All the Elect, those Christ died for are free from sin and it's power to condemn them Rom 8:33-34
33Who shall lay any thing to the charge of God's elect? It is God that justifieth.
34Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us.
The Elect before the bar of God's Justice are Justified, because it is Christ that died. That is Christ died as being condemned in their place and stead. In fact the legal condemnation that they did incur in Adam Rom 5:16-18
16And not as it was by one that sinned, so is the gift: for the judgment was by one to condemnation, but the free gift is of many offences unto justification.
17For if by one man's offence death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ.)
18Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life.
Their condemnation, a real condemnation was not imputed to them, was not laid to their charge 2 Cor 5:19, but was actually laid to the Charge of Christ their Head and Represenative ! Yes, in and of thmselves they are condemned and guillty and sinful, but legally God had made a Covenant with their Surety before the foundation to charge Him with their awful crimes ! Christ could say of the sins of the elect imputed to Him Ps 69:5
5O God, thou knowest my foolishness; and my sins are not hid from thee.
So because of Christ, sin cannot condemn any for whom Christ did die for, His Elect, so they are dead to sin that way as well !
It can never be imputed to them, because it was once and for all imputed to Christ, and He bear them away Jn 1:29 Dan 9:24
