A teacher of God is anyone who chooses to be one. His qualifications consist solely in this; somehow, somewhere he has made a deliberate choice in which he did not see his interests as apart from someone else's. Once he has done that his road is established and his direction is sure. A light has entered the darkness. It may be a single light, but that is enough. He has entered an agreement with God, even if he does not yet believe in Him. He has become a bringer of salvation. He has become a teacher of God.
They come from all over the world. They come from all religions and from no religion. They are the ones who have answered. The Call is universal. It goes on all the time everywhere. It calls for teachers to speak for it and redeem the world. Many hear it but few will answer. But it is all a matter of time. Everyone will answer in the end, but the end can be a long, long way off. It is because of this that the plan of the teachers was established. Their function is to save time. Each one begins as a single light, but with the Call at its center it is a light that cannot be limited. And each one saves a thousand years of time as the world judges it. To the Call itself time has no meaning.
There is a course for every teacher of God. The form of the course varies greatly. So do the particular teaching aids involved. But the content of the course never changes. Its central theme is always, "God's Son is guiltless, and in his innocence is his salvation." It can be taught by actions or thoughts; in words or soundlessly; in any language or in no language; in any place or time or manner. It does not matter who the teacher was before he heard the Call. He has become a savior by his answering. He has seen someone else as himself. He has therefore found his own salvation and the salvation of the world. In his rebirth is the world reborn.
This is a manual for a special curriculum, intended for teachers of a special form of the universal course. There are many thousands of other forms, all with the same outcome. They merely save time. Yet it is time alone that winds on wearily, and the world is very tired now. It is old and worn and without hope. There was never a question of outcome, for what can change the Will of God? But time, with its illusions of change and death, wears out the world and all things in it. Yet time has an ending, and it is this that the teachers of God are appointed to bring about. For time is in their hands. Such was their choice, and it is given them.
