@neologist,
They didn't 'sin'. They ate of the tree which God told them that in the day they ate of it, which could be 1000 years with The LORD (2 Peter 3:8), they would surely die.
2 Peter 3:8 "But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day."
They did, however, transgress, or go against what The LORD God told him.
Oh get this. Did God tell the 'woman' Eve, she could not eat, or did God tell the man, Adam, that 'he' was not to eat?
Genesis 2:15-18 "And the LORD God took the man, and put him into the garden of Eden to dress it and to keep it.
16 And the LORD God commanded the man, saying, Of every tree of the garden thou mayest freely eat:
17 But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.
18 And the LORD God said, It is not good that the man should be alone; I will make him an help meet for him."
Genesis 3:1 "Now the serpent was more subtil than any beast of the field which the LORD God had made. And he said unto the woman, Yea, hath God said,
Ye shall not eat of every tree of the garden?"
So although they didn't really 'sin', God created the man to be the head of the woman and to keep her and help her as Christ does to and for His Church, which is His Body.
I'm thinking 'head' to mean, Provider/Benefactor/Keeper, etc..
So if the woman, Eve, did not transgress or 'sin' against The LORD God, what happened?
Genesis 3:2-3 "And the woman said unto the serpent, We may eat of the fruit of the trees of the garden: 3But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die. "
If The LORD God did not tell the woman she could not eat, then from whom did she receive the instruction, 'God hath said, Ye shall not eat of it'...?
The LORD God,
God
The LORD
(J)esus.
They are all separate persons.
The LORD God is YHWH and elohim, hence 'YHWH=Elohim'
