Sin not being imputed !
A Glorious benefit and accomplishment of the atoning death of Christ, that religionist cant receive is this, those Christ died for sin cannot and will not be imputed to them, or charged to them, for they all are the blessed man here Rom 4:8
8 Blessed is the man to whom the Lord will not impute sin.
Sin is not imputed or charged to any sinner Christ died for, for His Blood alone cleanses them from all sin 1 Jn 1:7
7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
Heb 1:3
3 Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high:
The word purge here is from the word cleanseth in 1 Jn 1:7, they are talking about the very same thing as the result of Christ's death !
Now lets understand something, all of Gods Elect, those Christ died for, before and after conversion have sin in them experimentally, and at times it reigns in them, in their flesh and members Rom 7, such sins as these listed but not limited to them Mark 7:20-23
20 And he said, That which cometh out of the man, that defileth the man.
21 For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders,
22 Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness:
23 All these evil things come from within, and defile the man.
But the good news for them Christ died for is this, even though these sins may harass them, even overcome them, bring them into captivity, give us great pleasure in the flesh, deprive them of sweet fellowship and communion with God, nevertheless God does not charge them to their account, and God sees them still as perfectly righteous, holy and unblameable in His sight, that's the hope of the Gospel Col 1:21-23
21 And you, that were sometime alienated and enemies in your mind by wicked works, yet now hath he reconciled
22 In the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight:
23 If ye continue in the faith grounded and settled, and be not moved away from the hope of the gospel, which ye have heard, and which was preached to every creature which is under heaven; whereof I Paul am made a minister;
And True God given Faith rests in and believes this Blessed Truth !
For the Just shall live by Faith ! 48
