“Once you have accepted it [shift to vision] as the only perception you want, it is translated into knowledge by the part that God Himself plays in the Atonement, for it is the only step in it He understands. Therefore, in this there will be no delay when you are ready for it. God is ready now, but you are not. (T-15.IV.1)”
This quotation explains the movement made by God to raise us up to Awakening. We are told here that God does not understand some things about our illusion. The Holy Spirit, God’s Voice, however, does. And the Holy Spirit guides us to the only perception that works: the perception that leads to true vision.
Vision is not of the physical eyes. It sees reality instead, and we do not have to look with physical eyes to identify reality. Once we have vision, we also have knowledge, which is a step beyond perception (according to ACIM) to what is really true. Knowledge cannot be taught, but comes from God when we are ready. And He Himself decides when that is. He calls us to Awaken.
When we Awaken, our channels of communication with God are once again open. He knows that we no longer sleep and need to be Awakened. His metaphorical loneliness is healed, and, not incidentally, our loneliness as well. We had taught ourselves the most unnatural habit of not communicating with our Creator. Now we do communicate, our minds returned to His.
Jesus says that we are not yet ready. We will know the readiness as soon as it appears possible in our experience. God will not delay; He wants us to come to Him as Awakened beings with a knowledge of Love.
