God created everything "good," so we are told in the Bible. Sin entered into the creation, through Mans' misuse of his God given free will, and sin corrupted the creation.
Gods' plan is to redeem His creation from sin, and that includes us.
We still have free will, we still have a choice. Blaming God for a corrupted world with its wars, cancer, hunger, earthquakes and tsunamis etc, is to miss the point that the world is now, "damaged goods," and although we cannot change the world, we can change our little bit of it. To do that, we have to be open to Gods' presence in our hearts, and not deny Him, then by the power of His Holy Spirit, we can find the way forward, living less for ourselves and more for others.
