John 8:44 The devil 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.
[The Great controversy pp 495>496] Leaving his place in the immediate presence of God, Lucifer went forth to diffuse the spirit of discontent among the angels. Working with mysterious secrecy, and for a time concealing his real purpose under an appearance of reverence for God, he endeavored to excite dissatisfaction concerning the laws that governed heavenly beings, intimating that they imposed an unnecessary restraint.
Since their natures were holy, he urged that the angels should obey the dictates of their own will. He sought to create sympathy for himself, by representing that God had dealt unjustly with him in bestowing supreme honor upon Christ. He claimed that in aspiring to greater power and honor he was not aiming at self-exaltation, but was seeking to secure liberty for all the inhabitants of Heaven, that by this means they might attain to a higher state of existence.
God, in his great mercy, bore long with Lucifer. He was not immediately degraded from his exalted station when he first indulged the spirit of discontent, nor even when he began to present his false claims before the loyal angels. Long was he retained in Heaven. Again and again he was offered pardon, on condition of repentance and submission. Such efforts as only infinite love and wisdom could devise, were made to convince him of his error.
1st John 1:8 If we say that we have no sin, we deceive ourselves, and the truth is not in us. 10 If we say that we have not sinned, we make him a liar, and his word is not in us.
May God add His blessing to the study of his word. “Good night” and God bless!
