The problem lies with fallible humans and their flawed reasoning of the scriptures, not with the bible.
Matthew 7:21-27 speaks as to my stance, and is contrary to my supposed logic. It goes to show that the mere claim to being a Christian or a believer isn't a guarantee that those ones will be viewed favourably by the lord at the end. Given the diversity of belief in religion, and what God's words in the bible commands humans to do in order to show their love for God, most religions don't do what God asks of them. So, not all are the same. Not all are right. In fact, the bible says that few are the ones finding the way that leads to life everlasting. This, to those that believe what the bible says, shows that most supposed Christians will be found to be false in the end.
