Is the thanksgiving offering obligatory, or is it a free-will offering? Is a person who was ill and then recovered, or who was delivered from some other trouble, obligated to bring a thanksgiving offering? Or, does this person decide on his own initiative to volunteer a thanksgiving offering, so as to express the gratitude that he feels towards God?

By focusing on the thanksgiving offering and the halahkic details that pertain to it, we can understand that the Torah wants to educate people to acknowledge God's goodness and to pay attention to those things for which he must thank God.
