The same reason that so called "grace" in the new testament fails on a regular basis, the hardness of heart in men and women. It has never been about the law or anything else, it's been about people not caring about themselves or anyone else which has always been at the heart of the matter. We live in a society were everyone wants a crutch to explain away the things that have happened or not happened in their lives. Jesus, God, Satan, Mom, Dad, Teacher, Preacher, Brother, Sister, etc. has done something or not done something to make our lives miserable or even worse, we look to these individuals to somehow make us feel complete. Jesus' main message was about the Kingdom and he constantly pointed everyone who would listen to the path of the Kingdom. Quote: The Kingdom of God is Within You. He said he would show us the way to making our lives more meaningful, so what did he do when he had to make real life choices and decisions? He separated himself from everyone, apostles included, and went deep within seeking the Creators guidance in deep and reflective meditation. And here's the important part, when the answer was revealed he actually did it, what a concept. He obeyed the instructions given and it worked for him each and every time. For all those who claim to "follow" his example, I wonder how much better their lives would be if this example was actually followed? For as the bible itself states "He who knows to do right and does not do it, to him it is counted as sin". Relationships with others is important and we can receive guidance and instructions from others as well, but the person most responsible for our well being is us and no matter what the Creator may or may not offer, if we don't fully accept it and take responsibility for it, it is of no good to us.
