What can you learn from Jeremiah about faith and trust in God?

Jeremiah is a religious man, especially after surviving the tornado disaster and his faith seeps into the other family members. Reuben is often the only witness to his father's miracles and both of his children agree to go after Davy in a direction that is purely based off of Jeremiah's faith that he will find his son. It is this kind of faith that people can learn from. People need faith to find meaning in life and to help them believe in times of distress.
