Actually you can. Paul could have been referencing the Jews not having any special dispensation of salvation because they were Jews only, that they like the Gentiles were "by nature" children of wrath. Another possibility is the fact God can have nothing to do with our natures which became affected by the fall hence the curse of death being God's wrath against humanity.
A sinner is defined as one who sins. You are not defined as a murderer until you commit murder (either physically or in the heart). You are not a thief unless you steal. You are not a molester unless you molest someone. Being deemed a sinner just because you were conceived is far fetched and false. You have redefined the very word.
I haven't redefined anything. In fact, you are the one monkeying around with words and trying to change the meaning. Of course you would, given that this passage flatly and plainly denies your position. The only choices you have left are to accept the clear language of the bible or to be dishonest with that language. You've chosen the latter.
What does "by nature" mean? Well, it doesn't mean by action, that's for sure. For instance, a lion is a predator by nature. Whether that lion lives long enough to stalk and kill prey, it is still a predator by nature. It's very nature is inclined to stalk and kill prey. That is what lions do. If that lion lives long enough, that's what he'll do. Same thing with man. He is by nature a sinner. That is what he is. If he lives long enough, he'll sin by action. Why? Because he is a sinner by nature. That's why every single man and woman in history save the Son of God have sinned.
Paul is talking to regenerated people. They've been quickened by God, made alive. Previously they were dead in sins. Paul describes that condition as following the course of this world, the prince of the power of the air, the spirit that now worketh in the children of disobedience. While Paul is describing this condition he uses the plural pronoun you, referring to his audience. But then he does a most curious thing - in the next verse he says, "among whom also
we all had our conversation (way of living) in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath even as others." Paul is not just talking about these Gentile Ephesians, he includes himself in this, and he is a Jew. Jew and Gentile are both included in this, and it should be manifest that he is talking about all regenerated people. In other words, prior to regeneration we were all by nature the children of wrath. We were dead in sins, following the course of this world, following Satan, living in the lusts of our flesh, and were by nature children of wrath. This is the natural condition of man. That is because man is a sinner by nature and needs the great redemptive work of Jesus Christ.
You ever wonder why a parent doesn't have to teach a child to be bad? If one ever wants a lesson in depravity, just observe kids. They just naturally seem to be bad, and a parent has to work hard to teach them right. I love my son more than I can say, but he is a sinner, plain and simple. That boy is only two years old, but I'll tell you he'll do wrong in a second and he knows he's doing wrong. My son is just like me in that he is a sinner. He didn't become a sinner, he was born a sinner. The good news is Jesus is a friend of sinners. I firmly believe the bible teaches that the Lord Jesus saves all His people the same way.
