[King Solomon]: …"As long as the festivity
of Paradise shall be, so long shall our
love radiate around us such a garment.
Its brightness takes its measure from our ardor,
our ardor from our vision, which is measured
by what grace each receives beyond his merit.
When, glorified and sanctified, the flesh
is once again our dress, our persons shall,
in being all complete, please all the more;
therefore, whatever light gratuitous
the Highest Good gives us will be enhanced –
the light that will allow us to see Him;
that light will cause our vision to increase,
the ardor vision kindles to increase,
the brightness born of ardor to increase.
Yet even as a coal engenders flame,
but with intenser glow outshines it, so
that in the flame the coal persists, it shows,
so will the brightness that envelops us
be then surpassed in visibility
by reborn flesh, which earth now covers up." (Par. XIV, 37-57)
Solomon's words inform us that the souls' light stems from their love for God. The depth of their love for God comes from the perfection of their vision. Interestingly, their lights serve as a sort of substitute for their earthly raiment – physical bodies. When Judgment Day comes, the blessed shall be reunited with their physical bodies and shine even brighter because they will be complete and merit more of God's grace.
