Be on your guard against teachers of false doctrine, so that you will receive your complete reward of being with God eternally. Do not welcome or encourage any of these false teachers in any way.

2 John 7-11

7 Many people who deceive others have left your congregation and have now gone out among other people who are in your area [MTY]. They are the ones who ◄do not acknowledge/refuse to say► that Jesus Christ became human. They are the very ones who deceive people and oppose what we teach about Christ. 8 So be sure that you do not let those teachers deceive you! If you let them deceive you, you will lose the reward which we, together with you, have been working for, and you will not receive the complete reward of being eternally united to God! 9 Those who change what Christ taught and do not continue to believe what he taught do not have a relationship with God. But those who continue to believe what Christ taught have a close relationship with both God, our Father, and with ◄his Son/the one who is also God►. 10 So when anyone comes to you who teaches something different from what Christ taught, do not welcome him into your homes! Do not encourage him by ◄wishing him well/greeting him as a fellow believer► in any way! 11 I say that because if you treat people like that as you would treat a fellow believer, God will punish you along with them for the evil that they do.
