Everyone believes their version of Christianity or bible interpretation is the correct one.  When you disagree with your church,  just hop to or start another one.  And that is how religious denominations came about.  But they all can't be correct when they vary in so many of the doctrines in God's word.  Though we understand that no one can get it ALL right, we believe there is only one correct interpretation of scripture.  We get it only by rightly dividing God's word.  We have no private interpretation, only a literal one in the dispensational context in which it was meant as it is progressively revealed.
