Adam was not created under any old covenant.
Indeed he was "
cursed is very one who does not obey" is the Old Covenant according to Galatians 3.
Genesis 2 "
for the in day you eat - you shall surely die".
Adam was in "purest form" of the Old Covenant agreement. "
Obey and live" ... this is irrefutable.
So also are you until you accept the Gospel - the New Covenant.
Bible details matter.
Yes, then when Adam sin, his sin was a transgression. Because he sinned against law.
Obviously. And as the Bible says - sin is by definition "transgression of the Law" 1 John 3:4
Adam could not curse, or take God's name in vain, or do violence or ... all of that would be sin.
God says to Cain "
SIN is crouching at your door but you must master it" -- sin of what "eating the wrong fruit"???
Your rejection of the details of scripture places you in opposition to every Gospel statement known to every Bible scholar on Earth when it comes to what is sin.
Death reigned because all were sinners.
And sin by definition is "
transgression of the LAW" 1 John 3:4
Even though they were not under law.
Creative writing "again" -- no text says that.
But the Bible DOES say this --
See Romans 4:15 - "where there is
no Law there is no SIN" Romans 5:13
See Romans 5:12 - there WAS
SIN starting with Adam. 12 Therefore, just as
through one man sin entered into the world
See 1 Tim 2:14 -
SIN starting with Eve
See Genesis 4 -
SIN even at the time of Cain
see 1 John 3:4 -
SIN IS (by definition) "
Transgression of the LAW" even in the NT
These are basic Bible facts agreed to by C.H. Spurgeon, Baptist Confession of Faith, Westminster Confession of Faith etc.
Essentially every Christian group on planet Earth admits to this basic fact about the Ten Commandments as the moral law of God written on the heart in the OT - starting in Eden.
Consider paying attention to the "Bible details"
Sin existed before the giving of the law on stone Law,
but law in the form of God's WORD existed before "writing on stone" thus SIN existed before the formal "writing on stone". . That is why death reigned. It reigned over them that were under the old covenant "obey and live" and "Sin IS transgression of the LAW".
As for "obedience" to LAW, and COMMANDMENTs and STATUTES before the "writing on stone" of God's Word well - Genesis 26 says it all.
Genesis 26:3...and I
will establish the oath which I swore to your father Abraham.
4 I will multiply your descendants as the stars of heaven, and will give your descendants all these lands; and by
your descendants all the nations of the earth shall be blessed; 5 because Abraham obeyed Me and
kept My charge, My commandments, My statutes and My laws.”
