Analysis of The Angel of Pain

Angel of Pain, I think thy face
Will be, in all the heavenly place,
The sweetest face that I shall see,
The swiftest face to smile on me.
All other angels faint and tire;
Joy wearies, and forsakes desire;
Hope falters, face to face with Fate,
And dies because it cannot wait;
And Love cuts short each loving day,
Because fond hearts cannot obey
That subtlest law which measures bliss
By what it is content to miss.
But thou, O loving, faithful Pain-
Hated, reproached, rejected, slain-
Dost only closer cling and bless
In sweeter, stronger steadfastness.
Dear, patient angel, to thine own
Thou comest, and art never known
Till late, in some lone twilight place
The light of thy transfigured face
Sudden shines out, and, speechless, they
Know they have walked with Christ all day.
