The look on the face of the first Amiller when he realized the Greek word χίλιοι chílioi denotes one thousand and a one-thousand year period, and when he discovered all the warnings regarding Satan and his activities in the world given by Jesus and His apostles; and when he noticed the fact that in Revelation 12 we are told that the devil has been cast out of heaven, has come down to the earth and the sea "having great wrath, knowing that he has but a little time." (Revelation 12:12); and when he noticed the fact that we are then told about Satan going to war against "the woman" who had given birth to the Messiah, and then against "the rest of her seed, who keep the commandments of God and have the testimony of Jesus Christ." (Revelation 12:13-17), which of course, refers to Satan's war against the churches of Christ:
In Revelation 2:12 Jesus tells the church at Pergamos, "I know your works, and where you live, even where Satan's seat is. And you hold fast My name and have not denied My faith, even in those days in which Antipas was My faithful martyr, who was slain among you, where Satan dwells."
In Revelation 2:9-10 Jesus tells the church in Smyrna, "I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan. Fear none of those things which thou shalt suffer: behold, the devil shall cast some of you into prison, that ye may be tried; and ye shall have tribulation ten days: be thou faithful unto death, and I will give thee a crown of life.".
In his letter to the Christians in Corinth, Paul states, "But if our gospel be hid, it is hid to them that are lost: In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them." (2 Corinthians 4:3-4).
In Ephesians 6:11-12 Paul tells the Christians in Ephesus to "put on the whole armour of God, for your being able to stand against the wiles of the devil", and then continues to say, "because we have not the wrestling with blood and flesh, but with the principalities, with the authorities, with the world-rulers of the darkness of this age, with the spiritual things of the evil in the heavenly places".
In Acts 26:17-18, we read of Jesus telling Paul that He was sending Paul to the Gentiles ""To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me."
In Acts 5:3 we read that Peter said to a man named Ananias, "why hath Satan filled thine heart to lie to the Holy Ghost, and to keep back part of the price of the land?"
In Romans 16:20, Paul tells the church in Rome that "And the God of peace shall bruise Satan under your feet shortly."
In 1 Corinthians 5:5 Paul tells the church in Corinth to deliver the person who had sinned grievously unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus."
In 1 Corinthians 7:5 Paul says to the married couples in the same church, "Do not deprive one another, unless it is with consent for a time, so that you may give yourselves to fasting and prayer. And come together again so that Satan does not tempt you for your incontinence."
In 2 Corinthians 2:11 Paul tells the same church to forgive the person who sinned "Lest Satan should get an advantage of us: for we are not ignorant of his devices."
In 2 Corinthians 11:13-15 Paul refers to teachers of false doctrines who sought to beguile Christians as "false apostles, deceitful workers, transforming themselves into the apostles of Christ", and then goes on to say, "Did not even Satan marvelously transform himself into an angel of light? Therefore it is no great thing if his ministers also transform themselves as ministers of righteousness, whose end shall be according to their works." (2 Cor 11:14-15).
So Paul was calling the teachers of false doctrine "ministers (servants) of Satan".
In 1 Thessalonians 2:18 Paul tells the Christians in Thessaloniki that he had and those who accompanied him on his journeys tried to come to them, "but Satan hindered us."
In 1 Timothy 5:15 Paul says that some Christians "have already turned aside after Satan."
In 1 Timothy 3:6-7 Paul says that anyone desiring the office of a Bishop should "not a novice, lest being puffed up he may fall into the condemnation of the Devil; and it behoveth him also to have a good testimony from those without, that he may not fall into reproach and a snare of the devil."
James tells Christians, "Therefore submit yourselves to God. Resist the devil, and he will flee from you." (James 4:7).
Peter tells Christians to "Be sensible and vigilant, because your adversary the Devil walks about like a roaring lion, seeking someone he may devour; whom firmly resist in the faith, knowing that the same afflictions in the world are being completed in your brotherhood." (1 Peter 5:8-9).
