It doesn't matter if you know or think you're included, if you don't know what you're included in. If you think you're just included in a club, a business, a timeshare, a brand, an ideology, or a particular branch of Christianity, then you're missing the point. This is about being bled into union with Christ. It's not about you making God your father. It's about coming to an understanding of what he has done on the cross and surrendering to allow his love and his father's heart redefine your whole identity.
