Arise [from spiritual depression to a new life], shine [be radiant with the glory and brilliance of the LORD ]; for your light has come, And the glory and brilliance of the LORD has risen upon you.
For, in fact, darkness will cover the earth, And deep darkness will cover the peoples; But the LORD will rise upon you, And His glory and brilliance will be seen on you. (Isa 60:1)
And what happens when you open up and shine in the darkness? The light within you will lead those who were themselves in deep darkness to come - to you.
