Yohanes 4:49

4:49 “Sir,” the official said to him, “come down before my child dies.”

Yohanes 8:58

8:58 Jesus said to them, “I tell you the solemn truth, ¹  before Abraham came into existence, ²  I am!” ³ 

Yohanes 14:29

14:29 I have told you now before it happens, so that when it happens you may believe. ⁴ 

[8:58]  ¹ tn Grk “Truly, truly, I say to you.”

[8:58]  ² tn Grk “before Abraham was.”

[8:58]  ³ sn I am! is an explicit claim to deity. Although each occurrence of the phrase “I am” in the Fourth Gospel needs to be examined individually in context to see if an association with Exod 3:14 is present, it seems clear that this is the case here (as the response of the Jewish authorities in the following verse shows).

[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.
