So, God can come in many forms. He showed up as a burning bush, tounges of Fire, a Dove, and who knows what else. After His Resurrection, people that knew him well didn't recognize him. Maybe you have seen or met him.
Anyhow, the Spirit of God encompasses all and is with every Rock, tree, flower, blade of Grass, insect, mammal, sea creatures, every square inch of Earth, Sea, Sky, stars, planets, Trillions of galaxies...Heaven, and other Realms....maybe even Hell.
So, God can certainly show up in the form of a Fairy, Leprechaun, gnome, ghost, bigfoot, alien, mermaid, Giant one-eyed cyclops or other...and of course Demons can as well.
Im feeling better. Went to some fairy sites and found out there are other Christians who believe in or have seen Fairies.
One lady said she was looking in the mirror and where her hair was parted there was a Fairy with a dime-sized face that looked like Jesus Christ. I've been told I look like Jesus, so who knows, maybe she was just thinking that if it was five foot five six inches taller without butterfly wings it could play in mel Gibson's "the passion of Christ".
