, from the midst of the stones of fire. Thine heart was lifted up because of thy beauty, thou hast corrupted thy wisdom by reason of thy brightness: I will cast thee to the ground, I will lay thee before kings, that they may behold thee. Thou hast defiled thy sanctuaries by the multitude of thine iniquities, by the iniquity of thy traffick; therefore will I bring forth a fire from the midst of thee, it shall devour thee, and I will bring thee to ashes upon the earth in the sight of all them that behold thee. All they that know thee among the people shall be astonished at thee: thou shalt be a terror, and never shalt thou be any more" (Ezekiel 28:12-19)
Ezekiel speaks in this passage of the king of Tyrus. However, the passage has a double meaning. It describes the literal king of Tyrus, but also describes Satan. God, the creator made (literally "set") Satan to be full of wisdom and perfect in beauty. He was complete. God also set him in the garden of Eden. This points back to Satan's origin (see Genesis 3:1).
God covered him with every precious stone. Actually this list is the same as for the stones on the apparel of the high priest with the exception of three stones. The gold is specifically representative of kingly apparel. The Mercy Seat in the temple was made of pure gold. The idea of "workmanship" indicates that God made Satan for a specific service. Satan had tabrets (timbrels) and pipes (flute or horn) built into his body. The idea of "prepared" indicates these were designed by God with a specific purpose. Satan was to use these to lead the heavenly hosts in worship of God. God designed music for the purpose of worship. Satan was Heaven's worship leader.
Satan was the anointed cherub that covered. The concept of "anointed" meant to be set apart for service unto God (see Exodus 30:26). The concept of "covered" may be compared to Isaiah 6:1-3 and Exodus 25:20. God said, "I have set thee so." Please notice who is in charge. God said that Satan was upon the holy mountain of God. This was the place set apart or exalted for God. Satan was in the presence of God walking up and down in the middle of the stone of fire. What an awesome sight!
Satan was perfect in his ways, his thoughts and actions from his time God created him. Then iniquity was found in him. The word "iniquity" means perverseness. The God bluntly says that Satan has sinned. Note God's word, "I will cast thee as profane out of the mountain of God." God is still in control. God said, "I will destroy thee." Why? Satan began to look at his beauty and focus his attention on himself. Once he had seen from God's perspective (true wisdom), but now that wisdom has become darkened as he looks at himself.
"How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations! For thou hast said in thine heart, I will ascend into heaven I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north: I will ascend above the heights of the clouds; I will be like the most High" (Isaiah 14:12-14).
Lucifer is the original name given to the devil. The term "Lucifer" means the "shinning one". This is interesting because we can see that God created Lucifer (Satan) to reflect God's glory. However, now he only appears as an angel of light, but is the angel of darkness.
There are five "I will's" listed. This is the indication of pride,
being boastful, and foolish. Lucifer assumed authority in
contrast to receiving God's delegated authority.
2. "I will exalt my throne above the stars of God" = this may indicate taking authority over the angels (Job 38:7).
3. "I will sit also upon the mount of the congregation = this may refer to the temple (Daniel 11:37, II Thessalonians 2:4).
4. I will ascend above the heights of the clouds (literally "cloud") = the cloud may be a covering of God (Exodus 13:21).
5. I will be like the most high = he assumed to take the place of God.
Who is the speaker? Who is still in control? It is God! God will bring judgment upon Satan. When Satan's judgment is revealed people will marvel, not at his power, but the deceptiveness in appearing to have power.

Strategy of Satan
List: (thought question)
Note: On various occasions, I have seen people who said that they could not make a decision for Christ because they were too confused. After a spirit of confusion or fear was bound, the individuals readily made the decision to commit their lives to Christ.
Note: Satan tries to get people to believe that they must work for their salvation even after them have committed their lives to Jesus and are saved. I often counsel people who have come to believe that they must live up to a certain standard in order to keep their salvation. This is a trap. They will fall and when they fall, Satan lays a guilt trip on them, trying to keep them from returning to grace.

Discerning of evil spirits
Please read Job 4:12-21. Many people assume that the spirit was from God without testing the spirit. However, we are to test the spirits. Now looking at the spirit that came to the friend of Job, we find  the spirit appealed to his desire for special revelation (verse 12). This is what the serpent did with Eve in the Garden when he said, "You will become as gods, knowing good and evil."  The spirit came in the night, evidently the form of a nightmare (verse 13).  The approach of the spirit was intimidation (verses 14-15). Fear is not God's approach to Believers. God does not give us a spirit of fear, but of power, love, and a sound mind. Whenever people were fearful of angels, the angels said, "Fear not."  There is an obscurity of the form (verse 16). We do not find obscurity in the appearance of angels in Scripture.  The message begins with an accusation. Who is the accuser, but Satan?  Does God trust His servants (verse 18)? God often entrusted his Word to His angels. Why was this spirit so sensitive about God charging some of His angels with folly? This was one of the angels that rebelled with Satan. It is no wonder that this evil spirit was bitter and carried a grudge against God.  Does God trust man with anything (verse 19)? Yes! He has trusted His Church to carry His precious Gospel into all the world.  Is man destroyed without God caring about him (verse 20)? Look at the hopeless implications. God, however, keeps record of the sparrows that falls and the deaths of His saints are precious in His sight.  Is life upon this earth futile and without purpose as this spirit would have us believe (verse 21)? The obvious answer is, "No!" We have a purpose to serve the Lord. Furthermore, God works all things together for our good.

H. Where are the Open doors?
Doors Leading To Strongholds
2. The enemy is like a wild animal, crouched, ready to spring into an opening.
3. A couple examples of the open doors are "anger" and "occult involvement".
Back door = sin
Front door = mental / emotional
2. We are permitted angry for one day, but not for two.
3. If we are angry for more than one day, we open a door up for the enemy to take control of one or more areas of our lives.
2. Evil spirits are described here as the "tormentors".
3. God is described as "the king" (Matthew 18:21-35) who is willing to forgive us.

5. When we hold unforgiveness toward our fellow man, God turns us over to the tormentors (evil spirits) to harass, control, and hurt us.
6. Unforgiveness may lead to bitterness, rage, revenge, guilt, depression, and even to suicide. (misery loves company).
Any kind of occult involvement opens the door
