Justjustice, justify are synonyms with the terms “righteous”, “righteousness”, “make righteous”.
Faith synonyms with the word belief.
We are justified by faith (we are made righteous by faith)
Lawdon’t understand the word law in human fashion, i.e., a regulation about what sought of work must be done or must not be done. Those are human laws; you satisfy the demands of the law by works, whether your heart is in it or not.
Gods judges what is in the heart. Therefore his law also demands on the depth of the heart and does not let the heart rest content in works done apart from the depth of the heart.
All human beings are called liars (PS 116) since none of them keeps or can keep God’s law from the depth of the heart. Everyone finds inside himself an aversion to good behavior and a craving for evil. Where there is no face desire for good there the heart has not set its self on Gods law. There also sin is surely to be found and the deserved wrath of God, whether a lot of and an honorable life appear outwardly or not.
Sin means not only external works of the body but also all those movements within us which bestir themselves and move us to do the external works namely, the depth of the heart with all its powers.
Therefore the word ‘do’ should refer to a person’s completely falling into sin. In particular, the scripture sees into the heart, to the root and the main source of all sin: un9belief in the depth of the heart. # Thus, even as faith alone makes just and brings the spirit and the desire to do good external works, so it is only unbelief which sins and exalts the fresh and brings desire to evil external works. That’s why only unbelief is called sin by Christ, as he says in john 16,
“The spirit will punish the word because of sin, because it does not believe in me.”
Before good or bad works happen, which are the good or bad fruits of the heart, there has to be present in the heart either faith or unbelief, the root, sap and the chief power of all sins. That is why, in the scriptures, unbelief is called the head of the serpent and of the ancient dragon which is the offspring of the woman i.e. Christ, must crush, as was promised to Adam.
Grace and gifts these defers in that; grace actually denotes Gods kindness or favour which he has towards us by which he is disposed to pour Christ and Spirit with his gifts into us. The gifts and the spirit increases daily in us, yet they are not complete, since evil desires and sins remain in us which war against the spirit. Grace makes us accounted completely just before God.
God’s grace is not divided in bits and pieces are the gifts, but grace takes us up completely just before just before God’s favour for the sake of Christ, our intercessor and mediator, so that gifts may begin their work in us.
Faith  is a work of God in us, which changes us and brings us to birth a new from God. It kills the old Adam, makes us completely different people in the heart, mind, senses and all our powers and brings Holy Spirit with it.
It is impossible that faith ever stop doing well. Faith does not ask whether good works are to be done but before it is asked it has done them. It is always active. Whoever doesn’t do such works doesn’t have faith, he glops and searches about him for faith and good works are. Even so, he chatters on with great many words about faith and good works.
Faith is a living, unshakable confidence in God’s grace it is so certain that someone would die a thousand times for it. This kind of trust in and knowledge of gods Knowledge makes a person joyful, confident and happy with regard to god and all creatures. This is what the Holy Spirit does by faith.
Through faith a person will do well, to everyone without cohesion, willfully and happily; he will serve everyone, suffer everything for the love and praise of God who has shown him such grace. Ask God to work faith in him; otherwise you will remain eternally without faith, no matter what u try to do or fabricate.
Now “justice” is just such a faith. It is called Gods justice or that justice which is valid in Gods sight, because it is God who gives it and reckons it as justice for the sake of Christ our mediator. It influences a person to give to everyone what he owes him. Through faith a person becomes sinless and eager for God’s command. Thus he gives god the honor due him and pays him what he owes him. He serves people willingly with the means available to him. In this way he pays everyone is due. Neither nature nor freewill nor our own power can bring about such a justice, for even as no one can give him faith, so too he cannot remove unbelief. How can he then take away even the smallest sin? Therefore, everything which takes place outside faith or in unbelief is lies, hypocrisy and sin; no matter how smoothly it may seem to go.
Flesh (john 3) i.e. the whole human being with body and soul, reasons and senses, since everything in him tends towards the flesh. That’s why you shun know enough to call that person ‘fleshly’ who, without grace, fabricates, teaches, and chatters about hi spiritual matters. (Gal 5). Through flesh the law is weakened, unbelief.
A person is flesh who inwardly and outwardly lives only to do these things which are of use to the flesh and to temporal existence.
A person is ‘spirit’ who inwardly and outwardly lives only to do those thing which are of use to the spirit and to the life to come.
Grace and free will
Free will is unable to begin or to perfect any true and spiritual good without grace. Grace means by it that which is the grace of Christ and that which belongs to regeneration.
This grace is simply and absolutely necessary for the illumination of the mind, the due ordering of the affection and the inclination of the will to that which is good. It is this grace that operates on the mind the affection and the will; which infuses god thought into the mind, inspires good desires into the actions, and bends the will to carry into execution good thought and good desires. Tis grace goes before, accompanies and follows, it exits assist, operate that we will and cooperate lest we will in vain. It averts temptations, assists and grants succor in the midst of temptation, sustains man against the flesh, the world and Satan and in this great contest grants to man the enjoyment of the victory. It raises up again those who are conquered and have fallen, establishes and supplies them with new strength and renders them more cautious. This grace commences salvation, promotes it and perfects and consummates it.
The mind of a natural and carnal man is obscure and dark that his affections are corrupt and inordinate, that his will is stubborn and disobedience and that the man himself is dead in sin.
