Note that what I have presented has been based solely on God's own word the Bible (2 Timothy 3:16-17), and not on any teaching of men (2 Peter 1:20-21), much less of the devil (Matthew 16:23; 1 Timothy 4:1; 2 Timothy 4:2-4).

Regarding 1 Corinthians 10:20-21, note that it, like Revelation 2:14b,20b, refers only to those who eat meat sacrificed to idols with the intent, or the idea, that in doing so they're actually "fellowshipping" with the idols, as opposed to having the true knowledge (1 Corinthians 8:10a) to eat the meat just as meat, without ascribing any evil spiritual significance to it whatsoever (1 Corinthians 8:4-8; 1 Corinthians 10:25-31). For under the New Covenant, all foods are in themselves okay for all Christians, whether Jews or Gentiles, to eat (1 Timothy 4:4-5).
Regarding Revelation 16:19, note that there the "great city" which will be literally, topographically divided into 3 parts by a literal, future earthquake (Revelation 16:18) is the literal, earthly "great city" of Jerusalem, where Jesus Christ was crucified (Revelation 11:8, Luke 13:33). In Revelation 16:19, "great Babylon" is something bigger than just Jerusalem.
Also, in Revelation 16:19, "great Babylon" isn't the future, single, literal city of Babylon (in Iraq). For that won't be destroyed until Jesus Christ's Second Coming (Isaiah 13), which won't occur until after the 7th vial of the future Tribulation is completed, and the symbolic (and worldwide) "Mystery Babylon" (Revelation chapters 17-18) has already been destroyed by the cities of the nations being destroyed (Revelation 16:17,19, Revelation 19:2 to 20:6).
Be very, very careful about cursing others (Psalms 109:17-20, Psalms 79:12), especially Christians (Revelation 12:10, Proverbs 26:2). For you could simply be mistaken in your views, like Hananiah was (compare Jeremiah 28:15-17).

Regarding 1 John 2:19, note that it doesn't require (as is sometimes claimed) that apostate Christians were never real Christians, but can mean apostate Christians were never of the overcomers to the end (Revelation 3:5, Revelation 2:26). Real Christians who have their names written in the Book of Life can have their names blotted out if they fail to overcome to the end (Revelation 3:5, Revelation 2:26). People can really believe in Jesus Christ and His Gospel only for awhile, before at some point wrongly employing their free will to depart from the faith, to no longer believe, to commit apostasy (Luke 8:13; 1 Timothy 4:1; 2 Thessalonians 2:3), to the ultimate loss of their salvation (Hebrews 6:4-8, John 15:6; 2 Timothy 2:12b).
1 John 2:18-19 can refer to Christians who eventually became Gnostic-type Christians (cf. 2 John 1:7; 1 John 4:3), and so left the Church because of its continued, and correct, insistence that Christ is in the flesh (Luke 24:39).
Gnosticism is an ancient religious movement which says everything material is inherently evil, while only that which is pure spirit can be good. Gnosticism teaches all humans used to be pure spirit and dwelling in bliss from all eternity in a purely-spiritual heaven, called the "Pleroma", until by some mishap humanity fell into the material universe and became trapped in fleshly bodies. Gnosticism reviles YHWH, the God of Biblical Christians, and the Creator of the material universe and of all fleshly bodies, as an evil, subordinate deity, a "Demiurge", who is keeping humans imprisoned and suffering in fleshly bodies and in the material universe.
Gnosticism became one of the main enemies of the early Church, and it will become the greatest enemy of the Church during the future Tribulation of Revelation chapters 6 to 18 and Matthew 24. For the Antichrist will be a Gnostic. He will teach the Gnostic/antichrist lie that Christ isn't in the flesh (1 John 4:3). And the Antichrist, like the Gnostics, will utterly revile YHWH (Revelation 13:6, Daniel 11:36). The Antichrist (the individual-man aspect of Revelation's "beast") will instead bring the world into the conscious and open worship of Lucifer (Satan, the dragon) and himself (Revelation 13:4,8, Revelation 12:9).
Gnosticism has some core teachings in common with Buddhism and Hinduism:
1. The material realm is unreal and evil. (Both Buddhism and Gnosticism got this mistaken idea, originally called "Maya", from Hinduism.)
2. People must strive to escape the material realm completely, and enter a state which is wholly non-physical (Parinirvana in Buddhism, the Pleroma in Gnosticism). Buddhism and Gnosticism got this mistaken idea, originally called "Brahman", from Hinduism.
3. The way for people to get free from their imprisonment within the material realm is through their minds attaining a certain level of enlightenment (Nirvana in Buddhism, Gnosis in Gnosticism). Buddhism and Gnosticism got this mistaken idea, originally called "Moksha", from Hinduism.
4. The way for their minds to attain this certain level of enlightenment is through following the way of the Serpent (one legend of Buddhism says the Buddha was given the true Buddhism by the King of the Serpents; and in Gnosticism, Gnosis comes from the Christ/the Serpent). Both Buddhism and Gnosticism got this mistaken idea of the enlightening serpent, originally called "Kundalini", from Hinduism. (Regarding the serpent in Genesis 3, Gnostics see him as the good guy, while they see YHWH as the bad guy.)
The Bible contradicts each of the 4 points above:
1. The material realm is real, and was created by YHWH God as something very good (Genesis 1:31). God Himself is in the flesh (John 1:1,14, Luke 24:39) and remains wholly without sin (Hebrews 4:15). So there's nothing evil about matter in itself.
2. People must strive to attain to a resurrection (Philippians 3:11) in an immortal human body of flesh and bones like the immortal human body of flesh and bones which Jesus Christ obtained at His resurrection on the 3rd day after His death (Luke 24:39,46; 1 Corinthians 15:3-4,21-23,51-53, Philippians 3:21, Romans 8:23-25), and in which He will remain forever as Christians' fully-human mediator/high priest (1 Timothy 2:5, Hebrews 2:16-17, Hebrews 7:24-26). His tomb is empty (Matthew 28:6), and at His Second Coming, He will show the scars of the Crucifixion on His body (Zechariah 13:6, Zechariah 12:10-14).
3. Resurrected people who have been truly enlightened/illuminated (Ephesians 1:18, Hebrews 10:32) by Jesus Christ (John 14:6-7, John 8:32, John 3:36) will remain in the material realm (Revelation 20:4-6, Revelation 5:10, Revelation 2:26-29), ultimately living on a New Earth with God (Revelation 21:1-4).

No surprise. Satan knows the book of the Lord, the Word of God, as he shows by you yourself, as one of his messengers, among many many others. I am not fighting against the flesh and blood, I know your spirit, a deceiver spirit speaks through you, and tries to deceive who attend this Christian forum. You, Satan, from the beginning you uses the Word of God to deceive, as you did with the woman saying in reverse what God had said. God had saidGen.2:16) Of every tree of the garden thou mayest freely eat. God had said also that the tree of Life was in midst of the Garden. But you, Satan, with your cunning, you did take the Word of God and said to the woman: (Gen.3:1) Yea, hath God said, Ye shall NOT eat of every tree of the Garden? And you, Satan, you confounded the woman through the Word of God. And the woman answered: We may eat of the fruit of the trees of the Garden (right): But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die. (Not true, God did not said that, the woman did lie). The tree in the midst was the tree of Life. (Today is JESUS, and the woman is the true Church of the Lord JESUS.)
From what has been stated above, the believers can perceive how astute is Satan speaking by his messengers. The Apostle Paul warned: It is no great thing if the ministers of the Devil also be transformed as the ministers of righteousness; whose end shall be according to their works. (2Cor.11:15)
Hear who has ears to hear. The believers must bi vigilant mainly when Satan speak the truth for you, as he did with our Lord JESUS. Satan said the truth to JESUS: (Matt.4:v.6) And (Satan) saith unto him (JESUS), If thou be the Son of God, cast thyself down: for it is written, He shall give his angels charge concerning thee: and in their hands they shall bear thee up, lest at any time thou dash thy foot against a stone. (TRUE)
Again I alert all the believers: : Take care when Satan uses Scriptures to lay a trap for you believer, as he tried to do with our Lord JESUS. Even now, in this Christian forum, Satan is using the Bible2 to lay a trap for you. Beloved, believe not every spirit, but try the spirits whether they are of God.
Hence from here Satan does not pass, he will be cast into the abyss now, in this present millennium.
