There is always something a person can be afraid of. Underline in blue things that Ruth might have been afraid of when she was travelling to a foreign land. Underline in red things you are afraid of.
Ruth was afraid of many things but most of all she did not want to commit a sin. That is why she decided to go with Naomi to a foreign land. She understood that only God could forgive her and cleanse her from all her sins. That was the most important thing to her. She believed that God could help her with other things as well.
If you ask God to forgive you, He will do it. Then you can ask Him to help you with the other things you are afraid of.
