2 John 1:9-11

Riverside(i) 9 Every one who goes forward and does not remain in the teaching of Christ is without God. He who remains in the teaching, he has the Father and the Son. 10 If any one comes to you and does not bring this teaching, do not take him into your house and do not bid him welcome. 11 He who bids him welcome becomes a sharer in his wicked works.
