The following treatise was not originally written for publication; but as it faithfully represents the process by which the minds of some, brought up in reverence and affection for the Christian faith, were relieved from the vague state of doubt that resulted on their cherished beliefs being overthrown or shaken by the course of modern thought, it has been suggested that it may, perhaps, be useful to others in the same position. Although their hold on the reason and intellect may have been lost or weakened, still the supernatural authority, the hopes, and the terrors of the gospel continue to cling to the heart and conscience, until they are effectually dislodged by considerations of mightier mastery over the heart and conscience. 'The strong man armed keepeth his palace' until the stronger one appears. Then the whole faculties, mental and moral, are set free, and brought into accord in the cause of Truth.
