John 8:44
“He was a murderer from the beginning, and has nothing to do with the truth, because there is no truth in him. When he lies, he speaks out of his own character, for he is a liar and the father of lies.”

Satan, also known as the devil, was created by God as an angel. God removed Satan from his position in heaven due to his prideful sin of wanting to be on the throne above God. In his arrogance, he led a rebellion of angels against God and they are now doomed for eternity.

Satan hates God, God’s people, and God’s purposes. In his furious anger, he will do anything in his power to obstruct them. The devil still seeks worldly worship and to elevate his position above God. Unfortunately, many people do serve him over God. 

“Satan seeks to inject his evil and blasphemous thoughts about God into the hearts of the saints”
