@Dale, I have no problem with the Christian’s Confidence.
My concern, (and it need not be shared by everyone, but I wish someone from your “side” would agree that it is or at least could be a valid concern) is that some people think that they are Christians not because they believe in Jesus Christ, Who the Bible says is the Word of God, but because they believe in the Bible, which is the Book of God or even the word of God, but is not God. It is my observation after talking to YEC Christians that this is a real issue.
