Context: God of grace and God of glory,
On Thy people pour Thy power.
Crown Thine ancient church’s story,
Bring her bud to glorious flower.
Grant us wisdom, grant us courage,
For the facing of this hour,
For the facing of this hour.

Context: There is no living thing that is not afraid when it faces danger. The true courage is in facing danger when you are afraid, and that kind of courage you have in plenty.

Speech to Conservative Rally at Cheltenham (3 July 1982) http://www.margaretthatcher.org/document/104989, regarding the Falkland Islands War.
First term as Prime Minister
Context: When we started out, there were the waverers and the fainthearts. The people who thought that Britain could no longer seize the initiative for herself. The people who thought we could no longer do the great things which we once did. Those who believed that our decline was irreversible—that we could never again be what we were. There were those who would not admit it—even perhaps some here today—people who would have strenuously denied the suggestion but—in their heart of hearts—they too had their secret fears that it was true: that Britain was no longer the nation that had built an Empire and ruled a quarter of the world. Well they were wrong. The lesson of the Falklands is that Britain has not changed and that this nation still has those sterling qualities which shine through our history. This generation can match their fathers and grandfathers in ability, in courage, and in resolution. We have not changed. When the demands of war and the dangers to our own people call us to arms—then we British are as we have always been: competent, courageous and resolute.
