Excerpts from “The Gospel of God’s Love”, pages 73 – 76, from Luke the Physician:
“I want to tell you of the mystery of the birth of the soul in the human being. All souls which enter into human bodies are, previous to such advent, real, living existences, made in the likeness of the Great Soul, though not having all the qualities and potentialities of that Soul. They also do not have the form of individualized personality which they will have after they become parts of the composition of the mortal and spiritual bodies of human beings.
“The soul, in its existence prior to becoming an indweller in the mortal body, has a consciousness of its existence, and of its relationship to God and other children of that great Soul… When the time comes for this soul to become an indweller in the mortal frame, the two parts of the soul separate, and each part enters into a different mortal. While this soul, before separation, has a consciousness of its duplex existence, when this duplex character leaves it, and thereafter until its reentry into the spirit world, this consciousness does not again return to these parts.
“Now, as to what this soul is, in its constituent parts or shape, prior to its separation for the purpose of becoming an inhabitant of the mortal body, we spirits are not informed. We are often present at the conception and gestation, and also at the birth of a child, we realize that a soul has become enveloped in the flesh, but we cannot see that soul as it enters into its home of mortal environment because to us it is invisible; but after its lodgment in the human body, we can perceive its existence, for then it assumes a form.
“I know that people have often asked about the preexistence of the soul that has been incarnated, and what qualities it had during its preexistence, and to these particulars I wish to say that we spirits have little information, though we do know that the soul has an existence prior to its becoming individualized. We are of higher development and can, with the perceptions of our souls, understand the existence of these souls as images of the Over-Soul. We further understand that when the soul becomes incarnated and assumes an identity, it never thereafter loses that individuality.” Amen
