Once you grant the main premise of the Bible—about the surpassing significance of Christ and his salvation—then all the various parts of the Bible make sense. Because of Christ, the ceremonial law is repealed. Because of Christ the church is no longer a nation-state imposing civil penalties. It all falls into place. However, if you reject the idea of Christ as Son of God and Savior, then, of course, the Bible is at best a mish-mash containing some inspiration and wisdom, but most of it would have to be rejected as foolish or erroneous.
