What you believe matters because your beliefs govern your behavior. It is of utmost importance that you search out the truth and believe it because your behavior reflects what you truly believe. Some biblical examples of people's behavior illustrating what they truly believed were: Adam and Eve, Noah, Abraham, and Mary and Joseph. We want what we believe to be the truth, but that is a backwards approach; instead, we must believe Jesus to be Truth and God's Word to be Truth. Our lives must be built on believing the Truth, otherwise, we are deceived.
