Look carefully upon this from Romans 5:
12Therefore, just as
sin came into the world through one man, and death through sin, and so death spread to all men because all sinned—
13for sin indeed was in the world before the law was given, but
sin is not counted where there is no law.
14Yet death reigned from Adam to Moses, even over those whose sinning was not like the transgression of Adam, who was a type of the one who was to come.
15But the free gift is not like the trespass. For if many died through one man’s trespass, much more have the grace of God and the free gift by the grace of that one man Jesus Christ abounded for many.
16And
the free gift is not like the result of that one man’s sin. For the judgment following one trespass brought condemnation, but the free gift following many trespasses brought justification.
17For if, because of one man’s trespass, death reigned through that one man, much more will those who receive the abundance of grace and the free gift of righteousness reign in life through the one man Jesus Christ.
18Therefore, as
one trespass led to condemnation for all men, so
one act of righteousness leads to justification and life for all men.
19For as by the one man’s disobedience the many were made sinners, so by the one man’s obedience the many will be made righteous.
20Now the law came in to increase the trespass, but where sin increased, grace abounded all the more,
21so that,
as sin reigned in death, grace also might reign through righteousness leading to eternal life through Jesus Christ our Lord.
Ultimately, the death here is both physical and spiritual. But because of the law (that which was delivered to Moses millennia after Adam, the sin now pays a wage, yet still death reigned from Adam to Moses, because even though the Law was not given, sin still death was still the result of sin.
Interesting that Paul states that "ONE trespass led to condemnation for all men, so ONE act of righteousness leads to justification and life for all men."
There are those who limit the atonement and therefore cannot take verse 18 as strictly interpreted. Yet, if they would be give way to the presentation and that of John as being factually based, they would see the truth that it remains belief is the single key.
See how starting in verse 15 the free gift is NOT like the trespass? For does it not say that "the grace of God AND the free gift by the grace of that one man Jesus Christ abounded for many" and note it was not for ALL!
Again, the issue resolves to that of belief!
ALL have the blood shed that "leads to justification and life", but most do not believe, for they refuse, turn away, and will not be redeemed and will spend eternity in the flames.
Now this post is far from Galatians 3, but for readers who get confused in the discourse, this is a foundational truth.
Christ came and died for sinners (all), yet not all sinners will be redeemed because such are not given the ability to believe, because they cannot embrace the light and turn away in desires of the flesh, the lusts of the world, and the pride of this life.
