We see Hannah looking to God in faith. The story of Hannah is at first heartbreaking. She is mocked by her sister wife and has no child. She remembers the faithfulness of the Lord and cries out to Him in her need, trusting that He will hear the cries of His people. In Exodus 3, we see God looking upon the need of the people and answering. To pray in faith is to believe that God hears, sees, and responds to our prayers and needs.
Consider: Exodus 3:7-9
