I see, but that is nowhere in the text of Romans 7 does it imply that we can blame it on the Devil, or, that the Devil made us do it.The question is not blame but causation. We do not sin solely because we want to. There are other forces that are brought to bear on us. We are indeed culpable, but the reason we sin is because of sin living in us, separating us from God, our only source of power over sin. Is is ultimately because of Satan's deception that we sinned, and we wouldn't have done it without him. He is the Deceiver, and is culpable for his role.
Scripture says we sin when we are drawn away by our own lust, James 1:14, it doesn't say blame it on the Devil, or imply that it is his fault.
"We?" So you do believe in original sin?We are culpable because we willingly believe his deception rather than God.
Yet that apparently contradicts your former argument.Being deceived is not to be forced against our will; but being deceived is the direct cause of our wilful choice.
