All have sinned.
How can the child possibly be "Innocent", "for all have sinned".
If you deny the Biblical Teaching that all have sinned, just say so:
Ezekiel 18
The Soul Who Sins Will Die
1 The word of the LORD came to me: 2 "What do you people mean by quoting this proverb about the land of Israel:
" 'The fathers eat sour grapes, and the children's teeth are set on edge'?
3 "As surely as I live, declares the Sovereign LORD , you will no longer quote this proverb in Israel. 4 For every living soul belongs to me, the father as well as the son-both alike belong to me. The soul who sins is the one who will die.
