The document is a response to someone saying they feel like a mistake and that no one loves them. It summarizes that:
1) While the person's parents may not have planned them, God did - he knew them and planned their life long before they were born.
2) God specifically created them, determined where and when they would be born, and made no mistakes.
3) God created them because he loves them and had them in mind even before the world was created.
