Is 'Supernatural' Building to the Return of God ... Again?

Although Sam and Dean might've gotten the blood of a most holy man in the episode "A Most Holy Man," they're not that much closer to reuniting with their mother and Jack or defeating the new Michael on Supernatural. It's not that surprising then that "A Most Holy Man" had a lot of discussion about God and his ability (but unwillingness) to wave a hand and solve all problems. The use of God on Supernatural has been wisely sparse but it's always important when he does occur. Given the dire nature of season 13's problems, it seems like Supernatural is setting up another reappearance from the Big G.
