Vigilance

"To teach the whole Sonship without exception demonstrates that you perceive its wholeness, and have learned that it is one. Now you must be vigilant to hold its oneness in your mind because, if you let doubt enter, you will lose awareness of its wholeness and will be unable to teach it. The wholeness of the Kingdom does not depend on your perception, but your awareness of its wholeness does. It is only your awareness that needs protection, since being cannot be assailed. Yet a real sense of being cannot be yours while you are doubtful of what you are. This is why vigilance is essential. Doubts about being must not enter your mind, or you cannot know what you are with certainty. Certainty is of God for you. Vigilance is not necessary for truth, but it is necessary against illusions.

Truth is without illusions and therefore within the Kingdom. Everything outside the Kingdom is illusion. When you threw truth away you saw yourself as if you were without it. By making another kingdom that you valued, you did not keep only the Kingdom of God in your mind, and thus placed part of your mind outside it. What you made has imprisoned your will, and given you a sick mind that must be healed. Your vigilance against this sickness is the way to heal it. Once your mind is healed it radiates health, and thereby teaches healing. This establishes you as a teacher who teaches like me. Vigilance was required of me as much as of you, and those who choose to teach the same thing must be in agreement about what they believe. "

-ACIM, Be vigilant only for God and His kingdom, ch. 6

Our vigilence of mind must always be upon the true nature of our 'being', as one with God and the glory of his kingdom which is ever-eternal. Truth is inviolate, indivisible, unconquerable, of the substance of divinity, immortal. Only our awareness is called unto vigilance to abide in the Truth that IS, the kingdom of Light. By identifying only with 'God' and his Being, we hold our own truth in the Light, the wholeness of Sonship and are in 'conscious union' with the Father, illumined by the Spirit. It is ours to discern and hear the Voice of the Holy Spirit, being watchful to abide in our Christhood - it is then in such holiness of being...that we are empowered to teach what we are, for then what we are is most Radiant(to us and all) as the true creation (Son) of God.
