Text messages from (God)?!?

It sounds like the guy who likes her is finding a unique, or creepy depending on your point of view, way to tell her so. It is not actually from God. First, if God is real, he would probably find a better way to tell your friend something then a text message. Second, he probably has bigger fish to fry then your friends relationships. Either it is the guy, or someone is playing a prank on your friend.
