Yes, let us let the readers see what methods you must use in a failed attempt to match your teaching with the Scriptures in regard to what causes spiritual death. Here Paul says that "death passed upon all men, for that all have sinned":
"Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned" (Ro.5:12).
Spiritual death comes as a result of a person's sin. But since that doesn't fit your mistaken view you simply add the following words in bold:
"Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned IN ADAM" (Ro.5:12).
1 Cor. 15:22 For as in Adam all die,"
What happened to "all" in Adam? "by the offence of one many BE DEAD" - "by one man's offence many were MADE SINNERS."
Paul does not say by the OFFENCES PLURAL of MANY PLURAL many "BE DEAD" or many were MADE SINNERS - but that is what your false doctrine requires Paul to say to fit your interpretation of Romans 5:12.
Your interpretation of Romans 5:12 requires it to mean "by one man LAW entered into the world" but it does not say or mean that as the following context shows.
You jerk Romans 5:14 out of context and make it fit your theory and then choose a translation to harmonize with your error. His argument is very simple and the over all context keeps on repeating the point of this argument - "BY ONE MAN'S OFFENCE" not by MANY MEN'S OFFENCE as you interpretation demands.
The only LAW revealed by God to man was Genesis 2:16 and only Adam violated that law and N

THER HUMAN BEING violated that law but Adam and it is through that ONE MAN and his ONE OFFENCE many "BE DEAD" many be "MADE SINNERS" and many were condemned and the proof is that N

THER LAW was revealed to men living between Adam and Moses and yet all living between Adam and Moses died and so death must be traced back to violation of that ONE REVEALED LAW by ONE MAN.
Secondly, since all die who are incapable of having sinned willfully and intentionally (infants and mentally handicapped) then the only cause of their death must be traced bact to ONE MAN'S OFFENCE of that ONE REALED LAW in Geneis 2:16.
To further support my view according to Paul's version we can see that just two chapters later he makes it plain that "death" resulted from his sin against the law:
"For I was alive without the law once: but when the commandment came, sin revived, and I died. And the commandment, which was ordained to life, I found to be unto death. For sin, taking occasion by the commandment, deceived me, and by it slew me" (Ro.7:9-11 )
Since Paul remained alive "physically" when he wrote those words he was speaking of a "spiritual" death.
But since this does not fit your mistaken ideas you must somehow explain those words away. Here is your failed attempt to do that:
According to your idea Paul was "alive" unto God as he saw his religious life. It was this "knowledge" which died.
Even though Paul said that he died and the law slew him you say that he did NOT die at all but instead it was only his "knowledge" which died!
If there was ever a case of nightmare exegesis this is it! ).
Unfortunately for you my exegesis is the truth! You ignore context of this passage which follows Romans 7:1-6 where Paul establishes that Christians are "DEAD" to the law through the body of Christ and therefore Paul's aim is to prove that the law law cannot sanctify a person any more than it can justifiy a person but only reveal sin and condemn that person.
To prove this, he first must establish that the problem is not in the law but in the person attempting to obey the law. This problem exists in that person both before (Rom. 7:7-13) and after becoming a Christian (Rom. 7:14-25) and so the law can neither justify (Rom. 7:7-13) or sanctify (Rom. 7:14-25) a person but both are the acts of the Holy Spirit (Rom. 8:1-27). So you are ignorant of the context and pervert it.
In Romans 7:7-13 the law cannot justify, provide life, provide righteousness, provide holiness even though the law is just, rightoues and good (vv. 7,12). The problem is in man not in the law.
Paul is speaking from the time of birth to the time he was as a Religous lost Rabbi in Romans 7:8-11 as it was during that time frame he reveals how he viewed himself in relationship to the law. Philippians 3:4-6 demands this is how he viewed his relationship with the law between birth and salvation:
Philip. 3:4 ¶
Though I might also have confidence in the flesh. If any other man thinketh that he hath whereof he might trust in the flesh, I more:
[birthright]
5 Circumcised the eighth day, of the stock of Israel, of the tribe of Benjamin,
[life from birth to salvation]an Hebrew of the Hebrews; as touching the law, a Pharisee;
6 Concerning zeal, persecuting the church; touching the righteousness which is in the law, blameless.
He saw himself as ALIVE TO GOD through "righteousness is in the law, BLAMLESS" thus justified for eternal life under law.
In Romans 7:8-11 he describes how his view of the law IN REGARD TO HIMSELF changed. Romans 7:8-11 is the transformation that occurred somewhere on the Road to Damascus just before his conversion. This is what Jesus was referring to when he told Saul "It is hard for thee to kick against the pricks"
What he formerly thought was the source of LIFE became DEATH when he was brought to understand what the law really included - "the law is SPIRITUAL" and it was the tenth commandment that broke the barrier in his mind from purely an EXTERNAL application of law (from whence he perceived himself as "blameless") to an INTERNAL application of the law which brought condemnation and death to his understanding instead of blamelessness and life as previously perceived by him.
Now this is the truth and you will stand before God and answer for rejecting it and you will reject it unless God opens your eyes.
