Perseverance.

No wrath of men, or rage of seas,
Can shake a just man's purposes;
No threats of tyrants, or the grim
Visage of them can alter him;
But what he doth at first intend,
That he holds firmly to the end.

God pardons those who do through frailty sin,
But never those that persevere therein.

Although we cannot turn the fervent fit
Of sin, we must strive 'gainst the stream of it;
And howsoe'er we have the conquest miss'd,
'Tis for our glory that we did resist.

Each must in virtue strive for to excel;
That man lives twice that lives the first life well.

In the hope of ease to come,
Let's endure one martyrdom.

If well thou hast begun, go on fore-right;
It is the end that crowns us, not the fight.
