The scriptures make it clear that there will be a great day of judgment when the Lord will stand to judge the nations (see 3 Nephi 27:16) and when every knee will bow and every tongue confess that He is the Christ (see Romans 14:11; Mosiah 27:31; D&C 76:110). The individual nature and extent of that judgment are described by Alma in the Book of Mormon:
"For our words will condemn us, yea, all our works will condemn us; we shall not be found spotless; and our thoughts will also condemn us; and in this awful state we shall not dare to look up to our God; and we would fain be glad if we could command the rocks and the mountains to fall upon us to hide us from his presence.
"But this cannot be; we must come forth and stand before him in his glory, and in his power, and in his might, majesty, and dominion, and acknowledge to our everlasting shame that all his judgments are just; that he is just in all his works, and that he is merciful unto the children of men, and that he has all power to save every man that believeth on his name and bringeth forth fruit meet for repentance" (Alma 12:14–15).
When the Savior defined His gospel, this judgment was central to it. He said:
"Behold I have given unto you my gospel, and this is the gospel which I have given unto you—that I came into the world to do the will of my Father, because my Father sent me.
"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 27:13–15).
Being "lifted up upon the cross" is, of course, a symbolic way of referring to the Atonement of Jesus Christ by which He satisfied the demands that justice may have upon each of us. In other words, by His suffering and death in Gethsemane and on Golgotha, He paid all that justice could demand of us for our sins. He therefore stands in the place of justice and is the personification of justice. Just as God is love, God is also justice. Our debts and obligations now run to Jesus Christ. He, therefore, has the right to judge us.
That judgment, He states, is based on our works. The especially "good news" of His gospel is that He offers the gift of forgiveness conditioned on our repentance. Therefore, if our works include the works of repentance, He forgives our sins and errors. If we reject the gift of pardon, refusing to repent, then the penalties of justice that He now represents are imposed. He said, "For behold, I, God, have suffered these things for all, that they might not suffer if they would repent; but if they would not repent they must suffer even as I" (D&C 19:16–17).
Always remembering Him, therefore, means that we always remember that nothing is hidden from Him. There is no part of our lives, whether act, word, or even thought, that can be kept from the knowledge of the Father and the Son. No cheating on a test, no instance of shoplifting, no lustful fantasy or indulgence, and no lie is missed, overlooked, hidden, or forgotten. Whatever we "get away with" in life or manage to hide from other people, we must still face when the inevitable day comes that we are lifted up before Jesus Christ, the God of pure and perfect justice.
This reality has helped impel me at different times either to repentance or to avoid sin altogether. On one occasion in connection with a home sale, there was an error in the documentation, and I found myself in a position where I was legally entitled to get more money from the buyer. My real estate agent asked if I wanted to keep the money since it was my right to do so. I thought about facing the Lord, the personification of justice, and trying to explain that I had a legal right to take advantage of the buyer and his mistake. I couldn't see myself being very convincing, especially since I would probably be asking for mercy for myself at the same time. I knew I could not live with myself if I were so dishonorable as to keep the money. I replied to the agent that we would stick with the bargain as we all understood it originally. It is worth a great deal more to me than any sum of money to know that I have nothing to repent of in that transaction.
In my youth I once was negligent in a way that caused a minor injury to one of my brothers. I did not own up to my stupidity at the time, and no one ever knew about my role in the matter. Years later I was praying that God would reveal to me anything in my life that needed correction so that I might be found more acceptable before Him, and this incident came to my mind. I had forgotten about it, but the Spirit whispered that this was an unresolved transgression I needed to confess. I called my brother, apologized, and asked for his forgiveness, which he promptly and generously gave. My embarrassment and regret would have been less had I apologized when the accident happened.
It was interesting and significant to me that the Lord had not forgotten about that event of the distant past even though I had. Sins do not take care of themselves or simply fade away. Sins do not get "swept under the rug" in the eternal economy of things. They must be dealt with, and the wonderful thing is that because of the Savior's atoning grace, they can be dealt with in a much happier and less painful manner than directly satisfying offended justice ourselves.
We should also take heart when thinking of a judgment in which nothing is overlooked because this also means that no act of obedience, no kindness, and no good deed however small is ever forgotten, and no corresponding blessing is ever withheld.
