10剑是军装中唯一用作攻击的，也就是说，剑是神的军装中唯一用来攻击仇敌的。你也许不明白，这与我们主观经历话的杀死能力有什么关系。我们要明白这事，就必须看见，在属灵的争战里，我们不仅需要对付客观的仇敌，更需要对付主观的对头。撒但不只是我们外面的仇敌，也是我们里面的对头。……仇敌从外面来的攻击，不如对头从里面来的攻击严重。要对付这个里面的对头，我们需要经历话的杀死能力。不错，仇敌是在我们外面，但他的元素是在我们这人的所是里面。……因着仇敌把他自己注射到我们的所是里，我们所需要的，乃是话的杀死能力应用到我们身上，来对付仇敌在我们里面的元素。……在我们的经历中，最终我们会明白，最棘手的仇敌乃是己。己是我们最厉害的仇敌。我们许多次受试诱，都不是由于客观的仇敌，乃是由于己，就是我们自己内里的所是（以弗所书生命读经，九八七至九八八页）。
10The sword is the only aspect of the armor that is for offensive warfare; that is, it is the only item of God’s armor used for attacking the enemy. Perhaps you are wondering what this has to do with our subjective experience of the killing power of the word. If we would understand this, we must see that in spiritual warfare we must deal not only with the objective enemy but even the more with the subjective adversary. Satan is not only the enemy outside us; he is also the adversary inside us… The attacks of the enemy from without are not as serious as those of the adversary from within. To deal with this inward adversary we need to experience the killing power of the word. Yes, the enemy is outside us, but his elements are within our very being…Since the enemy has injected himself into our being, what we need is for the killing power of the word to be applied to us to deal with the elements of the enemy within us. In our experience we eventually come to realize that the most difficult foe is the self. The self is our worst enemy. Many times we are tempted not by an objective enemy but by the self, our own inner being. (Life-study of Ephesians, pp. 796-797)
