Satan was perfect until Sin was found in him11 Moreover the word of the LORD came unto me, saying,
12 Son of man, take up a lamentation upon the king of Tyrus, (Satan) and say unto him, Thus saith the Lord GOD; Thou sealest up the sum, full of wisdom, and perfect in beauty.
13 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.
14 Thou art the anointed cherub that covereth; (Cherub that covereth: Satan, then called Lucifer, was the closest angel to God! He covered the divine presence Although addressing Satan as the covering cherub, the Lord turns to the past tense to describe his action.) 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.
15 Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee.( Satan was created perfect just as were our first parents. God never forces obedience and loyalty. His government is based on love.)
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: (Corrupted wisdom : The person who chooses evil eventually deceives himself. His logic becomes twisted) I will cast thee to the ground, I will lay thee before kings, that they may behold thee.
18 Thou hast defiled thy sanctuaries ( Defiled sanctuaries :Satan's sin corrupted his areas of holiness ) by the multitude of thine iniquities, by the iniquity of thy traffic; therefore will I bring forth a fire from the midst of thee, it shall devour thee, and I will bring thee to ashes ( Reduce you to ashes :Satan's own sin will be the cause of his destruction.) upon the earth in the sight of all them that behold thee.
19 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.
The rebelious Lucifer was created long before Adam and Eve. He rebelled and became the Devil. He and his fallen angels are spirit beings and as such are not subject to death physically, They continue to live on in Eternity and we have no time record of their activities. The Prophets Ezekiel and Isaiah gives us the insight into the Fall of Lucifer and one third of the angels that joined him...... Hell was originally prepared for the Devil and his angels.
