As Ephesians 6 – the key spiritual warfare passage – makes explicit, Satan focuses his efforts on extinguishing or corrupting our faith in Christ. That is why all of the weapons he lists for the believers’ struggle have to do with the objective Word of the gospel rather than on our own cleverly devised, if superstitious, technology. Satan’s favorite holiday is not Halloween but Christmas and Easter – in fact, every Lord’s Day when Christ gathers his people to himself. He foments external persecution an internal corruption of God’s Word and the believer’s faith. The Antichrist himself will assume his throne not in a capital of secular power but in the sanctuary of God (II Thessalonians 2:4). From Genesis to the Gospels, Satan’s favorite haunt is not wild parties and seances, but God’s courtroom, where he can accuse believers night and day. That is why it is so significant that Christ cast Satan out of heaven by his victorious ascension. It means that in heaven where our salvation is determined – there is no prosecutor, but only a defense attorney for the people of God.
