Is the Despair Portrayed in Psalms and Job Descriptive or Prescriptive?

Questions about whether the despair portrayed in Psalms and Job is descriptive, prescriptive, or something else, whether the Beatitudes are descriptive or prescriptive, how to meditate on God’s Word, and whether reading the Bible gives us information about God or a relationship with him.   Should we view the despair of believers portrayed in Psalms and Job descriptively, prescriptively, or some other middle way? Are the Beatitudes found in Matthew 5 descriptive, prescriptive, or both? How do we meditate on God’s Word just by reading it, and how is meditating on God’s Word different from yoga? How should I respond to someone who says, “The Bible gives us information about God. You can’t read it again and again and say you have a relationship with God.”
