You can judge another based on conduct. They either do or do not do something. The conduct is observable, and therefore capable of being judged. Now, however, Christ moves the battleground inside a person. It is now in the heart. On such terrain as that, man is incapable of knowing, and therefore, of judging.
He really can save you. He has that power. He holds those keys. Even death and hell are conquered by Him. (Mosiah 15: 7-9.) But His victory cannot become ours unless we repent and turn again to Him.
It seems too simple a thing to achieve so great a result. It has always been like that. (1 Nephi 17: 41.) Look to Him and be saved. Keep His commandments. Repent. He can and will lead you from wherever you find yourself at present back into the light. It really does not matter what foolish traps you have surrounding you. So soon as you turn to face Him, He will direct you back safely. Repent and keep His commandments and they will bring you to Him.
“Verily, verily, I say unto you, I give unto you to be the salt of the earth; but if the salt shall lose its savor wherewith shall the earth be salted? The salt shall be thenceforth good for nothing, but to be cast out and to be trodden under foot of men.”
How can salt “lose its savor” except through contamination or impurities? When that is lost, the salt cannot preserve. There is no remaining savor. Then the salt is nothing more than common dirt, to be cast aside and trodden under foot.
This is the gentile predicament in the last days. They will, of course, lose their savor. They will reject the fullness offered to them. (3 Nephi 16: 10.) When they do, they will be torn apart and trodden under foot. (3 Nephi 20: 16; 3 Nephi 21: 12.)
Notice it is the Lord who “gives unto you to be the salt of the earth.” This condition is a gift from God. Through repentance, or turning to Him, you can receive this. Without repentance you cannot become the salt.
There are no private lives. Every life counts. Your private devotions are more important than your public notice. The salt which preserves may be unknown, likely is unknown, to most people. But if you are the salt, then your private life of devotion to the Lord is saving the lives of many others. The angels want to begin the harvest. They are impatient to begin reaping and cutting down the wicked now. (D&C 86: 5.) There is only time given because of a few who deserve more time to grow in faith before the harvest begins. (D&C 86: 6-7.) Your growth is all that is keeping the harvest from beginning now. Therefore, how you proceed has consequences far beyond your own life.
When wheat is ripe it will be protected. When tares are ripe they will be burned. But the tender plants worthy of preservation are the only ones allowed more time. (D&C 86: 4.) I advocate for them and realize how tenuous a position humanity itself is in at present. But you are the ones in the balance and for whom time is granted. How much longer no one knows, but your sins are not private. Your repentance is critical to all of creation. Do not think your life is your own. All of us have a share in your good works.
Do not think the Savior’s words are without cosmic significance. I define “cosmic” to include the cosmos or organized creation here. Even the earth itself longs to be freed from the burden of sin upon her face. (Moses 7: 48.) It is the Lord alone who has granted you time to repent. This current state of the creation we live is affected by the promise held in those who are repenting. As soon as that hope ends, and no further repentance is to occur, then the harvest will begin. Therefore, becoming salt has never been so important as it now is.
He speaks about the heart, rather than the hands and feet. Christ is speaking about beholding God, unlike the retreat Israel took from the offered opportunity at Sinai. (See D&C 84: 22-25.) He is returning to the time of Moses, when a higher way might have been chosen.
It is also interesting that what must be “pure” is the “heart.” There are so many other things one might measure. But what the Lord looks upon to determine purity is the “heart.”
How few hearts are pure before God. How rare a thing it is to contemplate such a person. How few we produce in this restoration of the Gospel. We remain as a people too low, too mean, too vulgar, too condescending to be called of God. No wonder we stumble and fall backward and many are taken in snares. (Isa. 8: 11-17.)
The standard applied to us is the standard we apply to others. This is repeatedly set out in scripture:
Alma teaching his son Corianton recorded: “Therefore, my son, see that you are merciful unto your brethren; deal justly, judge righteously, and do good continually; and if ye do all these things then shall ye receive your reward; yea, ye shall have mercy restored unto you again; ye shall have justice restored unto you again; ye shall have a righteous judgment restored unto you again; and ye shall have good rewarded unto you again. For that which ye do send out shall return unto you again, and be restored; therefore, the word restoration more fully condemneth the sinner, and justifieth him not at all.” (Alma 41: 14-15.)
