It’s a mystery, but you become bound as one because of Jesus living inside each of you.
Ephesians 5:30b to 32. “…because we are members of His body. For this reason a man shall leave his father and mother and shall be joined to his wife, and the two shall become one flesh. This mystery is great; but I am speaking with reference to Christ and the church.”
If you love Jesus, then He lives inside your spirit forever, and you join His family. Jesus and His church of followers are spiritual family.
As a member of Jesus’ spiritual body of believers, you are to leave your parents and join into a new family with your spouse.
Jesus is to live inside each of you as you make your covenant to one another.
It’s a mystery, but you become bound as one because of Jesus living inside each of you.
