Hannah of the Old Testament demonstrated the power of grief to motivate in positive ways. For years Hannah was unable to have children, a condition that caused her deep heartache. As her grief overwhelmed her, she knelt near the temple and prayed fervently for a child. She explained to the priest Eli that she was “of a sorrowful spirit” and that she was praying “out of the abundance of [her] complaint and grief” (1 Samuel 1:15–16). In time, the Lord answered her prayer by giving her a son, Samuel, who became a great prophet and leader. Hannah’s grief over her childlessness led her to pray, which in turn led to an answer to her prayer. If Hannah had not felt grief, she might not have offered that important prayer.
