1. She was troubled

And because the LORD had closed her womb, her rival kept provoking her in order to irritate her. This went on year after year. Whenever Hannah went up to the house of the LORD, her rival provoked her till she wept and would not eat.

2. She was prayerful
1 Samuel 1: 10, 12-13
In bitterness of soul, Hannah wept much and prayed to the LORD…As she kept on praying to the LORD, Eli observed her mouth. Hannah was praying in her heart, and her lips were moving but her voice was not heard. Eli thought she was drunk.

3. She was grateful
1 Samuel 1: 20-22
So in the course of time Hannah conceived and gave birth to a son. She named him Samuel, saying, "Because I asked the LORD for him. When the man Elkanah went up with all his family to offer the annual sacrifice to the LORD and to fulfill his vow, Hannah did not go. She said to her husband, "After the boy is weaned, I will take him and present him before the LORD, and he will live there always."

4. She was faithful
1 Samuel 1: 27-28
I prayed for this child, and the LORD has granted me what I asked of him. So now I give him to the LORD. For his whole life he will be given over to the LORD.
