But if they are innocent how did they have sin or a sin nature?
Adam's sin condemned all flesh from birth, dust to dust, without exception,
but Adam's sin didn't condemn any other soul than his own,
Born in sin is a soul born in a body of sin, a soul that will obey the flesh even when it
knows it's act is a
"transgression of the law".
An evil thought is sin, (look/lust) but how many infants can have even so much as an evil thought, much less commit an act it's knows transgresses the law???
Infants die "physically" because of the condemnation of flesh, but not "Spiritually" because the soul has never met the criteria specified by scripture that constitutes sin,
That is knowing the law, knowing sin, and transgressing the law.
Joh 9:41 Jesus said unto them,
If ye were blind, ye should have
no sin: but now ye say,
We see; therefore your
sin remaineth.
Infants are "blind" to sin.
King David knew that when he spoke of his dead son.
