Lucifer after the Fall.
"Prince of the power of the air."
The above text shows that he was "created" by the power of God. All the angels were created full grown, and not born as children. Hence this text is describing some heavenly being.
"Thou art the anointed cherub that covereth; and I have set thee so." Verse 14. Lucifer's position was by the throne of God, with his wings outstretched above it.
The ark built by Moses was a type of heavenly things. On the top of this ark were two cherubim with their wings covering the ark where the glory of God rested. See Exodus 25:20. This represents Lucifer's position as covering cherub, close to the throne of God in heaven.
Lucifer was "the anointed cherub." Anciently the prophets of the Lord anointed the kings to show that they were appointed of God to govern and command. Lucifer was, next to the Son of God, the anointed commander of the hosts of heavenly angels.
All his wisdom, beauty, power, and position were given him by God who had created him. The Creator fitted him for the work He wished him to do, and the place He desired him to occupy. Lucifer owed everything which he possessed to his Lord.
But, like some people who have riches and power, he become proud of his glory. He forgot that it was all the gift of God. The text says, "Thine heart was lifted up because of thy beauty." Eze. 28:17.
The Son of God was above him, and equal with His Father. Lucifer was second to Christ; but, considering his beauty and power, he decided that he ought to be equal with God.
The prophet Isaiah says of him, "Thou hast said in thine heart, I will exalt my throne above the stars of God: I will be like the Most High." Chapter 14:13, 14.
