And yet not weep?

I have posted this before, but it is one of the best, so here is Christina Rossetti's Good Friday.

Good Friday

Am I a stone and not a sheep,
   That I can stand, O Christ, beneath Thy cross,
   To number drop by drop Thy Blood’s slow loss,
And yet not weep?

Not so those women loved
   Who with exceeding grief lamented Thee;
   Not so fallen Peter weeping bitterly;
Not so the thief was moved;

Not so the Sun and Moon
   Which hid their faces in a starless sky,
A horror of great darkness at broad noon—
   I, only I.

Yet give not o’er,
   But seek Thy sheep, true Shepherd of the flock;
Greater than Moses, turn and look once more
   And smite a rock.

~Christina Rossetti
