Bright, Bold & Blessed
Introduction
Bright Truth
More important to the immediate context, the theme of light is not unrelated to the question of truthfulness and witness in the following verses, for light cannot but attest to its own presence; otherwise put, it bears witness to itself, and its source is entirely supportive of that witness.
So Jesus goes over the same ground he has been over before (5:19–30, 36–37), using slightly different terms. He can, he says, offer true (alēthēs, cf. notes on 5:31) testimony concerning himself, because he knows his unique origin and destiny (an important theme in the Fourth Gospel: cf. 3:11–13; 7:27–28, 34–35; 9:29–30; 13:1, 36–38; 14:4ff.; 16:5, 28; 19:9). His opponents have no right to speak, since they do not know where he came from (viz. the Father, 5:36–37; 16:28) nor where he is going (viz. the Father, 13:1; 16:28; 17:5). He will shortly point out once more that even in these claims he is not speaking in naked independence, but is speaking in perfect conformity with the Father’s will (vv. 16, 18).

Bold Statement
But as in 7:19 (cf. notes there), your law seems appropriate precisely because the Pharisees are appealing to that law to question Jesus’ practice, while Jesus is claiming to be the new locus of revelation from the Father such that the law finds fulfillment in him. Unless one is arbitrarily prepared to argue that Jesus had no consciousness of his unique role in the sweep of redemptive history, in his role as the agent of creation (1:3), in his pre-existence (8:58), it would be astonishing if he had not distanced himself from the law at certain points.
