Romans 3:23 all have sinned
Yes. The context being both Jew and Gentile.
Paul is using a legal argument to show the Jews need a Savior just as much as Gentiles.
Jews and Gentiles (men) make
all the people in the world.
What advantage then has the Jew, or what is the profit of circumcision? Much in every way! Chiefly because to them were committed the oracles of God. For what if some did not believe? Will their unbelief make the faithfulness of God without effect? Certainly not! Indeed,
let God be true but every man a liar. As it is written:
“That You may be justified in Your words,
And may overcome when You are judged...”
But now the righteousness of God apart from the law is revealed, being witnessed by the Law and the Prophets, even the righteousness of God, through faith in Jesus Christ, to all and
on all who believe. For there is no difference;
for all have sinned and fall short of the glory of God. Romans 3:1-4,21-23
Can a newborn believe the Gospel?
The context does not include new born babies who may have sin dwelling in their physical body, but do not yet know the difference between right and wrong.
Our discussion is about sin in our body at birth, and differentiating between having sin dwelling in our physical body and being a sinner.
The point that I am making is we are born with a body that contains sin.
A new born baby is innocent, until it grows a knows good from evil, which some call the age of accountability.
So my question would be: Is new born baby a sinner?
IOW, does a new born baby understand the difference between right and wrong, good and evil.
Here is the definition of a sinner.
Sinner - Strongs G268 — hamartōlos
- devoted to sin, a sinner
- not free from sin
- pre-eminently sinful, especially wicked
- all wicked men
- specifically of men stained with certain definite vices or crimes
- tax collectors, heathen
Does this describe a new born baby?
Here’ what Jesus says —
Then Jesus called a little child to Him, set him in the midst of them, and said, “
Assuredly, I say to you, unless you are converted and become as little children, you will by no means enter the kingdom of heaven. Therefore whoever humbles himself as this little child is the greatest in the kingdom of heaven. Whoever receives one little child like this in My name receives Me. Matthew 18:2-5
- unless you are converted and become as little children,
