Rom 3:
19Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.
The scripture teaches that all men [ jew and gentile] are inwardly corrupt by nature, and guilty [ of this corruption ] before God, all men are totally depraved before God.
In culminating the the summary universality of corruption in rom 3: 9-19, Paul states that the entire world of men stands guilty of corruption before God, from the religious jew to the pagan gentiles.
It should be made clear however that no matter how depraved and guilty the elect of God are by nature, whether jew or gentile, they from a Judicial Legal standpoint God ward are not guilty, never condemned by the Law of God.
For the legal condemnation and guilt they [ the elect] deserve for their depravity in common with all mankind, has been imputed to Christ, and not imputed unto them.
The Lord Jesus Christ became legally guilty and condemned [ by imputation] for their sins, their depravity. The elect of God by nature are children of wrath [ depraved] even as others, but they are preserved through their depravity, to be quickened, that is made alive, because they were of the election of grace, and the guilt of their depravity [ all those horrible items outlined in rom 3:10-18] has been borne by Christ, and they have been set free from the law of sin and death.
So guilt in rom 3 19 as it pertains to the elect, is depravity guilt, of which sooner or later they will be convicted of [ Jn 16:8] and it is not legal condemnation guilt which Christ received for them and on their behalf.
