God is full of mercy.
Let's look at Genesis 3:8-13God asked Adam why he felt naked. Adam blamed God because God gave him woman and she is the reason he ate of the fruit.
So....
Adam blamed God for giving him the woman, and then blamed the woman who gave him the fruit to eat. So God inquired of the woman (to get to the bottom of it) what happened. She blamed the serpent (devil). So God told the serpent he would be cursed.
First of all God gave everyone the same opportunity to choose on their own. That's pretty amazing!
God knew we would be tempted and He knew the devil's ways but God gave us free-will choices.
God didn't make us programed to do as He chose or wanted.
He allows us to make our own decisions. If we go against what will help us and we chose a path of destruction, God allows it.
God also provides a way for us to come clean and back to Him and start over.
God is more than fair to us.
We are still blaming God for many things and we still struggle with taking responsibility.
