I agree with what you have said. Some Christians are too quick to forget that we are called in the Bible to be good witnesses and to be a light unto the world and that the best way we can do this is through our actions, not our words. My advice, be wary of Christians that would have you believe the Bible and its contents are not set in stone and are open to change. The Bible is God's word and is not open to numerous interpretations. With enough study anyone can learn it consistently upholds the same principles throughout its entirety, with respect to certain traditions being abolished in the New Testament, and that it does not contradict itself.
