Jesus is different to a lot of other people so while I can say that I don’t have any friends in the usual way that humans have friends I actually know that Jesus loves me. If someone loves you and they aren’t your family that usually means they are your friend doesn’t it, even if you don’t know that they love you? For example, someone could have done something really nice for you because they love you but you didn’t know about it. But whether you know about it or not doesn’t make any difference because they love you so they are your friend even if you can’t see them because you didn’t know?
