Isaiah 7: a frequently misinterrpreted verse in the Bible

This is a funny verse.  In Isaiah 7:14 Isaiah says "behold a maiden will get pregnant and she will bear a son and she will name him Immanuel.".
Christians love this verse because they like to say that Immanuel is jesus.   Christians will often cite this verse in their missionary work.

To me, this verse strikes me as an indication of a coming of a new soul.  But I suggest that rather than this soul being that of a messiah or a major figure in the future, it actually is a calling upon you to rename your own soul rather than expect a new soul from the external to take over your whole life.
No, this is a different verse entirely.
The fact is that the entire bible calls upon the soul to reform and change.  No one who reads the True Jewish Scriptures from Genesis to Chronicles 2 on a regular basis will stay the same. 
The words transform your whole being.

Immanuel is the nature of the soul when it becomes purified.  So the reading you do in your Tanakh will pay off.  This is an indication that with much work, the reaches of Israel in your own soul can be acheived and solidified into a remnant of Israel so that you can stand where Israel was lost.

The discussion that he will eat the cream and honey as soon as he known to abhor evil and choose good indicates that your soul will profit from the relationship that it has with your own being.
The verse that "for before the child will known to abhor evil and choose good, the land of the two kings whom you fear will be abandoned" refers to the fact that you will indeed ascertain your own goodness and find a place of trust in your own heart for your own inclinations.  The land of the two kings is the fact that you are ruled by a yetzer hara and a yetzer tov (evil and good inclination).  The fact that it will be abandoned is to distance yourself from this conflict of double rule as you purify your soul and being and thus you will no longer live in a land ruled by 2 kings.  Thus you will let your yetzer tov rule indefinately and be on a true path of being "on the derech" as the Jewish axiom speaks of a Jew who is on the right path.
