Stephen Um notes that as evangelicals "began to explore the meaning of inaugurated eschatology for evangelical theology, they were almost always either explicitly or implicitly in conversation with Ladd's work.

Carson sees John 5:24 ("whoever hears my word and believes him who sent me has eternal life and will not be condemned; he has crossed over from death to life", NIV) as giving the "strongest affirmation of inaugurated eschatology in the Fourth Gospel": it is not necessary for the believer to "wait until the last day to experience something of resurrection life.

George N. H. Peters writes extensively on the future-Kingdom approach in his three-volume classic, "The Theocratic Kingdom."

Alternatively, this could be interpreted as the Apostles awaiting for the earthly establishment of Jesus's kingdom in its full glory.
