One thing I know—THE BIBLE DOES NOT CONTRADICT ITSELF. If A theology does not harmonize with all other scriptures in the Bible then there is something wrong with that theology.
There are a few different interpretations all different from the others.
I believe the bible teaches that we are born with corrupted natures but not as sinners.
We are not guilty of sin until we choose to sin. We are not born with the guilt of Adam's sin.
But because we are fallen or because we inherit a nature that is sinfully inclined, selfish by nature, we all end up sinning.
We are not guilty of sin but inclined to sin when we are born.
JESUS came to save us from sin.
To save us from....
Sins we choose = justification
Sinful inclinations = sanctification
All sin s for ever = glorification
Total salvation.
