A just person is one who is in agreement with morality and goodness. He is one who treats people in a way that is morally good. He is reasonable and proper in the sight of the Lord. He faithfully reproduces and resembles the First and Original One.
The way of uprightness is to always behave in an honest way and conform to high moral standards. We are therefore just (morally good) when we behave according to the high moral standards set by God.
God is the most upright and morally good being in the universe. It is by His high standard that we are judged in our uprightness. More importantly, it is God who judges us. We are not to judge one another, nor are we even to judge ourselves, who are our own worst critics. We can take comfort that our Father, who is also the most loving, kind, merciful and gracious being in the universe, will be our judge, for he will weigh not just our imperfect actions but also the intentions of our hearts.
Our hope can be even greater when we realize that the Father has given all judgment to His Son (see John 5:27). It is even more comforting to know that the One who has paid for our sins and taken upon Himself our griefs, sorrows, and pains – who knows us inside and out better than we know ourselves and loves us in spite of it all – will be our kind and merciful judge.
When I kneel before my Father each day and acknowledge my weaknesses, imperfections and shortcomings, and show Him all my fears and pride and selfishness, I do so in the name of Christ because Christ has promised to deflect the Father's gaze from my wretchedness. Even while I "[smite] upon [my] breast, saying, God be merciful to me a sinner" (Luke 18:13), the Savior stands by me and pleads my cause. He says in effect, "Father, don't look at this wretched man as he is now. Look at me, and know that I will eventually raise him up to be like me. You are pleased with me. Someday you will be pleased with this one who today is so flawed. Spare him while he learns to come unto me. It is not an easy task for either of us, my brother and me. But he is willing and I am capable, and I will eventually get him fixed up" (see D&C 45:3-5).
O, may my way be uprightness until I become just like my Savior!
