When Laban heard the news about his sister’s son Jacob, he ran to meet him; he embraced him and kissed him, and brought him to his house. Jacob told Laban all these things, and Laban said to him, “Surely you are my bone and my flesh!” And he stayed with him a month.
Well isn’t this interesting? Rachel’s father says the same the marital vows to Jacob that Adam said to Eve. It just goes to show you that marrying one person is, quite literally, marrying their family. This is what covenant is. Think of the implications for church life as well. When someone joins the church they’re joining the entire family. This is why it is so deeply flawed to see Baptism as one’s individual “public declaration”. It is the marital vows of God and his family toward us that bring us into the family.
