enjoy the vision bright...

I am struggling with a sermon to be delivered tomorrow. I have a vague idea of where I want it to end up but cant seem to come up with words that will get it there.
A part of it is expressed in this hymn (found in the 1865 edition of Hymns of the Spirt) which will serve as the prayer...

"The light pours down from heaven
And enters where it may
The eyes of all earth’s children
Are cheered with one bright day.

So let the minds true sunshine
Be spread o’er earth as free,
And fill our waiting spirits,
As the waters fill the sea

The soul can shed a glory
On every work well done
As even things most lowly
Are radiant in the sun

Then let each human spirit
Enjoy the vision bright
The truth which comes from heaven
Shall spread like heaven's own light

Till earth becomes God's temple
And every human heart
Shall join in one great service
Each happy in our part."

Blessings
