Why do you continue to duck around my questions? What is more, I have already addressed and rebutted your argument above and you have already avoided my rebuttal.
Your questions have been repeatedly answered, but since you don't like the answers, you give no biblical rebuttal and instead misquote, or take what is said out of context to make it appear I don't believe in spirits of God called angels or spirits of Satan called demons.
The phase "the beginning" typically refers to the beginning of creation and earth. Just like the regeneration when Jesus comes refers to "the end" of creation and earth as we know it. Every solid theologian I know believe that Satan rebelled and fell before the beginning of creation and earth. He was a leader of the angelic host in. heaven.
This is the problem with erroneous doctrines that continue to be perpetuated throughout churches. Instead of seeking understanding regarding Satan and his demonic messengers from the Word of God, you and many like you rely on what other theologians believe, because they too rely on the doctrines of other theologians/commentaries instead of digging deep into what God says regarding spirit messengers throughout Scripture.
You have maligned and misquoted, taking out of context many replies here rather than showing from the Word of God how what I've actually stated is not biblical. You do this, I believe, because you cannot accept your erroneous understanding of Satan who was from the very beginning of creation called a murderer and liar. Unless you can prove the theologians, you're rely on for understanding of Satan can be proven from the Word of God, that Satan rebelled and fell before creation and was once the leader of the angelic host in heaven, your doctrine remains speculation without biblical merit.
The question regarding the existence of Satan I believe stems from these verses:
Genesis 1:2 (KJV) And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
Isaiah 45:7 (KJV) I form the light, and create darkness: I make peace, and create evil: I the LORD do all these things.
Darkness throughout the Bible is used metaphorically as misery, destruction, death, ignorance, sorrow, wickedness. Why/when did God create the darkness? Because it seems to already exist when God formed the light. Why does God tell us darkness and evil are created by Him?
If the darkness existed at the time God formed the light, is the darkness metaphorically spirit of darkness called Satan? I've come to believe it is, and the reason God did not conquer or destroy it but only invaded the darkness by light is because man was not created with knowledge of good or evil. These cannot be fully known by mankind without experiencing them. Therefore, the evil spirit enticed the woman in the form of a serpent so that man would not only come to know how sin and death through sin if left undefeated would utterly destroy all that God created "very good." Darkness and evil have been and are used by God to drive man to the Lamb slain from before the foundation of the world. For man to be fully free they had to know both good as well as evil, otherwise they would be without understanding of eternal life from God as well as condemnation and eternal death.
