That's untrue and just words in a book. The ten commandments etc are obviously just man made since they didn't apply to Abraham and his ancestors.
Which is why was it was OK for Cainan to kill his brother, given that his god even protected him from retribution when he moved to Nod and shacked up with one of the Nod girls (Gen 4), and why it was OK for Abraham to butcher and cook his son as a sacrificial meal for his god even though he subsequently butchered an old ram instead as a meal for his god.
And why it was OK for Abraham and Noah to shack up with their sisters and for Abraham's nephew to sexually assault his daughters.
Then we have Gods Word again, that disagrees with your words that are not Gods Word but your words...
EXODUS 20:1-17
1, AND GOD SPOKE ALL THESE WORDS SAYING,
2, I am the LORD your God, which have brought you out of the land of Egypt, out of the house of bondage.
3, You shall have no other gods before me.
4, You shall not make to you any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth.
5, You shall not bow down yourself to them, nor serve them: for I the LORD your God am a jealous God, visiting the iniquity of the fathers on the children to the third and fourth generation of them that hate me;
6, And showing mercy to thousands of them that love me, and keep my commandments.
7, You shall not take the name of the LORD your God in vain; for the LORD will not hold him guiltless that takes his name in vain.
10, But the seventh day is the sabbath of the LORD your God: in it you shall not do any work, you, nor your son, nor your daughter, your manservant, nor your maidservant, nor your cattle, nor your stranger that is within your gates:
11, For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: why the LORD blessed the sabbath day, and hallowed it.
12, Honor your father and your mother: that your days may be long on the land which the LORD your God gives you.
13, You shall not kill.
14, You shall not commit adultery.
15, You shall not steal.
16, You shall not bear false witness against your neighbor.
17, You shall not covet your neighbor's house, you shall not covet your neighbor's wife, nor his manservant, nor his maidservant, nor his ox, nor his ***, nor any thing that is your neighbor's.
1. Abraham knew Gods law and commandments before Sinai
GENESIS 26:5
5
, Because that Abraham
obeyed my voice, and
kept my charge, my commandments, my statutes, and
my laws.
As posted earlier according to the scriptures, before the written Word of God was the spoken Word of God. According to the scriptures Gods people have always had Gods laws through the spoken Word of God handed down through the generations to the parents children.
According to the scriptures Gods law gives us the knowledge of what
SIN is when it is broken.
SIN is defined in the scriptures as breaking Gods law and not believing and obeying Gods Word (Romans 3:20; 1 John 3:4; Romans 7:7). Without Gods law there is no knowledge of what
SIN is.
2. CAIN knew what
SIN was (transgression of the law and not believing and obeying Gods Word)
GENESIS 4:7
7, If you do well, shall you not be accepted? and if you do not well,
SIN LIES AT THE DOOR. And to you shall be his desire, and you shall rule over him
3. The inhabitants of Sodom understood what
SIN was (broke Gods law)
GENESIS 18:20
20, And the LORD said, Because the cry of Sodom and Gomorrah is great, and because
THEIR SIN IS VERY GRIEVOUS.
4. Joseph knew that adultery was
SIN
GENESIS 39:7-9
7, And it came to pass after these things, that his master's wife cast her eyes on Joseph; and she said, Lie with me.
8, But he refused, and said to his master's wife, Behold, my master wotteth not what is with me in the house, and he has committed all that he has to my hand;
9, There is none greater in this house than I; neither has he kept back any thing from me but you, because you are his wife:
HOW THEN CAN I DO THIS GREAT WICKEDNESS AND SIN AGAINST GOD?
You do err not knowing Gods Word while making excuses for sin and unbelief.
Take Care.
