Yoda famously said that "Fear leads to anger. Anger leads to hate. Hate leads to suffering."
This seems to fit just a little too well with Romans 5:3-4, as rendered in some translations of the Bible:
Not only this, but we also rejoice in our sufferings, knowing that suffering works perseverance, and perseverance, proven character; and proven character, hope.
This could describe the sequel trilogy rather well. In particular, the reference to "hope" seems a little too close.
Lucas definitely borrowed heavily from other works. He also definitely lifted some things from the Bible, a fact acknowledged by current Lucasfilm employees. For example, the moon of Endor is likely a Biblical name, one made famous by the Witch of Endor. And much more was borrowed in general themes, of course: Anakin's virgin birth, Luke and Anakin as saviors born in the desert.
Are there any statements indicating that he may have been inspired by this passage?
