How being faithful to God can be rewarding

What I noticed in these writings are that it demonstrates how rewarding it can be to be faithful to and serve the Lord. For example: Before St. Francis confronted the wolf, it had to violently kill for food. But when it accepted the Lord, it was no longer violent. People were even generous enough to donate the food to it. It shows how rewarding it can be to renounce one's evil ways and learn to become a loving member of society by following in the Lord. In addition, I thought that Sacred Head is about the unconditional love of the Lord, as the narrator is grateful for the love and grace that God has given to him and wants to always stand by his belief in Him.
