A day of sorrow is longer than a month of joy.- Chinese Proverb
Sorrow makes men sincere. -Henry Ward Beecher
Sorrow is only one of the lower notes in the oratorio of our blessedness.- Adoniram Gordon
I walked a mile with Pleasure,
She chattered all the way;
But left me none the wiser,
For all she had to say.
I walked a mile with Sorrow,
And ne'er a word said she;
But, oh, the things I learned from her,
When Sorrow walked with me!
Robert Browning Hamilton (1880-1950) _Along the Road_
Come, ye disconsolate, where'er ye languish
Come to the mercy seat, fervently kneel;
Here bring your wounded hearts, here tell your anguish:
Earth has no sorrow that heav'n cannot heal
Joy of the desolate, light of the straying,
Hope of the penitent, fadeless and pure!
Here speaks the Comforter, tenderly saying,
'Earth has no sorrow that heav'n cannot cure.'
Here see the Bread of Life; see waters flowing
Forth from the throne of God, pure from above:
Come to the feast of love; come, ever knowing
Earth has no sorrow but heav'n can remove."
Thomas Moore 1779-1852, Thomas Hastings 1784-1872
Sorrows remembered sweeten present joys. -Robert Pollock
Our trusting the Lord does not mean that there are not times of tears. I think it is a mistake as Christians to act as though trusting the Lord and tears are not compatible.- FRANCIS SCHAEFFER
When sorrows come, they come not single spies, but in battalions! -William Shakespeare (1564-1616) _Hamlet_ [1600-1601], Act IV, Sc.5, Ln. 78
Help someone in distress and you lighten your own burden; the very joy of alleviating the sorrow of another is the lessening of one's own.-Fulton John Sheen (1895-1979)_On Being Human_ 
The more you join in with people in their joys and their sorrows, the more nearer and dearer they come to be to you.... But it is sorrow and trouble that brings you the nearest.- Mark Twain
Where there is sorrow, there is holy ground.- Oscar Wilde
