2 John 1:4-7

How happy I was to meet some of your children and find them living according to the truth, just as the Father commanded. I am writing to remind you, dear friends, that we should love one another. This is not a new commandment, but one we have had from the beginning. Love means doing what God has commanded us, and he has commanded us to love one another, just as you heard from the beginning. I say this because many deceivers have gone out into the world. They deny that Jesus Christ came in a real body. Such a person is a deceiver and an antichrist.
