B: The correct answer is: teach the consequences of disobedience. The account of Saul's rejection as a king serves primarily to teach the consequences of disobedience. Throughout Saul's reign, he repeatedly disobeyed Göd's commands, which ultimately led to his rejection as king. This narrative illustrates the principle that disobedience to God's will carries serious consequences. Several Bible verses support this interpretation: l. 1 Samuel 15:22-23. Therefore, the primary Purpose of Saul's rejection as king is to teach the consequences of disobedience.
