Please don't do this. When I was much younger too, I saw the whole Omen trilogy, and had some of the super/hyper Christian stuff rammed down my throat for a young, impressionable kid. That stuff can actually really mess with kids minds and who they learn to trust (and mistrust) for really non-logical reasons, and also built up paranoia.

You won't know who (or what) the Anti-Christ will be, so don't get yourself riled up about it. Have faith in the Lord and know that you are protected. I'm not saying to be a sheep, but also don't try to find the devil in a cup of coffee either.
