What the Bible Says on Eve's Sin

If we take a carefull look at Genesis 2:15-18 we read (KJV at www.biblegateway.com):

"15 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. "

So, God gave Adam a direct order, and them, created Eve. The conclusion is that Eve did not receive a direct order from God, but she heard the order from Adam. Does that make her sin "smaller"?

Are we also waiting a direct commandment from God in order to obey? Does that mean if we do not follow an order from our pastor our sin is "smaller"? I don't think so...
