1 John 2:18-23

Dear children, the last hour is here. You have heard that the Antichrist is coming, and already many such antichrists have appeared. From this we know that the last hour has come. These people left our churches, but they never really belonged with us; otherwise they would have stayed with us. When they left, it proved that they did not belong with us. But you are not like that, for the Holy One has given you his Spirit, and all of you know the truth. So I am writing to you not because you don’t know the truth but because you know the difference between truth and lies. And who is a liar? Anyone who says that Jesus is not the Christ. Anyone who denies the Father and the Son is an antichrist. Anyone who denies the Son doesn’t have the Father, either. But anyone who acknowledges the Son has the Father also.
