One thing that has really stood out to me as I have studies the Doctrine & Covenants this year is that EVERY SINGLE PART of the restoration was given to us in the later days for the purpose of God's work and glory, to bring us back to Him. The priesthood, as we learn in these verses is KEY to that work!
