John 14:28-29

14:28 You heard me say to you, ¹  ‘I am going away and I am coming back to you.’ If you loved me, you would be glad ²  that I am going to the Father, because the Father is greater than I am. ³  14:29 I have told you now before it happens, so that when it happens you may believe. ⁴ 

[14:28]  ¹ tn Or “You have heard that I said to you.”

[14:28]  ² tn Or “you would rejoice.”

[14:28]  ³ sn Jesus’ statement the Father is greater than I am has caused much christological and trinitarian debate. Although the Arians appealed to this text to justify their subordinationist Christology, it seems evident that by the fact Jesus compares himself to the Father, his divine nature is taken for granted. There have been two orthodox interpretations: (1) The Son is eternally generated while the Father is not: Origen, Tertullian, Athanasius, Hilary, etc. (2) As man the incarnate Son was less than the Father: Cyril of Alexandria, Ambrose, Augustine. In the context of the Fourth Gospel the second explanation seems more plausible. But why should the disciples have rejoiced? Because Jesus was on the way to the Father who would glorify him (cf. 17:4-5); his departure now signifies that the work the Father has given him is completed (cf. 19:30). Now Jesus will be glorified with that glory that he had with the Father before the world was (cf. 17:5). This should be a cause of rejoicing to the disciples because when Jesus is glorified he will glorify his disciples as well (17:22).

[14:29]  ⁴ sn Jesus tells the disciples that he has told them all these things before they happen, so that when they do happen the disciples may believe. This does not mean they had not believed prior to this time; over and over the author has affirmed that they have (cf. 2:11). But when they see these things happen, their level of trust in Jesus will increase and their concept of who he is will expand. The confession of Thomas in 20:28 is representative of this increased understanding of who Jesus is. Cf. John 13:19.
