I understand four manner of dreads. One is the dread of an affright that cometh to a man suddenly by frailty. This dread doeth good, for it helpeth to purge man, as doeth bodily sickness or such other pain as is not sin. For all such pains help man if they be patiently taken. The second is dread of pain, whereby man is stirred and wakened from sleep of sin. He is not able for the time to perceive the soft comfort of the Holy Ghost, till he have understanding of this dread of pain, of bodily death, of spiritual enemies; and this dread stirreth us to seek comfort and mercy of God, and thus this dread helpeth us, and enableth us to have contrition by the blissful touching of the Holy Ghost. The third is doubtful dread.
Julian of Norwich
