Brigham Young: Perfection of Believers Will Only Become a Reality In the Hereafter

A man who has had his mind opened to the operation of the Priesthood of the Son of God—who understands anything of the government of heaven, must understand that finite beings are not capable of receiving and abiding the celestial law in its fulness. When can you abide a celestial law? When you become a celestial being, and never until then. When you hear men and women talk about living a celestial law, you may know that they are ignorant of the fact that no finite being is living in its fulness, or can. As it is written, we have line upon line, precept upon precept, here a little and there a little, and it is something that accords with the capacity of finite beings, and you improve upon this, and the Lord will open your minds to receive more, and let you see the order of the eternal Priesthood; but if you do not live your religion, you cannot receive more. (JOD 7:143 | May, 22, 1859)
