I want folks to know that not all Christians protest everything that seems to be strange, foreign or weird. There are a group of Christians protesting at the San Diego Comic Con and I say to them there are other things more serious to protest against such as poverty and racism. If you are doing this to get attention and it is not really working.
I have been a Christian all my life and a sci-fi fan all my life. As must as I love Jesus and his amazing life there are many parallels between Christianity and sci-fi stories. Doctor Who, Harry Potter, Superman, Star Wars and more offer themes of good versus evil, friendship, grace and acceptance.
CS Lewis and JRR Tolkien are two fantasy writers who are both Christians. They wrote classics such as Chronicles of Narnia and The Lord of The Rings. JK Rowling who brought us Harry Potter is a Christian too. Many people of our faith were science oriented too.
I pray for safe travel home for all those in San Diego and they are all loved by God.
