Genesis 3:13

"Then the Lord God said to the woman, 'What is this you have done?'
"The woman said, 'The serpent deceived me, and I ate.'"
Genesis 3:13

Now God is giving the woman a chance to hear her side of the story, and she follows the man's example and shifts the blame right on over to the serpent.  "It's not my fault.  I was tricked." 

Maybe this is why man was placed in a authority - when the sin occurred it says the woman was tricked, not the man, but the woman followed his lead when it came time to fess up.  That can make it even harder to do the right thing, when those around us, especially those we look up to, are pointing the blame our way.

God, give us strength to confess our sins even when those stronger than we are fail to do so.
