I'm quoting part of the article below and will provide credit and the link for the full article but we have the Bible to turn to also. Credited to Don Stewart and the article is here

@@@@@@@@@@@@@

Fifty-two times in Scripture this being is designated as Satan.

Now it came about on the day when the sons of God came to present themselves before the Lord, that Satan also came among them ( Job 1:6 ).

2. Day-Star

In Isaiah this creature is called the "day star." This has the idea of "bearer of light." This name, translated into Latin, is Lucifer. This was the name of Satan before his fall.

How you are fallen from heaven, O day-star, son of the morning! how you are cut down to the ground, that did lay low the nations!

( Isaiah 14:12 ).

The true "day star" and "bearer of light" is the Lord Jesus Himself.

It is I, Jesus, who sent My angel to you with this testimony for the churches. I am the root and the descendant of David, the bright morning star ( Revelation 22:16 ).

Jesus is the true light.

The true light, which enlightens everyone, was coming 

So I recently wrote a couple songs praising and worshiping the Messiah as we are told to make melodies in our hearts unto the lord. Some of them are based on different biblical concepts of praising and certain subject matters biblical speaking. But the last two had in mind the fallen Angel cherubim Satin. Recently Kirk Cameron was on the Megyn Kelly show talking about his new book which they tried to censor but this book is good because it points out things that be of God for children and he talked about the seven deadly sins which I believe is Catholic doctrine. I don't think the seven deadly sins are a concrete biblical concepts.

Quote

"A common misconception about the seven deadly sins is that they are sins that God will not forgive. The Roman Catholic Church does not teach the sins to be unforgivable; in Catholic doctrine, the seven deadly sins can lead to mortal sins, which will send a person to hell immediately upon death, unless such sins are repented of before death. Catholicism also teaches that the seven deadly sins can be overcome with the seven virtues (humility, gratitude, charity, temperance, chastity, patience, and diligence)."  

Interesting

" Yes, pride, envy, etc., are sins that the Bible condemns; however, they are never called “the seven deadly sins” in the Bible ."

Now then the Angels were created higher than men. They are not men. In other words they're not human and iniquity was found in Satan. Pride and arrogance is wicked although God does forgive humans but Christ told the prostitute go and sin no more. Pride, idolatry and fornication are very wicked. So the prophet Isaiah and Ezekiel including Christ and Apostle Peter spoke about the devil Satin. So here is a little bit of that scripture below. Know your enemy because he is the enemy of your soul.

Ezekiel 28:15 - 18

¹⁵  Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee.

¹⁶  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.

¹⁷   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.

¹⁸  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.

So Eve disobeyed God and so did Adam and so did Satan. But there was a fall and King Solomon understood the whole duty of man is to obey God. There are a lot of religious people in the world but they don't abide in Christ but they may assume/think they do.

1 John 3:10

King James Version

10 In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.

A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.  Jesus Christ

Now in my afterthoughts and after notes God has a will and Satan is a ruler on the Earth but he will be cast out when Christ comes back for a while. He weakens the Nations and he's much more wicked than people could ever imagine. He even tempted our Lord to fall down and worship him. Why is he here and that is a good study. People who are religious and not true believers even deceived do not understand God is very holy and our sins have separated us from him. They can't understand as even the great king Solomon understood that everything is vanity. One of The Commandments is not to make graven images. You're mind is to be on God and his word not on vanity. People fix the outside even painting their face as women with makeup but God looks at the inside being your heart. Is it in right standing with God. Are you arrogant, prideful and evil taking God's name in vain and using that wicked tongue to bless people and then even to curse people. There are people in hell right now that cannot get out because they probably died in their sins. What about you where are you going when you die? When was the last time you read the Bible and you prayed?
