And the Scriptures say that when the Lord shall bring again Zion her watchmen shall see eye to eye. They shall see alike, they shall comprehend alike, they shall be under the same influence.
What else shall it do? It shall show you of things to come. You shall be enabled to look through the dark vista of the unborn future, to draw aside the veil of the invisible world, and comprehend the things of God; to know your destiny and the destiny of the human family, and the events that will transpire in coming ages and times.
That is what the Holy Ghost will do, and therein is the difference between that Spirit and the little portion of that spirit which is given to every man to profit withal.
John Taylor; Journal of Discourses, 23:376.
