The battle between God's kingdom and Satan's
The battle between God's kingdom and Satan's tyranny rages all around us but the Bible insists that we are watching a battle being won, not lost. Our Christian faith celebrates the fact that Satan is a defeated foe, but we know from bitter experience that his death throes are lethally protracted until the return of Christ. 'He is filled with fury, because He knows that his time short' (Rev. 12:12). The biblical scholar Church Lowe puts it graphically:
Like a wounded and cornered animal, Satan thrashes around desperately with the aim of injuring as many of his enemy as possible, before his own destruction...So the defeat of Satan does not mean the end of trouble for the church. To the contrary, it signals an escalation and intensification of opposition and persecution. But the end is in sight, and those who endure to the end shall be victorious even if, in the mean time, they become victims.
