What does God will not impute sin mean ?
Ps 32:1-2
Blessed is he whose transgression is forgiven, whose sin is covered.
2 Blessed is the man unto whom the Lord imputeth not iniquity, and in whose spirit there is no guile.
Rom 4:7-8
7 Saying, Blessed are they whose iniquities are forgiven, and whose sins are covered.
8 Blessed is the man to whom the Lord will not impute sin.
This is the result for all them Christ died, their sins being transferred to Him, hence they are truly blessed, and what it also means is that all their works/sins of the flesh such as these found here Gal 5:19-21
19 Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
20 Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
21 Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
Eph 5:3-5
3 But fornication, and all uncleanness, or covetousness, let it not be once named among you, as becometh saints;
4 Neither filthiness, nor foolish talking, nor jesting, which are not convenient: but rather giving of thanks.
5 For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God.
Rom 1:29-32
29 Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,
30 Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,
31 Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:
32 Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.
These sins of theirs, before and after conversion, no matter how often committed by them, they are never imputed or charged to them, for God sees them even in the midst of all these their transgressions, He sees them as being those in whose spirit there is no guile Ps 32:1-2, because God hath charged all them sins and their accompanying guilt to Christ, and so in Divine Justice they cannot be charged unto them, So most blessed are they, and thats what that means, that God will not impute sin to them, They're the Truly Blessed Ones of mankind !
