In my opinion, Christians have done an abysmal job. What do you think?

May be that is why so many responses to questions regarding faith and the Bible are ignorant and void of any real knowledge of scripture. Based on some of the responses I see on YA, the Christian community as a whole has done a pitiful job representing the Kingdom of God while here on earth. As ambadors for Christ, we don't study and learn His will. We claim to be Christians, but don't make the effort to represent him clearly to the rest of the world. There are some well intended people who frankly do more harm than good. I think it's best to live by Christian example. Do you agree?
