The whole Bible is written exactly according to what God said and declared by Himself or through His chosen priests, prophets, kings, apostles, and disciples. What the Father God, Jesus Christ and the Holy Spirit said was written by His chosen people as the Word of God and we can declare His words as "It is written " The word of God transcends time, space and human understanding and what is written in the Bible must not be altered, modified, changed or rescinded by any other authority on the earth. God's word is the final answer. Satan, all of the hosts of evil power and wicked men cannot alter what God has established in the Bible for all of His creations in the heavens and the earth.There have been too many books written about "spiritual warfare against the devil and the power of darkness." Those books have mostly focused (even magnified) the power of Satan more than the power of God. The Almighty God (Yahweh) created Lucifer as one of the archangels in heaven for His glory. When Lucifer fell from the glory of God, it was El Shaddai (the Almighty God) who cast him out of the kingdom of heaven into the earth. Ultimately, God will cast Satan, demons, false prophets and unbelievers into the lake of fire forever as stated in Revelation 20:10-15. Even though It is Written Satan exercises his evil power over fallen mankind by enticing them with his deceptions, lies and manipulations, the Lord is in control over the history of mankind as the Alpha and the Omega, the Beginning and the End.
