Lord, how can man preach thy eternall word?
He is a brittle crazy glass:
Yet in the temple thou dost him afford
This glorious and transcendent place,
To be a window, through thy grace.
But when thou dost anneal in glasse thy storie,
Making thy life to shine within
The holy preachers; then the light and glorie
More reverend grows, & more doth sin:
Which else shows watrish, bleak & thin.
Doctrine and life, colours and light, in one
When they combine and mingle, bring
A strong regard and aw: but speech alone
Doth vanish like a flaring thing,
And in the eare, not conscience ring.
George Herbert (1593-1633), The Windows.
