One of our authors, Sarah, posted recently about mourning (For those who are mourning). Today in my devotional reading, I found a bit more about this topic in Of the Imitation of Christ by Thomas a Kempis.
“A good man finds always sufficient cause for mourning and weeping. For whether he considers himself or thinks of his neighbor, he knows that none lives here without tribulation. And the more thoroughly a man considers himself, so much the more he sorrows.
Matter of just sorrow and inward contrition are our faults and sins, in which we lie so enwrapped that rarely have we power to contemplate the things of Heaven.”
