Blessed rest for the burthened sinner. Or the only center of the soul : Wherein is discovered. 1. Who he is that invites and calls sinners to this rest. 2. The encouragements to come unto him for rest. 3. Many obstructions and impediments which keep back sinners. With their unreasonableness answered. 4. The rest that every one shall have that comes unto Christ. Delivered in some sermons at first, yet since some addition and enlargement has been made to them. By John Hopwood preacher of the Gospel.
