Supernatural & Religion
There are many themes and storylines present throughout the 14 seasons of the show, but the main theme is the continuous fight between good and evil.
The angels in Heaven are at war with the demons in Hell and the king of Hell him self, Crowley.
Lucifer makes several appearances trying to gain the title of King of Hell after being released from the cage God and the arch angle Michale had captured him in several years ago.
Sam has struggled throughout many storylines and episodes with his own battle of good vs. evil. When he consumes demon blood he gains some demonic powers and grows strong enough to take down Lucifer, he battled with saving the world but the fact he could risk his good side and morals in order to do so caused a lot of turmoil for youngest Winchester. But at the end the good in him outweighed the Evil and he also helped save the world.
"For example, Sam is a hunter along with his brother, but he was fed demon blood when he was a baby which caused him to possess demonic powers. Because Sam possesses these powers, Lucifer wants to overtake his body. This is just one example of the constant struggle between good and evil in the show."(Garlow, 2013)
In the video clip, Sam is using his powers that grow stronger when he consumes demon blood. However he is using his powers for good not evil, no matter how it changes him.
While Sam has battled with some evil, and weather or not to use his demonic powers to defeat evil beings, Dean has struggled as well. Dean has been chosen by God to save the world, however he struggles with accepting this fact.
"Dean indicates a belief in Heaven (having previously believed only in Hell, odd as that may seem), and two episodes later, in “When the Levee Breaks,” Castiel reveals that Dean, not Sam, is the one whom God has chosen to end the Apocalypse, if he will accept the task. In another very moving scene, Dean promises Castiel, “I give myself over wholly to serve God and you guys,” and swears “to follow His will . . . swiftly and obediently.” Dean’s colloquial language makes the scene very true to his character and quite persuasive, and the analogy to a Christian conversion is obvious." (Karnick, 2009)
In the newer season, Dean actually says yes to Michale, and allows him to use his body as his vessel and walk the earth all in order to defeat Lucifer and save Sam once again. In the video clip below we see the moment Dean says yes to Michael.
