Who is Miriam Altman from Redeeming Love and what is their importance?

Miriam is the oldest of the Altman children, and only a few years younger than Angel. She is a very kind and obedient daughter, the first "good girl" Angel has ever met. However, she is constantly surprising Angel because, while she is good, she is also very funny, full of life, and curious about people who are different than herself. Miriam wants to be Angel's friend, and declares Angel to be brutally honest for telling her the truth about her past. Miriam is always able to see the best in people, which often puts her at odds with Paul's opinions about Angel, and Angel's about Paul. Miriam is a wonderful young girl, full of excitement about the future, and not afraid to be honest and genuine.
