A.T. Robertson Commentary John 3:36

"He that believeth on the Son hath eternal life; but he that obeyeth not the Son shall not see life, but the wrath of God abideth on him." — John 3:36 (ASV)

Hath eternal life (εχε ζωην αιωνιον). Has it here and now and for eternity.

That obeyeth not (ο απειθων). "He that is disobedient to the Son." Jesus is the test of human life as Simeon said he would be (Luke 2:34f.). This verb does not occur again in John's Gospel.
