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.)
There are others. I'd commend the chapter on the Atonement in Come, Let Us Adore Him for a more complete explanation of this doctrine.
