2 John 1:9
Anyone who runs ahead without remaining in the teaching of Christ does not have God. Whoever remains in His teaching has both the Father and the Son.
Berean Standard Bible
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.
Whoever transgresses and doesn’t remain in the teaching of Christ doesn’t have God. He who remains in the teaching has both the Father and the Son.
