2 John 1:9,10 - Do not receive him

1:9

Just as we find in 1 John, John is very clear and direct about the nature of false teachings and false teachers. If only we could have the same clarity from church leaders today! If someone does not continue in the teaching of Christ, then they do not have God. Conversely if someone does continue in the teaching of Christ then they have the Father and the Son. If we deny Christ or deny His word, the Bible, then we are denying God. It is not an interesting point of view, it is not something worth considering, it is harmful nonsense that has nothing to do with God. But if we remain faithful to Christ and His word then we have Father and the Son. There really is no option.

1:10

So we now get the clear practical warning, and the primary purpose of the letter. There were many travelling teachers and preachers, and not all of them were good. So if someone came who was not faithfully proclaiming Christ then they were not to be welcomed nor taken in to their homes. There are wolves out there, some dressed in sheep's clothing and we need to be wise to this.
