1 Peter 4:17 - For the time that judgment must begin at the house of God: and if it first begin at us, what shall the end be of them that obey not the gospel of God? Heb 3:6 - But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end.
Jesus was sent (after Baptism) to build a House for God = The Almighty God and Father (2 Sam 7:12-14). Hence Jesus said the likes of, I go to my Fathers house and prepare a place for you.
