2 John 1:9 Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son.
[One doctrine; one God only! If you wander from the teachings of Christ, you will leave God behind; but if you are loyal to Christ and His teachings, you will have both the Father and the Son].
2 John 1:10 If there come any unto you, and bring not this doctrine, receive him not into your house, neither bid him God speed:
[If anyone comes teaching/preaching anything other than Christ's doctrines, don't even invite them into your home or church. Don't encourage them in any way. Don't even say God speed to them].
2 John 1:11 For he that biddeth him God speed is partaker of his evil deeds.
[If you encourage or support them in any way, you become a partaker of their evil deeds and wickedness. When you tithe to a church that is not teaching the true Word of God, you become a partaker of those deceptions. Do you want to be in this boat? I hope not. Quit supporting false teachings and repent. Get back on track. It is so simple. Support the teachings of Christ's doctrines only. Support the truth only. Do as God commands, try the spirits; see 1 John 4:1. Do your homework and actually study the Bible. What a concept].
