You are misapplying this passage.
The Law in this passage is the MOSAIC LAW:
12 Therefore, just as through one man sin entered the world, and death through sin, and thus death spread to all men, because all sinned— 13 (For until the law sin was in the world, but sin is not imputed when there is no law. 14 Nevertheless death reigned from Adam to Moses, even over those who had not sinned according to the likeness of the transgression of Adam, who is a type of Him who was to come.
Paul expounds upon this idea in 1 Corinthians 15:56
The sting of death is sin, and the strength of sin is the law.
Before the Law was given to Moses, ALL were condemned to death whether they sinned or not. As the scripture clearly states, "nevertheless, death reigned from Adam to Moses, even over those who had not sinned".
When The Law was given to Moses, it added the strength of individual condemnation to the personal act of sinning, and erected the scaffolding that prepared the way for the Christ.
Now that the mosaic law is fulfilled, that scaffolding became obsolete and passed away when the mosaic temple economy was dismantled, and the Christic Law, and the new and Everlsating Temple of His Body, are what remains.
Our sins no longer have the strength to prevent us from salvation, the way they did under the old covenant, mosaic system, which was the 'parenthesis' between Adam and Christ where individual sins had the strength to prevent salvation..
Sin is no longer the measuring stick God uses in determining who makes the cut the way it was under the old covenant mosaic system.
Today, you are ether "in Adam", as in the beginning, Condemned whether you sin or not, as scripture testifies was the case:
"Nevertheless death reigned from Adam to Moses, even over those who had not sinned"
or
You are "In Christ", Saved, even though you are a sinner.
In Fact, only sinners get saved!
You can live a perfectly sinless life, and that will not get you into heaven if you "pass" on the gift of salvation through faith in Jesus Christ, bought and paid for on the cross.
Not sinning, By itself, is absolutely powerless to earn you eternal salvation.
Conversely, There is not even one sin that is more powerful than Christ's atoning sacrifice.
Not even one.
“You are misapplying this passage.
The Law in this passage is the MOSAIC LAW:
12 Therefore, just as through one man sin entered the world, and death through sin, and thus death spread to all men, because all sinned— 13 (For until the law sin was in the world, but sin is not imputed when there is no law. 14 Nevertheless death reigned from Adam to Moses, even over those who had not sinned according to the likeness of the transgression of Adam, who is a type of Him who was to come.”
The Mosaic law is included in God’s law therefore it is all God’s law. Moses was just the instrument through whom the law was delivered but what Romans 5:13 is stating is that even though all sin, those are unware of their sin are not held accountable. We are only held accountable for that which we are made aware which what Paul also went on to explain:
“I had not known sin but by the law: for I had not known lust, except the law had said, Thou shalt not covet” (Rom. 7:7) going on to explain that “sin, taking occasion by the commandment, wrought in me all manner of concupiscence, For without the law sin was dead.” (Rom. 7:8)
He was at that moment held accountable for sin, standing condemned before the law because even though he wanted to keep the law and even tried to do so to the best of his ability, the inherent sinful nature that was in him, as is inherent in all of us, caused him to fall short and prevented him from keeping the law perfectly and it is because of sin that none are able to keep the law and therefore, anyone relying on the law for salvation is disqualified from entering into the Kingdom of Heaven.
“Before the Law was given
to Moses, ALL were condemned to death whether they sinned or not. As the scripture clearly states, "nevertheless, death reigned from Adam to Moses, even over those who had not sinned.’”
No one who has not sinned is condemned to death because the wages of sin is death, (Rom. 6:23) therefore if all die it is because all have sinned. We may not have sinned in the same way that Adam sinned, but because of the sinful nature that we inherited because of Adam’s transgression, we all sin and therefore we all die.
“When The Law was given to Moses, it added the strength of individual condemnation to the personal act of sinning, and erected the scaffolding that prepared the way for the Christ.
Now that the mosaic law is fulfilled, that scaffolding became obsolete and passed away when the mosaic temple economy was dismantled, and the Christic Law, and the new and Everlsating Temple of His Body, are what remains.”
The law has no power to condemn us because sin can no longer keep us from salvation for those of us who are in Christ, but just because we are under the law of grace does not give us permission to continue living in the sin we say we have repented from:
“Shall we continue to sin that grace may abound? God forbid. How shall we, that are dead to sin, live any longer therein…reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord. Let not sin therefore reign in you mortal body, that ye should obey it in the lusts thereof. Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God as those that are alive from the dead, and your members as instruments of righteousness unto God.” (Rom. 6:1-2, 11-13)
“For if we sin willfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins, But a fearful looking for of judgment and fiery indignation which shall devour the adversaries.”
“Sin is no longer the measuring stick God uses in determining who makes the cut the way it was under the old covenant mosaic system.”
It takes more than just mere lip service or a profession of faith to be saved. Our acceptance of Jesus and our trust in Him for our salvation must be done in sincerity and the evidence of that sincerity is manifested by a transformed life. Sin may not be the measuring stick God uses in what makes the cut the way it was under the Old Covenant system, No one ever really could make the cut even then. Even the Old Testament saints knew that they fell short of keeping the law because of sin no matter how hard they tried to keep it, which is why faith was what they still had to live by (Hab. 2:4) trusting that the grace of God would meet them where they fell short But God still measures the sincerity of each heart.
“You can live a perfectly sinless life, and that
will not get you into heaven if you "pass" on the gift of salvation through faith in Jesus Christ, bought and paid for on the cross.
Not sinning, By itself, is
absolutely powerless to earn you eternal salvation.”
It is impossible to live a perfectly sinless life to begin with because all have sinned and fallen short of the glory of God (Rom. 3:23) for if it were possible to go through life and not commit a single sin in any way shape or form, then our own righteousness would be sufficient enough to grant us entry into Heaven, but because of sin, our righteousness is not sufficient enough and that is why we rely on the righteousness of Christ who gave Himself on our behalf as that ultimate once and for all sacrifice for sins so that we who place our trust in Him would be forgiven of all of our sins and thereby be given salvation for all eternity and granted everlasting life.
