Final answer:
Religious believers may not believe in predestination because it conflicts with the concept of free will, raises questions about God's goodness, and challenges the purpose of tests and trials.
Step-by-step explanation:
Religious believers may have reasons for not believing in predestination according to scriptures. Firstly, predestination conflicts with the concept of free will. If God has already decided all events and the salvation of individuals, it raises doubts about the existence of genuine choice and personal responsibility. Secondly, the idea of predestination raises questions about the nature of God's goodness, as it implies that God knowingly allows evil to occur. Finally, predestination challenges the notion of meaningful tests and trials since the outcomes are predetermined, rendering the purpose of these tests questionable.
