Need some ideas for a three part story?

Basically i'm making a three part trilogy about Angels and Demons battling each other. The first book is like these Demons invaded Heaven and begin attacking inside Heaven but the hero of the story stops them along with other Angels. The leader tells them before he dies that Lucifer is rising up again and no one can stop him. The second book takes place a few months after the attack but this time a Human stole the Scroll of the Lamb and is releasing the Horsemen (Death, Famine, Pestilence, War) on Earth and they must track them down and seal them again. The final book is basically an all out war between Heaven in Hell, the Demons break into Heaven and the hero must find the sword of the Apocalypse(made it up), it's the only sword that can harm Lucifer, but the hero discovers he's Jesus so he has to fight his archenemy, Damien the son of Lucifer. I was wondering what to call this trilogy and if i should amke mroe after these three are done. any ideas?
