We are armed with the word of God, not only that we may smite our own spiritual foes, but that we may win men for Christ. As the Israelites had to conquer Canaan, so have we to conquer the world for Jesus. Go ye up against the ramparts of error, go ye up against the hosts of evil, with no weapon in your hand but the story of the cross, the revelation of the Most High, the declaration of the gospel of Jesus, for by this sign we conquer; it is impossible that we should fail with the gospel in our hands.
– Charles Spurgeon –
