I would not be the sport and prey of wild, vain, foolish, and worse imaginations: but this evil is present with me. My heart is like a highway, like a city without walls or gates: nothing so false, so frivolous, so absurd, so impossible, or so horrid, but it can obtain access, and that any time, in any place. Neither the study, the pulpit, nor even the Lord’s table exempt me from their intrusion.
