TNDL: "THE KNOWLEDGE OF SATAN, LUCIFER THE DEVIL, THE DESTROYER WHO TAKES LIFE, BUT CANNOT GIVE ETERNAL LIFE!"

Satan and the origin of evil
In the Bible, especially the New Testament, Satan (the Devil) comes to appear as the representative of evil. Enlightenment thinkers endeavoured to push the figure of the Devil out of Christian consciousness as being a product of the fantasy of the Middle Ages. It is precisely in this figure, however, that some aspects of the ways God deals with evil are especially evident. The Devil first appears as an independent figure alongside God in the Hebrew Scriptures. There evil is still brought into a direct relationship with God. Even evil, insofar as it has power and life, is effected by God: “I form light and create darkness, I make weal and create woe, I am the Lord, who do all these things” (Isaiah 45:7).
Satan tests Job
In the Book of Job, Satan appears as the partner of God, who on behalf of God puts the righteous one to the test. Only in postbiblical Judaism does the Devil become the adversary of God, the prince of angels, who, created by God and placed at the head of the angelic hosts, entices some of the angels into revolt against God. In punishment for his rebellion, he is cast from heaven together with his mutinous entourage, which were transformed into demons. As ruler over the fallen angels, he continues the struggle against the kingdom of God by seeking to seduce humans into sin, by trying to disrupt God’s plan for salvation, and by appearing before God as a slanderer and accuser of saints, so as to reduce the number of those chosen for the kingdom of God.
Thus, Satan is a creature of God, who has his being and essence from God; he is the partner of God in the drama of the history of salvation; and he is the rival of God, who fights against God’s plan of salvation. Through the influence of the dualistic thinking of Zoroastrian religion during the Babylonian Exile (586–538 BC) in Persia, Satan took on features of a countergod in late Judaism. In the writings of the Qumrān sects (who preserved the Dead Sea Scrolls), Belial, the “angel of darkness” and the “spirit of wickedness,” appears as the adversary of the “prince of luminaries” and the “spirit of truth.” The conclusion of the history of salvation is the eschatological battle of the prince of luminaries against Belial, which ends with judgment upon him, his angels, and people subject to him and ushers in the cessation of “worry, groaning, and wickedness” and the beginning of the rule of “truth.”
