They walked to our bedside, laid hands upon our heads and we were instantly delivered; and from that time forth we were no more troubled with evil spirits while in the city of London.
As soon as they administered unto us they withdrew from the room, the lights withdrew with them and darkness returned.
Many other sayings of the Patriarch Joseph Smith in my blessing have been fulfilled in my experience, but I have said sufficient on this subject. All the blessings that are sealed upon our heads will be fulfilled, and many more, if we are faithful and live for them.
In closing my testimony I wish to say that I do not think that the Lord ever sends an angel to the earth to visit the children of men, unless it is necessary to introduce a dispensation of the gospel, or deliver a message, or perform a work that cannot be done otherwise.
It required an angel of God to deliver the gospel to Joseph Smith because it was not then upon the earth, and that was in fulfillment of the word of the Lord through John the Revelator (Revelations xiv. 6). And so in regard to the administrations of angels in all ages of the world; it is to deliver a message and perform a work which cannot otherwise be accomplished.
