2 John 8-10

Amplified Bible, Classic Edition

⁸ Look to yourselves (take care) that you may not lose (throw away or destroy) all that we and you have labored for, but that you may [persevere until you] win and receive back a perfect reward [in full].

⁹ Anyone who runs on ahead [of God] and does not abide in the doctrine of Christ [who is not content with what He taught] does not have God; but he who continues to live in the doctrine (teaching) of Christ [does have God], he has both the Father and the Son.

¹⁰ If anyone comes to you and does not bring this doctrine [is disloyal to what Jesus Christ taught], do not receive him [do not accept him, do not welcome or admit him] into [your] house or bid him Godspeed or give him any encouragement.
