The Atonement of the Lord Jesus Christ is the heart and core and center of revealed religion.

Elder Bruce R. McConkie Christ and the Creation

What was it that suddenly changed these disciples to confident, fearless, heroic preachers of the gospel of Jesus Christ? It was the revelation that Christ had risen from the grave. His promises had been kept, his Messianic mission fulfilled. In the words of one universal writer, “The final and absolute seal of genuineness had been put on all his claims, and the indelible stamp of a divine authority upon all his teachings. The gloom of death had been banished by the glorious light of the presence of their risen, glorified Lord and Savior.”

On the evidence of these unprejudiced, unexpectant, incredulous witnesses, faith in the resurrection has its impregnable foundation.

President Henry B. Eyring speaking about President McKay and Moroni:
You have felt a tug, maybe many tugs, to be someone better. And what sets those yearnings apart from all your daydreams is that they were not about being richer or smarter or more attractive but about being better.

I am sure you have had such moments, not just from my experience but because of what President David O. McKay once said. Listen very carefully:
“Man is a spiritual being, a soul, and at some period of his life everyone is possessed with an irresistible desire to know his relationship to the Infinite. . . . There is something within him which urges him to rise above himself, to control his environment, to master the body and all things physical and live in a higher and more beautiful world” (True to the Faith: From the Sermons and Discourses of David O. McKay, comp. Llewelyn R. McKay, Salt Lake City, Bookcraft, 1966, 244)

That pull upward is far beyond what you would call a desire for self-improvement. When I felt it, I knew I was being urged to live so far above myself that I could never do it on my own. President McKay had it right. You feel an urging to rise above your natural self. What you have felt is an urging from your Heavenly Father to accept this invitation:

“Yea, come unto Christ, and be perfected in him, and deny yourselves of all ungodliness; and if ye shall deny yourselves of all ungodliness, and love God with all your might, mind and strength, then is his grace sufficient for you, that by his grace ye may be perfect in Christ; and if by the grace of God ye are perfect in Christ, ye can in nowise deny the power of God.
“And again, if ye by the grace of God are perfect in Christ, and deny not his power, then are ye sanctified in Christ by the grace of God, through the shedding of the blood of Christ, which is in the covenant of the Father unto the remission of your sins, that ye become holy, without spot.” (Moroni 10:32–33)

That urge to rise above yourself is a recognition of your need for the Atonement to work in your life, and your need to be sure that it is working. After all you can do, after all your effort, you need confidence that the Atonement is working for you and on you.

President David O. McKay said, “Man is a spiritual being, and sometime or another every man is possessed with a longing, an irresistible desire, to know his relationship to the Infinite. He realizes that he is not just a physical object to be tossed for just a short time from bank to bank, only to be submerged finally in the ever-flowing stream of life. There is something within him that urges him to rise above himself, to control his environment, to master the body and all things physical, and to live in a higher and more beautiful world.” (Conference Report, April, 1968, Priesthood Session)

Jesus said:

And my Father sent me that I might be lifted up upon the cross; and after that I had been lifted up upon the cross, that I might draw all men unto me, that as I have been lifted up by men even so should men be lifted up by the Father, to stand before me, to be judged of their works, whether they be good or whether they be evil—

And for this cause have I been lifted up; therefore, according to the power of the Father I will draw all men unto me, that they may be judged according to their works. (3 Nephi 27:14-15)

The upward pull comes from our Savior, Jesus Christ, who is drawing us towards Him, reminding us that our true home is another, higher place where only He can take us.
