John 14:29

14:29 I have told you now before it happens, so that when it happens you may believe. ¹ 

John 4:48

4:48 So Jesus said to him, “Unless you people ²  see signs and wonders you will never believe!” ³ 

John 11:15

11:15 and I am glad ⁴  for your sake that I was not there, so that you may believe. ⁵  But let us go to him.”

[14:29]  ¹ 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.

[4:48]  ² tn The word “people” is not in the Greek text, but is supplied to indicate that the verb is second person plural (referring to more than the royal official alone).

[4:48]  ³ tn Or “you never believe.” The verb πιστεύσητε (pisteushte) is aorist subjunctive and may have either nuance.

[11:15]  ³ tn Grk “and I rejoice.”

[11:15]  ⁴ sn So that you may believe. Why does Jesus make this statement? It seems necessary to understand the disciples’ belief here in a developmental sense, because there are numerous references to the disciples’ faith previous to this in John’s Gospel, notably 2:11. Their concept of who Jesus really was is continually being expanded and challenged; they are undergoing spiritual growth; the climax is reached in the confession of Thomas in John 20:28.
