A quote from the book "Let God" by Francois Fenelon
"My heart is now suffering; but it is the life of self that causes us pain; that which is dead does not suffer. If we were dead, and our life were hid with Christ in God, (Col. iii. 3,) we should no longer perceive those pains in spirit that now afflict us. We should not only bear bodily sufferings with equanimity, but spiritual affliction also, that is to say, trouble sent upon the soul without its own immediate act. But the disturbances of a restless activity, in which the soul adds to the cross imposed by the hand of God, the burden of an agitated resistance, and an unwillingness to suffer, are only experienced in consequence of the remaining life of self."
