Sorry Whynot if I seem to be pedantic but "children" are not mentioned in the scripture you quote and Jesus when he was sacrificed was 30 years old and not a child.
However having said that Jehovah`s Witnesses don`t seem to have any qualms about sacrificing adults and children to Jehovah with their doctrine/policy of no blood transfusions to save a life.
Any reputable Bible scholar knows that the blood ban is a diet restriction of not eating/consuming blood in this way.
And a blood transfusion is not eating blood ,if a person was only given blood and no food he/she would die of starvation .
Correct me if I am wrong but wasn`t King David `s men excused from this law when they fell to eating meat that wasn`t bled according to the law because they were starving ?
In other words their life was in danger so it was O.K. to disobey that law.
And isnt that why Jesus on occasion broke the sabbath law to save a life ? even if it was a sheep ?
How many lives have needlessly been lost in sacrifice , both children and adults because Jehovah`s Witnesses /Governing Body adopted this policy only since the 1940`s .
