John heard a loud voice speaking in heaven (Revelation 12:10).
“…Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night. And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death. Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhibiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knows that he hath but a short time. And when the dragon saw that he was cast unto the earth, he persecuted the woman which brought forth the man child. And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent.” (Revelation 12:10-14)
The salvation, of which the loud voice spoke, was what Jesus offered men through his death, resurrection, and ascension into heaven. Jesus told his disciples just before ascending into heaven that they would soon be baptized with the Holy Spirit (Acts 1:5). When that event occurred, they would be endowed with power (viz. Acts 2:1-12), and, because of that power, they would become his witnesses “…in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth” (Acts 1:8; cf. Acts 2:13-41).
According to Jesus, men sought to enter the Kingdom of God during his public ministry, but they were prevented from doing so by the Jewish authorities (Matthew 23:13; Luke 11:52). Therefore, it seems the Kingdom of God was initiated on the day of Pentecost (Acts 2; cf. Acts 1:3, 14:22), when power was given to the Apostles (Acts 1:8), and strength was given to those who believed on their word to remain in their doctrine, ignoring the intimidation of the Jewish authorities (cf. Acts 2:42-47; 4:7, 17).
The initiation of the Kingdom of God on Pentecost and the resulting belief that held believers together was evidence that Jesus ruled in their hearts. In other words the Kingdom of God was not evidenced through ocular data, so that one could say it was either here or there (cf. Luke 17:20-21). Rather, it was evidenced in the lives of those who were changed by the Gospel. God rules in the hearts of men, and they desire to do his will. In contrast to this, the Jewish authorities ruled over men through the Law, and they enforced the Law through their own power.
The conflict between Jesus’ disciples and the Jewish authorities occurred as a result of the accuser of the brethren being cast out of heaven (cf. Revelation 12:9). The word accuser is kategoros (G2725) in the Greek, and it occurs only six other times in the New Covenant Scriptures, besides how it is used in Revelation 12:10. In each case it points to the Jewish authorities at Jerusalem. In John 8:10 the Jewish authorities brought a woman to Jesus, claiming she had been caught in the act of adultery, but, after Jesus had convicted them of their own sin in the matter, he asked the woman where her accusers were. The remaining five occurrences of the Greek word (G2725) have to do with Paul’s accusers, the Jewish authorities at Jerusalem, who sought his life in the courts of Felix and Festus, Roman governors of Judea (Acts 23:30; Acts 23:35; Acts 24:8; Acts 25:16; Acts 25:18)
According to the theme of Revelation 12, the Serpent sought to maintain his authority over the earth. The polar star in the tail of the constellation, Draco, the dragon, was changing to Polaris, the star in the constellation The Lesser Sheepfold, known to us, today, as the Little Dipper. Concerning Polaris, the left foot of the King in the constellation, Cepheus (who in the context of Revelation 12 is Christ), is positioned over Polaris, the new polar star, implying a war over rulership of the world was then taking place. The whole universe revolves around the polar star, implying the possessor of that star is the God or god of this world (cf. 2Corinthians 4:4). In this war in heaven, which was played out in the lives of Jesus and his disciples and their enemies of the first century AD, the Serpent was cast out (Revelation 12:10), and the kingdoms of this world had become the kingdoms of the Lord and his Christ (Revelation 11:15; cf. 12:7-8). Today, Jesus is the God of this world, not Satan (2Corinthians 4:4) as the precession of the Zodiac foretold would be the case.
