In the grim struggle with the invisible enemies of our salvation, the supreme weapon is the prayer of Jesus. `All the nations’ – the vociferous and wily demons are called nations – `surround me,’ says David, `and in the name of the Lord I repulsed them. They encircled and surrounded me like bees, and they burnt like fire among thorns; and in the name of the Lord I repulsed them’ (Ps. 117:10-12). With the name of Jesus flog the foes, because there is no stronger weapon in heaven or earth.
