"And He said, It is finished."
One only, of God's messengers to man,
Finish'd the work of grace, which He began;
E'en Moses wearied upon Nebo's height,
Though loth to leave the fight
With the doom'd foe, and yield the sun-bright land
To Joshua's armèd hand.
And David wrought in turn a strenuous part,
Zeal for God's house consuming him in heart;
And yet he might not build, but only bring
Gifts for the Heavenly King;
And these another rear'd, his peaceful son,
Till the full work was done.
List, Christian warrior! thou, whose soul is fain
To rid thy Mother of her present chain;—
Christ will avenge His Bride; yea, even now
Begins the work, and thou
Shalt spend in it thy strength, but, ere He save,
Thy lot shall be the grave.
John Henry Newman
