Not rage but a deep sadness. Prayer is indeed the best answer. But, you cannot change the laws of God through prayer, that is going against the law of non contradiction. One has to accept His teachings and not make up our own ones. Remember, "Thou shalt not kill" .
If a person does not follow God's laws or His teachings they are not a follower of His. The Ten Commandments are fundamental, one cannot simply choose which ones suits themselves or not. They are non-negotiable. I appreciate your kind offer for prayers. Thank you.
