The sixth piece of God's armor is the sword of the Spirit, which is identified as the Word of God. Many have understood that the Sword of God is the only offensive weapon listed in God's armor. I would also like to note that the Sword is not identified with, but is closely associated with prayer in Ephesians. In other words, Paul encourages the Ephesians to use God's Word as a weapon, and, in the same breath, pray for the gospel to go out.
The Word is a weapon against Satan, because it proclaims truth. And Satan is the father of lies. And when we wield this Sword, especially in prayer, we disrupt, and destroy, Satan's lies, and his kingdom of evil.
Of course, the war we wage is different. In normal war, the result is the death, and defeat of your enemies. In the war God's family wages, the lies of the enemy are destroyed. Members of the enemy, 's army are defeated, but they turn around, and become part of God's family. The overall result is greater obedience to God's word, greater love for God, greater faith in Jesus, and greater love for people.
We are in a war, but we do not seek the destruction of our enemies. We seek their surrender, and allegiance, to the King of Kings. We use the armor to complete God's mission.
And a vital part of that mission is prayer, reminding God of his promises, so that his Spirit will bombard the hearts of those on earth, and they come to know the God of creation, and turn to him.
