2 John 1:10

8Watch yourselves, that we don’t lose the things which we have accomplished, but that we receive a full reward.

9Whoever transgresses and doesn’t remain in the teaching of Christ doesn’t have God. He who remains in the teaching has both the Father and the Son.

10If anyone comes to you and doesn’t bring this teaching, don’t receive him into your house, and don’t welcome him,

11for he who welcomes him participates in his evil deeds.

12Having many things to write to you, I don’t want to do so with paper and ink, but I hope to come to you and to speak face to face, that our joy may be made full.
