I say this because many deceivers, who do not acknowledge Jesus Christ as coming in the flesh, have gone out into the world. Any such person is the deceiver and the antichrist.
 If anyone comes to you and does not bring this teaching, do not take them into your house or welcome them.  Anyone who welcomes them shares in their wicked work.
I’m going with this.. 2 John is written by the Apostle John to a church, “..the lady chosen by God..” and to the her congregation “..to her children..:”
John here specifically narrows down a set of false teachers who do not acknowledge the truth that Jesus came as God in the flesh and that He will come again to this earth. This would include teachers of Islam and Latter Day Saints. They teach falsely that Jesus was just a prophet or messenger from God, but not that He came to this earth, fully man and fully God.
John is not warning of being around individuals who have been duped into believing the false doctrine. He is warning against being inviting or inclusive to the teachers of false doctrine, and reminding us not to let them teach in our churches. He says that a person who teaches this false doctrine in this way is a deceiver and the antichrist. He further warns that “ Anyone who welcomes them shares in their wicked work.”
We should be eating meat and not only drinking milk. We should know the Truth and who Jesus is. We should be able to discern easily what is false about these false teachings. Unfortunately, it’s not just our churches we need to worry about. False teachers are all around us – at our work place, in our children’s schools, and in our government. Even if it seems politically incorrect, we must turn them away, always being vigilant, watching out for them and what they teach. If we have a question, turn to the only good source for the answer – the Bible. Going to church once a week, or every other week, to hear the Word for 35 minutes is not nearly enough. We need to be immersed in God’s Word every chance we can make. We can’t afford to be confused or mistakenly help someone teach nonsense just because we are not aware it is false. The last thing I would ever want to be labeled is someone who shares in the wicked work of an antichrist!
Lord thank You for giving us Your Word as our guide. Let us not be fooled by these false teachers and especially Lord, help us to be vigilant and to never be used by them in any way to spread their false teaching. In Jesus mighty name, Amen.
