Would you read a book/see a movie about....?

Gotta keep this short enough to post. An angel knows that the antichrist has been born and he wants to warn humanity and save as many of them as possible. God forbids him from interfering since some of these events need to unfold. The angel learns of a way to defy God and attempt to help humanity. The angel transubstantiates (becomes human by choice) so that he can go to earth and challenge the antichrist. The antichrist is alive and nearing adult hood. He is powerful with many followers and knows that the angel is on earth. In fact it was he that tricked the angel into betraying God and transubstantiating because he knew the angel would lose his powers if he did so and would not be a threat to his rise and could be killed. But it took years to find the angel and in that time the angel was living life as a human. Betrayed and weak, he hides his valued angelic treasures like his flaming broad sword and his holy armor because he knows he will need it if he wants to stand up to the antichrist as a human. In that time the ex-angel met a woman and fathered a child. Soon the antichrist has the angel killed once he was found. The son of the angel grows up without knowing of any of this until he finds some info about his father including where his angelic weapons where hidden. He finds these powerful artifacts and learns the truth about the end of the world. He now has a choice to make, face his religious questions and obey the will of God or defy God and stop the antichrist and the epic war he will start as he is now in power…. I still got bugs to work out but that’s the idea.
