Water and blood are the two signs present at every birth, and here they mark the birth of a new self rather than a body. Jesus Christ is your own human imagination, the one power that creates, and it is never born into your life by wishing alone. Water is the desire and the clear inner picture; blood is the feeling, the warm conviction that the thing is already so. Imagination that comes by water only, a picture held without feeling, stays unborn.
A state assumed and felt to be so does not announce itself by argument; it produces evidence. That is the Spirit bearing witness, and the witness cannot lie, because what you have inwardly become always shows itself outwardly. The self you accept and feel to be yours is the self your world will confirm.
