If Satan lied to me about his origins, what would be the point in telling me a fictitious story about being born a Hindu priest prior to becoming the Devil?
Because he doesn't want to say the truth--He was beautiful beyond description, he was arrayed in magnificent jewels, he held a very high position in the kingdom of God, he had as truly beautiful, magnificent voice---- he became vain, thought only of himself, he took his eyes of God and put them on himself to the point he forgot he was a created creature and wanted to be God and became jealous and dissatisfied with his lofty position and wanted more than he had any right to. So he lied and led others astray and turned himself into that loathsome creature known as Satan --because he doesn't want to admit the truth--
Eze 28:13 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.
Eze 28:14 Thou art the anointed cherub that covereth; 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.
Eze_28:15 Thou wast perfect in thy ways
from the day that thou wast created, till iniquity was found in thee.
and because he knows this is what waits for him:
Rev 20:2 And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years,
Rev 20:3 And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.
Rev 20:9 And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.
Rev 20:10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
Mat 25:41 Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire,
prepared for the devil and his angels:
He was no human, no Hindu priest
Joh_8:44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
