And I heard a loud voice saying in heaven, 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. (Revelation 12:10)
Satan was the accuser of the brethren in OT days (see Job 1:8-12; Zech. 3:1). This role he has continued since the cross, but in a restricted sense (see on John 12:31; cf. DA 761). Rabbinical writings frequently represent Satan as the great accuser (see Talmud Sanhedrin 89b, Soncino ed., p. 595; Midrash Rabbah, on Ex. 32:2, Soncino ed., p. 494).
His Christ.
Or, “His Anointed.” Christ means “anointed” (see on Matt. 1:1).
Power.
Gr. exousia, “authority.”
Kingdom.
Satan had contended that he was the rightful ruler of this world. His failure to lead Jesus into sin assured the kingdom for Christ.
Strength.
Gr. dunamis, “power,”“might,”“strength.” The reference here is doubtless to the display of power in the overthrow of the dragon.
Salvation.
Gr. sōtēria, “deliverance,”“preservation,”“salvation,” here, perhaps, “victory.” The Greek has the article, hence we should read “the victory.”
Now is come.
The focus of time is the cross (see on vs. 7, 9). Well might the inhabitants of heaven rejoice, for Satan’s destruction was now assured. It was certain in the plan of God before, but now heavenly intelligences joined in the song, for they had seen Satan’s malignity against Christ revealed at Calvary.
A loud voice.
There is great rejoicing in the courts of heaven over the casting down of Satan and his host.
