"Lucifer represents the angel of light with individual intellect who 'rebels' against the outside 'dark authority'. This is why he is called the 'fallen angel.'
The dark and outside authority can be attributed to our flesh and fleshly desires coupled with the outside material world that attempts to take us away from the true light within each one of us. This darkness tries to fool us into looking without when we should have always been looking within the whole time.
Hence, this is the whole illusion of the matrix in which Satan, the true prince of darkness that represents the flesh and free will is looking to control you, so you do not look within yourself for the "prince of light" or "the morning star." - By Moe the Gnostic Warrior
