The world believes that to possess a thing, it must be kept. Salvation teaches otherwise.

No one can give what he has not received. To give a thing requires first you have it in your own possession. Here the laws of Heaven and the world agree. But here they also separate. The world believes that to possess a thing, it must be kept. Salvation teaches otherwise. To give is how to recognize you have received. It is the proof that what you have is yours.

You understand that you are healed when you give healing. You accept forgiveness as accomplished in yourself when you forgive. You recognize your brother as yourself, and thus do you perceive that you are whole. There is no miracle you cannot give, for all are given you. Receive them now by opening the storehouse of your mind where they are laid, and giving them away.
