or by the Law is the Knowledge of sin !
rom 3:
20Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
Through the Law, No Flesh [To include Adam ] shall be Justified in His Sight.
Its always been,Through the Law is or comes the Knowledge of sin. Paul says:
I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.
For that was the purpose for the Law, and it was the purpose for the first head of mankind Adam.
Did not God create Adam in flesh and gave Him the Law ! Thou shalt not eat of the Tree of the knowledge of good and evil ! That was God's Law for Mankind right there. Believe it or not, this law was given to show him or teach him that, even though he was created upright, he was a sinner and could not in his flesh be justified before God ! It showed him that he was yet but weak flesh, that he was but vanity ps 39:5
verily every man at his best state is altogether vanity. Selah. This includes first of all Adam. The word man here is Adam in the original.
But now lets not get confused what I am stating here, for Adam was not yet a Transgressor until after He actually sinned [through eve] so thats when Transgression entered into the world. 1 tim 2:
14And Adam was not deceived, but the woman being deceived was in the transgression. Initially !
also rom 5:
14Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam's transgression, who is the figure of him that was to come.
But thats why they sinned, why they transgressed,because in the flesh, they were already sinners, so thats what sinners do when confronted with the Law of God. Sinners sin, they Transgress.
This was God's purpose all along, in order that the seed of the women, and His blessed hope may be now revealed to the world. You see Christ death for sin had been determined before the world began, before Adam and Eve were created !! It was part of God's predetermined counsel acts 2
23Him, being delivered by the determinate counsel and foreknowledge of God, ye have taken, and by wicked hands have crucified and slain:
rev 13:
8And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world.
lk 22:
22And truly the Son of man goeth, as it was determined[before the world began]: but woe unto that man by whom he is betrayed!
1 pet 1:
20Who verily was foreordained before the foundation of the world, but was manifest in these last times for you,
eph 3:
11According to the eternal purpose which he purposed in Christ Jesus our Lord:
When do you think this was determined ?
So Adam was formed out of the dust of the ground for this eternal purpose.
He was given the law [Thou shalt not eat of the Tree of the knowledge of good and evil] to show him he was a sinner, in need of the one who was going to execute the Eternal Purpose by going to the cross [the seed of the woman]You see it was all a foreordained purpose from Eternity..
