The beliefs and mindsets of people in Christianity often have their roots planted deeply in a doctrinal mix of two very different covenants. We know all Scripture is truth but we can wrongly assume the entire Bible and everything in it is a book that is always meant to apply to us today in a personal way. Paul said to rightly divide the Word of Truth. What form of division is he talking about? The Old Covenant failed, came to an end and was replaced with something much better. The challenge for the typical believer of today is learning to separate these two covenants and having a complete change of mind about the gospel.
