 Yeah, so, I mean, we see early on in Scripture where, you know, God says, you know, it wasn't good for man to be alone, so he made a helpmate. It was very clear that the two became one flesh. So, right, the math in marriage is one plus one equals one. And so, we know from the very beginning how it was structured, but it wasn't really fully realized until you got to Ephesians, and you get into the New Testament, where it was displayed God's sacrificial love, and that we were called to love our spouses. Christ loved the church, and he gave his life for the church.
