Whoever denies the Son, the same doesn't have the Father. He who confesses the Son has the Father also.
"The principle source of confusion in much contemporary study of 1 John is to be found in the failure to recognize the real danger against which the writer is warning. The eternal salvation of the readership is not imperilled [sic]. It is not even in doubt as far as the author is concerned. But seduction by the world and its antichristian representatives is a genuine threat which must be faced." [Note: Hodges, The Gospel . . ., p. 55.]
