A man that looks on glass

The Elixir
by George Herbert

Teach me, my God and King,
In all things Thee to see,
And what I do in anything
To do it as for Thee.

Not rudely, as a beast,
To run into an action;
But still to make Thee prepossest,
And give it his perfection.

A man that looks on glass,
On it may stay his eye;
Or it he pleaseth, through it pass,
And then the heav'n espy.

All may of Thee partake:
Nothing can be so mean,
Which with his tincture—"for Thy sake"—
Will not grow bright and clean.

A servant with this clause
Makes drudgery divine:
Who sweeps a room as for Thy laws,
Makes that and th' action fine.

This is the famous stone
That turneth all to gold;
For that which God doth touch and own
Cannot for less be told.

I love that third stanza. The importance of choices: look on the glass or through it.
