Much has been said about the power of the Latter-day Saints. Is it the people called Latter-day Saints that have this power, or is it the Priesthood? It is the Priesthood; and if they live according to that Priesthood, they can commence their work here and gain many victories, and be prepared to receive glory, immortality, and eternal life, that when they go into the spirit-world, their work will far surpass that of any other man or being that has not been blessed with the keys of the Priesthood here. 7:288-9.
There is not a despot upon the earth whose power has not originally sprung from the Priesthood, and there is not a law in the Priesthood but what is founded on the revelations of Jesus Christ. These are the laws upon which all governments were originally based. Truth will endure forever, and every person that cannot abide truth will fail in obtaining eternal life. Truth is what we have. Let us live to it, and we shall abide for ever and no power can prevent it. 7:149.
When the faithful Elders, holding this Priesthood, go into the spirit world they carry with them the same power and Priesthood that they had while in the mortal tabernacle. 3:371.
When the holy Priesthood is upon the earth, and the fulness of the Kingdom of God has come to the people, it requires a strict obedience to every point of law and doctrine and to every ordinance which the Lord reveals. 10:286.
Were your faith concentrated upon the proper object, your confidence unshaken, your lives pure and holy, every one fulfilling the duties of his or her calling according to the Priesthood and capacity bestowed upon you, you would be filled with the Holy Ghost, and it would be as impossible for any man to deceive and lead you to destruction as for a feather to remain unconsumed in the midst of intense heat. 7:277.
An individual who holds a share in the Priesthood, and continues faithful to his calling, who delights himself continually in doing the things God requires at his hands, and continues through life in the performance of every duty will secure to himself not only the privilege of receiving, but the knowledge how to receive the things of God, that he may know the mind of God continually; and he will be enabled to discern between right and wrong, between the things of God and the things that are not of God. And the Priesthood—the Spirit that is within him, will continue to increase until it becomes like a fountain of living water; until it is like the tree of life; until it is one continued source of intelligence and instruction to that individual. 3:192.
It is the privilege of every person who is faithful to the Priesthood, who can overcome the enemy, thwart the design of death, or him that hath the power of it, to live upon the earth until their appointed time; and they may know, see, and understand, by revelation, the things of God just as naturally as we understand natural things that are around us. 3:192-193.
All the acts we perform should be governed by the guidance of the Priesthood. 7:64.
There is no act of a Latter-day Saint—no duty required—no time given, exclusive and independent of the Priesthood. Everything is subject to it, whether preaching, business, or any other act pertaining to the proper conduct of this life. 7:66.
Until a selfish, individual interest is banished from our minds, and we become interested in the general welfare, we shall never be able to magnify our holy Priesthood as we should. 11:115.
