God

God (also known as the Creator, the Lord, or the Man Upstairs) is a supernatural being who is best known for his creation of Archangels, Angels, and Humanity. God is, by far, the most revered supernatural being in biblical lore and is worshiped in accordance with his power.

God has yet to make an actual physical appearance in Supernatural. However, Castiel states at the opening of the fourth season that it was he who ordered Dean Winchester to be rescued from Hell. Also, at the opening of the fifth season, God was responsible for rescuing the Winchester brothers from Lucifer's rising, sending Sam Winchester's addiction to demon blood into remission, and resurrecting Castiel after his destruction at Raphael's hands—things that no other supernatural being is known to truly be capable of. It is revealed as the season progresses that God has mysteriously gone missing. He has taken to walking the Earth, and feels he has intervened enough in the happening thereof, and refuses to help stop the apocalypse.

Origins
Little is known of God's history, or origins. However, it is known that he is the creator of a supernatural dimension known as Heaven where his creations can reside, if they are worthy of it.

To carry out His will, God created from holy fire beings known as Angels. These Angels were answerable to Him without question on pain of banishment. He gave His Angels such powers that they were within the realm of His own and allowed them to occupy and tend to the administration of Heaven, though they are forbidden to disobey His commands and thus are not allowed to have their own free will out of loyalty to Him. Chief amongst these Angels were the Archangels that would be the superiors to all other Angels and God's closest confidants. The four known Archangels were named Michael, Lucifer, Gabriel, and Raphael.

The Creation of Mankind


At some point in time, God crafted what would be his greatest masterpiece: Humanity, a race of beings made in his own image that would populate the Earth and become the dominant species to govern all others.

One key difference between the Angels of Heaven and the race of Humans is that he gave the Human race free will, a gift the Angels do not enjoy by their required code. Despite the possibility that this could lead to mankind being capable of bad deeds, God reasoned that they were by the same token capable of great good if given the proper guidance. Having finished his work in the creation of mankind, God ordered his Angels to honor what he deemed to be his greatest creation by bowing to them.

The War in Heaven and The Fall of the Rebel Angels
It was this request that would forever alter the history of God and His family, as Lucifer, who possessed a rather large ego and questioned his Father's plan privately, now had his faith in God shaken by such a request that he bow to creatures he deemed to be inferior to himself and far inferior to God. Lucifer refused to acquiesce to God's command, stating that he could not in good conscience bow to such flawed creatures capable of performing evil actions. God attempted to help Lucifer see that while Humans were capable of evil, they were equally capable of great good if they were guided properly. Jealous of God's preference for Humans over Angels and equally jealous that Humans were given the gift of free will where Angels were not, Lucifer refused to listen.

Believing that perhaps his faith in God was misplaced, Lucifer's ego got the better of him as he soon became deluded with the idea of overthrowing God and taking His place on the throne of Heaven. He began gathering followers, among these being Azazel, who went on to become one of Lucifer's most devoted followers. Lucifer then approached his brother Michael and pleaded with him to stand with him against their Father due to their Father's preference for the Human race. Michael, not swayed by his brother's charisma and unfailingly loyal to their Father, reacted with revulsion at Lucifer's request and branded him a monster for even thinking of disobedience to their Father.

Eventually, Lucifer felt he had enough supporters to lay siege to Heaven and overthrow God. A great battle ensued between the factions of the Heavenly Host that sided with Lucifer and those that remained loyal to God. Sadly seeing that Lucifer was now beyond help, God ordered Michael to defeat his brother and his fellow rebel angels. Michael did as instructed without question, battling Lucifer personally and beating him down at last in triumph, though this would forever drive a wedge between the two brothers that once loved one another so much. Michael led the Angels still loyal to God to victory over Lucifer's supporters, defeating them and taking them into custody. Lucifer refused to ask for forgiveness and reconcile with his family, his pride preventing him from seeing reason. God decided that, rather than kill Lucifer then, he would banish Lucifer and his followers from Heaven in punishment for their crimes. He ordered them cast into Hell.

While the rebel angels were cast into the pit of Hell and transformed into the first Demons, Lucifer himself was deposited into a separate cage located in the deepest part of Hell with a single entrance (which would be located in the future beneath St. Mary's Convent in Ilchester, Maryland). The entrance to this cage was locked by the 66 Seals, a series of special Seals which would serve to keep Lucifer locked away and keep him from causing chaos for Heaven and Earth by preventing him from leaving his prison uninhibited. Few to none knew where the entrance to his cage lay, with not even his most loyal supporters knowing where it could be located. Azazel was cast into a desert to wander for years in search of his master by Raphael on God's order. With his fall, Azazel eventually was transformed into a Demon as well, coming to be known as the Yellow-Eyed Demon.

Appearances
God has not yet made a physical appearance in the show, though he is frequently mentioned and his presence has been confirmed to have been present on at least one occasion. It is strongly implied that at some point, God will reveal himself in an actual physical appearance, though this will likely be near the end of the Winchester brothers' quest to halt the Apocalypse.

Lazarus Rising
At the opening of Season 4, Dean awakens in his own grave several months after his death at the hands of Lilith's Hellhound. He eventually meets the Angel Castiel for the first time, who reveals himself to be Dean's rescuer from Hell. Dean openly questions why an Angel would rescue him from Hell, to which Castiel replies that God himself gave the command to free Dean from Hell and restore him to life.

Sympathy for the Devil
At the opening of Season 5, the Winchester brothers find themselves trapped within the chapel of St. Mary's Convent in Ilchester, Maryland following the death of Lilith at Sam's hands, which broke the final of the 66 Seals and has caused Lucifer's cage in Hell to begin to open. As the portal to Hell fully opens and the brothers find themselves unable to escape, they fall to their knees as Lucifer's overwhelming presence begins to rise out of Hell and his piercing true voice rings through the structure, believing themselves to be finished. However, it is here that God personally intervenes to save the brothers from Lucifer's rising by teleporting them safely onto a plane passing over Ilchester at that very moment, from which they witness Lucifer's presence shoot up into the sky from the place where St. Mary's stood, heralding the beginning of the Apocalypse. It is also revealed that God personally restored Castiel to life after he was smitten by Raphael.

Good God, Y'all
Castiel seeks to find God so He can put a halt to Lucifer's deeds on Earth, and to do so, he requests to borrow Dean's pendant given to him long ago as a Christmas gift from Sam, who had in turn gotten it from Bobby Singer. The Angel explains that the pendant is a special device that will glow in the presence of the one true Creator, God Himself.

Free to Be You and Me
Dean embarks with Castiel on a quest to locate God so He can put a stop to Lucifer and halt the Apocalypse. To this end, they trap Raphael and interrogate him as to God's whereabouts. Raphael cynically responds that God is dead, to which Dean berates the Archangel to the point that he finally reveals the truth: God is not dead, but has gone missing, having left Heaven and taken to the Earth without leaving any instruction about how to deal with Lucifer's return. This confirms that God is somewhere on the Earth, but seemingly nobody knows where exactly He is or what form He has assumed to walk the Earth.

Dark Side of the Moon
After having been killed by two of their fellow Hunters for their roles in igniting the Apocalypse, Sam and Dean find themselves in Heaven itself and are tasked by Castiel with finding Joshua, the Angel tasked with tending to the central garden that makes up God's kingdom at the center of Heaven and is known to have a direct speaking relationship with God, while dodging Zachariah, who seeks to punish the two brothers for making him look foolish to his peers and then send them back to Earth and force Dean to say "yes" to Michael. With some help from their old friends Ash and Pamela Barnes, the duo are able to get to the edge of the garden, though they are ultimately detained by Zachariah and his cohorts. It is at this moment however that Joshua finds them and sends Zachariah and his company away so he can speak to the brothers.

Taking the Winchesters into the garden, Joshua speaks to them about God, whom he describes as being lonely at times, resulting in His correspondence with Joshua. The brothers demand to see God or know His whereabouts, to which Joshua replies that he has no idea where God is and that he does not have the ability to initiate contact with God. Instead, it is God Himself that initiates contact with Joshua, leaving Joshua clueless as to His whereabouts. However, Joshua relays a personal message from God to the brothers: "Back off." God has tired of them turning to Him to solve the entire problem of the Apocalypse, of which He truly wants no part. Joshua reveals that God, very much aware of the Apocalypse underway and now somewhere on the Earth, has already intervened to help them more than once already, by putting them on the plane to save them from Lucifer's rising and restoring Castiel to life and just now granting Sam salvation to enter Heaven despite his misdeeds. God's basic message is that He wants no part in the Apocalypse and that He will not solve the Winchesters' problems for them, instead pressing them to solve the situation for themselves with the help He has already given them.

After Joshua sends the brothers back to the Earth and restores them to life, Castiel and Dean are left hopeless (Dean dropping the pendant into a wastebasket), though Sam retains hope for their situation and that God may yet reveal Himself when He feels the time is right.

Hammer of the Gods
While they are fighting, Gabriel remarks that Lucifer can stop pretending in front of him and reveals he knows why Lucifer is doing these things to destroy humanity. He further explains that Lucifer had been God's favorite, but when "Dad brought the new baby home" (Humans), Lucifer couldn't take it, and thus is merely throwing a tantrum do display his displeasure before their Father. He also claims that after being around humans for so long, he finally understands why God likes them so much. True, while some are flawed as Lucifer thinks, many of them still try to do better than that and strive to do the good God envisioned them to be capable of.
