By poets, and by senators unpraised,
Which monarchs cannot grant, nor all the powers
Of earth and hell confederate, take away;
A liberty which persecution, fraud,
Oppression, prisons, have no power to bind;
Which whoso tastes can be enslaved no more.
’Tis liberty of heart, derived from Heaven,
Bought with His blood, who gave it to mankind,
And sealed with the same token.
Cowper.
