^12:10 Then I heard a loud voice in heaven say:

“Now have come the salvation and the power
and the kingdom of our God,
and the authority of his Messiah.
For the accuser of our brothers and sisters,
who accuses them before our God day and night,
has been hurled down.

Then I heard a LOUD VOICE in heaven say:

This may be a relative "sound level". If the last part of this verse goes on continually, then heaven must have been/now is a very noisy place. Consider how many people are continually being accused before God (and Jesus). Silence in heaven is a very rare thing (see Revelation 8:1); if the saints aren't praising, the devil and his followers are accusing.

But now that the devil and his cohorts are "THROWN DOWN" to the earth, John hears the LOUD VOICE. This voice stands out above the rest of the loud voices when the seventh trumpet is sounded (Revelation 11:15).

"Now

  Once again, time enters the picture. NOW the fullness of salvation is realized. Here salvation is more than the act which gives a person eternal life. It includes the purging of heaven from evil for eternity. This is part of the John 14:1-11 "I go to prepare a place for you" Jesus talked about.

• the POWER and

  This POWER is the gospel (Romans 1:16-17). Note also that as in the Lord's prayer (Matthew 6:5-15), POWER is tied to

• the KINGDOM of OUR GOD, and

  This is not the first appearing of the KINGDOM of our God. It has been in existence forever. However, it is going through the "redemptive process" even as discussed in Revelation 5:1, point 7.

• the AUTHORITY of HIS MESSIAH.

For

• the accuser of our brothers and sisters,

  In action, Jesus Christ has just had enough. As High Priest (Hebrews 9:11-14), he stands at the right hand of God intercepting the accusations against mankind being hurled toward God. By action, Jesus indicates that because of HIS BLOOD (next verse), God cannot hear the accusations of the devil. The devil and his followers might as well reside on the earth and talk to the residents there, verse 12.

  The use of the pronoun, OUR, indicates this is a believer's view. This is confirmed in the next verse.

• who accuses them before our God day and night,

  When a person repents of their sins, the accusations become more intense. While the devil doesn't want anyone to accept Christ as Savior and the one with AUTHORITY, the believers are the ones he really would like to deceive and get back. So at this point, the accusations become more mental than physical. This allows us to understand what Paul meant when he says that Christ "cleanses our conscience" in Hebrews 9:14. Science indicates that the brain is very active even while we are asleep physically. This mental accusation also stops when we receive Christ completely into our lives.

• has been hurled down.

  Now all who dwell on the earth will have to make a decision about the DEVIL's control of their lives!
