2 John 7–13 (NKJV)
John has just opened his letter to the elect lady with an admonition to obey the long-standing commandment to love one another. Now, he moves into a warning against antichrists and deceivers.
7 For many deceivers have gone out into the world who do not confess Jesus Christ as coming in the flesh. This is a deceiver and an antichrist. 8 Look to yourselves, that we do not lose those things we worked for, but that we may receive a full reward.2 John 7-11
9 Whoever transgresses and does not abide in the doctrine of Christ does not have God. He who abides in the doctrine of Christ has both the Father and the Son. 10 If anyone comes to you and does not bring this doctrine, do not receive him into your house nor greet him; 11 for he who greets him shares in his evil deeds.
John calls out deceivers who have carried on a campaign of lies, not confessing Jesus Christ as having come in the flesh. He uses the word ἀντίχριστος in the Greek language, which translates literally to antichrist, or against Christ. This person seeks to deceive believers and others who would call upon Christ by attempting to debunk His physical existence on earth as a myth. John calls upon the readers to be diligent in their faith and not lose the truth that they worked for. Standing faithful in the truth of Christ is the way to earn the full reward of God to those who believe. Whoever believes the lies of the antichrist does not have a relationship with God. If you abide in the doctrine of Christ, you have relationship with the Father and the Son. To maintain right relationship with all members of the triune Godhead, one must deny the evil antichrists and reject their foul doctrine. As a matter of fact, John instructs them to not even allow him into their houses or to greet those antichrists. Identify the false teachers and deny them access to your life! To even acknowledge this man is to share in his evil and be held responsible for his heresy. Avoid the false teacher and do not get his scent on your pure soul.
12 Having many things to write to you, I did not wish to do so with paper and ink; but I hope to come to you and speak face to face, that our joy may be full.2 John 12-13
13 The children of your elect sister greet you. Amen.
John then closes the letter with a message that he hopes to visit the elect lady and speak face to face. His heart is encouraged by the joy that would come from such a visit. He then offers greetings from a sister of the elect lady and her children. No doubt, the elect lady is a valued person in John’s world, and he longs to protect her from this particular threat, as well as teaching her the ways of Christ more clearly. Oh, to have a mentor that would care for one’s soul as John cared for her’s!
