...Problem is most christians will not accept an atheist knows more about the bible and are able to pick those unsavoury parts that christians ignore and so they make claims like, "I think it would be reasonable to read the whole book and not cherry pick"
Ok, so, if you know the whole Bible, why, in the sword case, it is ignored this:
Behold, one of those who were with Jesus stretched out his hand, and drew his sword, and struck the servant of the high priest, and struck off his ear. Then Jesus said to him, "Put your sword back into its place, for all those who take the sword will die by the sword.
Matt. 26:51-52
I think no one should ever trust what atheist say, always one should check what is really said.
