Rom 3:9-18)...no not one, of both the Jew and the Gentile, for all are under sin (v.9). under is hupo - diminution, reduced to a lower value = sin, not the acts of sin but the condemnation of sin from which needs to be removed in order to escape such death, the second death by which a man should perish (damnation)
There is nothing so special about the word Hupo. Under means under, and there's nothing so difficult to understand about it.
sin, not the acts of sin but the condemnation of sin from which needs to be removed
sin=hamartia, and means "offense" or "to miss the mark" or "to violate the the divine law in thought or act."
These are clearly acts of sin, and not imputed sin.
Hamartia does not mean "condemnation of sin."
The same word, "hamartia" is used in Matthew 1:21And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins., but this time it is in the plural: "their sins," meaning the people's sins.
Even here, hamartia means their offenses and not their "condemnation of sin."
In Matthew 3:6 And were baptized of him in Jordan, confessing their sins.It clearly says that people confessed their sins(hamartia). They confessed their sins and not their "condemnation of sin" to John the Baptist.
