This question turns out to be a non-question. The phrase that sidelines
the 'question' is the 'if Jesus sinned while on earth'....
This clause is basically semantically contradictory--when you unpack it,
it looks like this:
"If Jesus, who was not able to sin, was able to sin and did so..."(there is a contradiction hiding in there, and therefore the sentence is non-sensical and, as such, is not really a question)
Sorta like: "If a circle was square, would it still have a circumference
of 2 pi r?"---that is NOT a question, but a meaningless string of letters...
I hope this makes sense...but basically the question doesn't exist and
hence requires no 'answer'...
thanks again for writing!
