In the Lay of Harbard Thor actually loses his verbal war of words with the ferryman Harbard, from whom he was trying to get a ferry ride across a river. They exchange insults, but Thor loses and winds up having to walk further up river to find a crossing. On the flip side of this type of story is the Lay of Alvis, where he bargains with the Dwarf Alvis for the hand of his daughter Thrud, who was promised in marriage, we may assume, by another God or Goddess. Thor wagers that Alvis cannot answer every question that He puts before him. The Dwarf wins the bet but loses his chance to marry because Thor has kept the Dwarf up until the break of dawn where the rays of the Sun kill him. This story of Thor using his wits instead of his might is very unusual in the Eddas.
Then there is the complex story of Thor's meeting with Utgard - Loki. In this story Thor is tricked many times by Utgard - Loki into thinking he is weaker than the Jotuns who are testing him. On the surface the story seems to show Thor as a foolish and weak God, but at the end of the story the Jotun, Utgard - Loki, tells Thor that he used strong magic to fool Him and that they were truly terrified by the amazing feats that Thor had performed. His wrestling match with Elli, who was actually old age, is an excellent story within a story. "For truly no one can defeat old age", says Utgard - Loki.
He shows His compassion for humans, in Gylfaginning, when he quells his anger after Thjalfi breaks the goats thigh bone to get at the marrow inside. The next morning when Thor consecrates his goats back to life one of them comes up lame. Thor is furious ! However, when he sees the fear in the father's eyes he does not hurt any of them and instead takes Thjalfi and Roskva as compensation. They accompany Thor on many adventures and Thjalfi especially helps Thor several times.
In the Poetic Diction, Thor is challenged to a wild west type of a duel with Hrungnir. We are told that they both throw their weapons at the same time, and hitting in mid - air, the hone thrown by Hrungnir was shattered with one piece lodging in Thor's head. Thor's hammer ran true striking Hrungnir dead. An interesting side story in this is that Hrungnir fell on top of Mighty Thor but no God could lift him off. Later Magni, Thor's 3 year old son with Sif, comes by and easily lifts the lifeless Jotun off of Thor, commenting that his father should have called him, for he would have killed the Giant with a single blow of his hand.
One of the most interesting stories to me is not in the Eddas but in the Sagas. It is in the Seven Viking Romances and it's title is King Gautrek. There is a verbal exchange between Thor and his father Odin that shows a rift between the two that I only found one other time. Odin gives blessing after blessing to Starkad while Thor counteracts every blessing with a curse. In my opinion it is a very interesting exchange indeed ! The only other story of conflict between the father and son is when Thor tries to give Magni the horse Gullfaxi for lifting the Jotun Hrungnir off of him. Odin becomes incensed and demands the horse for himself.
I believe as Sveinbjorn Beinteinsson does that Thor is the Highest of Gods, deserving of the most praise. In the Eddas and the Sagas he definitely seems to have the body of work to back it up. I love reading his stories over and over again. I never get tired of them. I guess when you have great works of literature they literally never get old !
Go with Odin's wisdom, Freyja's love and Thor's protection !
