Does Daniel 12 imply the righteous will become stars?

In sensus plenior;

Abraham's children are likened to dust [1], sand of the sea [2] and stars [2].

These represent three classes of Abraham's children:

   Dust are those without the water/word. The Arab nations descended from Abraham.

   Sand of the sea shore- those that are in close proximity to the water/word. The Jews

   Stars - those who are the lights of the world [3] and turning souls to Christ [4]. The church including saved Arabs and Jews.

Since Jesus is the firmament of Gen 1, and the stars are in the firmament, the church is 'in Christ'.

The direct answer then is that the stars are figurative.

[1] Ge 13:16 And I will make thy seed as the dust of the earth: so that if a man can number the dust of the earth, [then] shall thy seed also be numbered.

[2] Ge 22:17 That in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which [is] upon the sea shore; and thy seed shall possess the gate of his enemies;

[3] Mt 5:14 Ye are the light of the world. A city that is set on an hill cannot be hid.

[4] Da 12:3 And they that be wise shall shine as the brightness of the firmament; and they that turn many to righteousness as the stars for ever and ever.
