All are sinners: both infants and adults; both unsaved and saved.
For there is none righteous, no not one.
No, little children are not sinners;
Rom 9:11 (For the children being not yet born, neither having done any good or evil, that the purpose of God according to election might stand, not of works, but of him that calleth; )
See, your argument is that someone whom the Bible clearly says has done no evil is a sinner. That is a ridiculous argument.
Now, it is true that the scriptures say "For all have sinned and come short of the glory of God". This seems to be a direct contradiction, but we know the scriptures cannot contradict themselves.
So what is the answer? The answer is that Romans 3:23 is speaking of adults, or at least of persons old enough to understand right from wrong.
Even after a person is saved he is still a sinner, simply a sinner saved by grace. There is no such thing as an "innocent" person on earth. No one is excepted. ALL are sinners, whether by nature or by deed; certainly most are by both.
In a figure of speech, yes. Paul said he was chief among sinners. But technically, all his sins are forgiven and he was washed white as snow and has absolutely no sin.
Your inconsistent argument about using animals as examples of those that are not sinners is a foolish red herring. They are not made in the image of God. They do not have a will to choose. Furthermore they are under the curse, and do not live in harmony. When the curse is lifted they will once again live in harmony. This argument is one of the most foolish I have ever heard. Are you as dumb as an animal or are any animals as computer literate and able to think and reason at the same level you can (whatever that level may be)? When you can answer that question honestly then you realize that you cannot use the argument that "animals are not sinners". It is plain foolishness.
It is not a foolish argument at all. It shows that sin does not result directly in physical death. Animals cannot sin, yet they die. Therefore, physical death does not prove one is a sinner. You may not like that, but it is absolutely true and perfectly logical.
Now, God said Adam and Eve would die in "the day" that they sinned. Did they physically die that day? Nope. So this was not the death God spoke of, he spoke of spiritual death, which is separation from God.
But scripture doesn't show we are born spiritually dead. Paul said he was "alive" without the law once, but when the commandment came, sin revived and he "died". He could not have been saying he physically died, so we know for a fact he is speaking of spiritual death. Therefore, when he said he was alive without the law once, he meant before he knew the law he was spiritually alive. He was not dead in sin or separated from God.
Rom 7:7 What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.
8 But sin, taking occasion by the commandment, wrought in me all manner of concupiscence. For without the law sin was dead.
9 For I was alive without the law once: but when the commandment came, sin revived, and I died.
10 And the commandment, which was ordained to life, I found to be unto death.
11 For sin, taking occasion by the commandment, deceived me, and by it slew me.
This scripture is very straightforward and simple. It is clearly describing when Paul learned the law as a young Jewish man. He said he would have not known sin but by the law, he would have not known lust except the law had said, thou shalt not covet.
Paul thought that the law would lead to life, but instead, knowledge of the law made him accountable before God and convicted him as a sinner, therefore he spiritually died.
That is what this passage is saying, plain as day. But because you hold the false doctrine of Original Sin you must wrest this scripture with all sorts of convoluted theories.
As I showed earlier, 1 Peter 2:25 shows we were not born dead or estranged from God. It shows we were Jesus's sheep until we went astray, but now we are RETURNED to the Shepherd and Bishop of our souls. Any honest person easily sees this shows we were not born dead in sin separated from God.
But you just go on and believe that Catholic hack from the 5th century and see where it gets you.
