When we rightly divide the word of truth, then our eyes are opened to God's different dealing with different people in different times. Because of that, the new most logical question that arise is "The messages, promises, blessings, gospels that were operational in a different time, are they applicable to us in our time now?"
Historical events and even Bible stories, open up to more than just that - stories. They start to uncover puzzle pieces that will only fit in one spot and no matter how much we try to jam it in to fit where we'd like it to, it won't. A famous preacher once said - "Doctrines misapplied to the wrong period and the wrong time of God's timeline becomes heresy."
