John now continues 

in his discourse on the woman. Again he goes back to verse six and makes it clearer in verses 13 through 17. The devil will be trying to persecute, destroy and flood out the truth with his deceptive lies, half Bible truths, government regulations and popular pressure. The time of this great persecution would last 1260 days (years). Revelation is picking up the same time concepts that are used by Daniel. 1260 days; time, times and half a time; and 42 months are all the same time period. Both chapters, Revelation 12 and Daniel 7 are talking about the persecution of the church of God during this same time period.

John tells us in Revelation 12 how we know who the true church of God is. In verse 17 he tells us that the true church is the one that obeys, keeps, the Ten Commandments of God and obeys the Testimony, teachings, of Jesus. Those who refuse to keep the Ten Commandments and refuse to hold to the teachings of Christ are on the side of the dragon and those who war against the true church of God. 2 John: 9
