I am as God created me.
…this one thought would be enough to save you and the world, if you believed that it is true. Its truth would mean that you have made no changes in yourself that have reality, nor changed the universe so that what God created was replaced by fear and evil, misery and death. If you remain as God created you fear has no meaning, evil is not real, and misery and death do not exist.
Today’s idea is therefore all you need to let complete correction heal your mind, and give you perfect vision that will heal all the mistakes that any mind has made at any time or place. It is enough to heal the past and make the future free. It is enough to let the present be accepted as it is. It is enough to let time be the means for all the world to learn escape from time, and every change that time appears to bring in passing by.
